Abstract

An interactive system associated with electronic equipment in which there is incorporated a multifunction switch (270; 271, 271'), a display screen (275) and a cursor (272) that is movable in the X and/or Y direction on the display screen. The multifunction switch has a centrally located, first control element (271) that is non-rotatable, but radially displaceable relative to its central position in order to be able to perform a centre position deviation-based mouse function for control of a cursor or pointer (272), and on depression to be able to perform a switch function, and a second, stepwise rotatable control element (271?) encircling the first control element (271) for movement of a cursor in a particular direction in a menu image, the second control element (271') being depressible at four depression positions in order to actuate a respective switch function associated with the menu image. The system is so designed that, in at least one menu (277), it reproduces on the display screen an animation of possible manipulations of the multifunction switch, and is also so designed that, in a given menu image, it selectively determines whether the first control element (271) has a mouse function and/or a depression-based switch function.

Description

INTERACTIVE SYSTEM ASSOCIATED WITH ELECTRONIC EQUIPMENT

The present invention relates to an interactive system associated with electronic equipment, as defined in the preamble of attached independent patent claims 1, 4, 5, 7, 8, 9, 10, 12, 14, 15, 20, 21, 22, 25, 27, 28, 31, 33, 34, 37, 42, 43, 51, 55, 62, 65, 66, 67, 68, 69, 81, 91, 96, 98, 100, 102, 103, 104, 106, 109 and 111.

It is already known in connection with the input of text or symbols, especially in small apparatus that do not have a complete keyboard like that in, e.g., a PC or typewriter, that the task may be found somewhat awkward. This is because one and the same key is to be used for the input of several letters and/or symbols. It also means that the user must press the same key several times to make the selection he requires. Thus, the object of the present invention is to provide an interactive system which employs multifunction keys for use with electronic apparatus such as mobile telephones, so-called PDAs, pocket PCs, remote control units, calculators etc. The invention will be described in particular in connection with the use of sliding and rotary switches. Such switches are described in more structural detail in other applications such as the Applicant's earlier PCT/NO99/00373 and PCT/NOOl/00057.

To describe the various systems, the present description refers to apparatus such as mobile telephones and PDA/Pocket PCs, but these examples should by no means be regarded as limiting for the present invention. The present interactive system according to the invention is based on there being a display screen able to show or reproduce the possible functions of a multifunction switch, and able to show or give feedback as a consequence of the selections made and the functions operated. Therefore, all screen- assisted and screen-based equipment can be used according to the invention described herein.

Although some applications of the present invention can also be used with the aid of a conventional keyboard, it is preferable, however, to use multifunction keys or switches in the interaction that exists between a chosen switch solution and a display screen, and the following description and attached drawings are therefore intended to illustrate the areas of use of the different switch solutions in interaction with a display screen for different types of apparatus and functions.

The size of the display screen will to a great extent determine how much information it is possible to show. The resolution of display screens of modest sizes, such as the screen of PDAs and mobile telephones, is being improved all the time. This allows clear, high-quality pictures and figures to be shown, which could be crucial in a system where figures or icons are used to describe various functions. The use of a sliding and/or rotary and/or so-called toggle switch construction will allow the different icons to be placed on the display screen in a system which reflects the functioning of the switches. The selection of an icon by moving and pressing the switch in the corresponding position will enable a function or a menu to be split into further sub- functions or sub-menus.

It will be understood that the use multifunction keys, as will be described in connection with the present invention, will enable the available space on a PDA or a mobile telephone, which today is occupied primarily by a keypad with a substantial number of switch keys, to be put to better use as regards increasing the screen size without there being any real change in the physical size of the apparatus.

The characteristic features of the invention will be set forth in attached independent claims 1, 4, 5, 7, 8, 9, 10, 12, 14, 15, 20, 21, 22, 25, 27, 28, 31, 33, 34, 37, 42, 43, 51, 55, 62, 65, 66, 67, 68, 69, 81, 91, 96, 98, 100, 102, 103, 104, 106, 109 and 111, and the sub-claims associated therewith.

The invention will now be described in more detail with reference to the figures which show non-limiting exemplary embodiments of the invention.

Although the illustrated systems and multifunction switches therein primarily are shown and explained in connection with a mobile telephone, it will be understood that the solution is as applicable in other types of apparatus and applications as mentioned in the introduction of the description.

Fig. la shows a multifunction switch having a control element 1 and a total of four depression points I-IV which relate to fields 4, 5 and 6 on the display screen 3. Fig. la in fact shows the prior art according to one of the Applicant's previously filed patent applications. In the illustrated solution in Fig. lb the control element of the multifunction switch is indicated by the reference numeral 1' and the respective depression points are indicated by the Roman numerals I-III and the Roman numerals IV and V, where the Roman numerals I-III refer to X1-X3, whilst the Roman numerals IV and V relate to so-called global functions marked by the reference numerals 6' and 6". When using the switch 1 or 1', a distinction can be made between a long and a short depression at the respective sliding positions Y1-Y5 of the control element. It is also possible to distinguish between different functions either by this sliding function or by the use of a toggle or kick switch function.

As a starting point, it is possible to distinguish between functions in the fields 4 and 5 by a short or long depression. Thus, the field 4 will primarily show main options on a short depression in the individual fields. The field 5 or the row 5 shows other functions and is selected by a long depression. However, it is conceivable that the user can vary this by using a settings menu.

The display screen 3 will be able to vary between showing information and showing input and reproducing different use of functions. It will also be possible to show a selection menu or menus. On the use of a sliding switch, the stepwise sliding positions are indicated by Y1-Y5. The sliding switch shown in Fig. 5 a has five rows. The systems that are to be shown will work according to the same principles, independent of sliding positions. Thus, with reference to Fig. 1, the field 6 will represent a global function, e.g., two degrees of a clear function, i.e., "back" on a short depression at the depression point IV and "clear all" by a long depression at depression point IV on the control element 1. In what follows a "clear" function of this kind will primarily have two functions, where a short depression will function as an "undo" button, i.e., give the possibility of going back to the previous command, and a long depression will delete everything and return to a previous menu or main menu, or effect disconnection (off function). A global function of this kind may in fact be assigned to any one of the pressure positions I-IV in Fig. la or I-V in Fig. lb. In the set-up of functions for a suitable apparatus, there must also be the possibility of a user himself being able to choose the position at which he would like to place a global function of this kind. In addition, there should be no limit regarding the functions which can be assigned to such a position. In the illustrated cases a "negative" function is assigned to the position, but of course there is nothing to prevent such a function being assigned "positive" properties such as "Yes, "OK" etc. Whatever the case, the system will be able to operate all types of functions and in addition have the capability of automatically shifting if this gives advantages during use.

Figs, lb and lc show the multifunction switch control element 1' with five depression points as indicated, i.e., the depression points I-V. Thus, there could be two global functions in this case, as previously mentioned and indicated by the reference numerals

6' and 6", related to the depression points IV and V. Fig. lc also shows how a screen image may appear so as to be in better accordance with the design of a switch. In Fig. lc the switch is either of the type shown in Fig. lb, but where the screen image has been altered, or of the toggle type (kick end switch function) for simulating stepwise movement through steps Y1-Y5. For this reason, the control element in Fig. lb is indicated by the reference numeral 1".

Fig. Id shows a stepwise movable sliding switch with control element 1 which at end positions has a kick switch function or toggle function indicated by positions 7 and 7'.

The switch as shown in Figs, le and If is in reality a multifunction switch in the form of a four-point depressible control element 8 and 8' respectively. Initially, these switches 8 and 8' have a fixed position, but can, as shown in Fig. le, be moved using a toggle function in the Y direction and, as shown in Fig. If, also in the X direction. Without actuation, these control elements 8 and 8' will return to their centre position. Here, it is conceivable that this toggle function or "kick switch function" could replace the sliding functions that are associated with, for example, the switch solution shown in connection with Fig. 1 a.

It is also conceivable that if the user pushes the control element 8 or 8' to a kick switch function in either the Y direction or the X direction, it will be possible to "roll" through the steps in a program sequentially if the control element 8, 8' is somehow held during a pre-programmed time lapse.

A kick switch function of this kind connected to, for example, rapid selection functions is conceivable. Fig. 2 shows rotary switches with certain possible variations. Fig. 2a and Fig. 2b show the prior art according to earlier solutions described by the Applicant in a previously filed patent application. In Fig. 2a, the illustrated solution has a rotary switch 9 which replaces the sliding switch or push switch as shown in Fig. 1. The different steps in a Y1-Y5 taken from the example in Fig. 1 are produced by rotation of the switch control element 9, whilst selection of fields 4, 5, 6 and associated positions XI, X2 and X3 is generated by the use of depression at points I, II and III for positions X1-X3, whilst depression at point IV will activate the global function 6. As in the solution described in connection with Fig. 1 , a short depression, for example, of one depression point will activate field 4, whilst a long depression will activate field 5. The solution according to Fig. 2b has, apart from the step movement, the same mode of operation as shown and described in connection with Fig. lb, and does not therefore require further explanation. In Fig. 2b the control element is indicated by means of the reference numeral 9'.

Fig. 2c shows a control element 9' as indicated in Fig. 2b, with depression points I-V, which are associated with the respective display fields 10-14 shown at the top of Fig. 2c. It will be seen in this figure that what is intended to be shown on the display screen has a direct connection with the appearance and the depression positions of the multifunction switch 9'.

In Fig. 2d the multifunction switch is shown with a control element 15 which has per se the same appearance as the control element 9 in Fig. 2a, but where the control element 15 in addition has a stepwise sliding function for use in apparatus which require definition of additional functions, as for instance described in connection with Fig. 13.

Fig. 2e shows a rotary switch 16 having a so-called toggle function or "kick switch" function. In Fig. 2e the rotary switch control element is shown having a toggle function in both the X and the Y direction. This solution could have special navigation functions for a cursor in a screen image or optionally be used for shifting a screen image or navigation in a screen image by pushing the switch control element 16 in this way in the different directions possible.

Figs. 2f-2h have been included to better illustrate the solution that has just been described in connection with Fig. 2e. Fig. 2f illustrates the distribution of pressure points distributed in four fields, i.e., following the same pattern as shown and described in connection with Fig. 2a, and where Figs. 2g and 2h are related to the distribution of pressure points in a total of five fields following the same pattern as shown and described in connection with Fig. 2b (and in fact Fig. 2c), although the screen image is different. The extended possibilities that are present in this case because a user can by means of kick switch function or toggle function shift to another function, as shown in Fig. 13, or browse though a document, or e.g., a web page, or move a cursor in different directions, will be an advantage. It will thus be easier, as in connection with Fig. 2f, to move from one field 17 to a neighbouring field 17, whilst the global function 18 is present on the display screen 19. Figs. 2g and 2h show an upper field 20 and a lower field 20' on the screen 21 which can be connected to upper and lower pressure points VI and V respectively. The three pressure points I-III in the X direction will control the three fields XI -X3 in the same way as shown and explained in connection with Fig. lb and Fig. 2b. In connection with Fig. 2h, it will be understood that toggling of the multifunction switch control element 22 will cause the upper field 20 of the display screen to move a cursor 23 in the X or Y direction, depending on the direction of movement of the control element 22.

Thus, with the solution shown in connection with Figs. 2e-2h, it will be possible by using the control element that rotates, to browse in a selected menu or move between different categories of menu in addition to that otherwise described.

Figs. 3a-3c show a solution having double rotary switches. In Fig. 3a there are two concentrically arranged, mutually rotatable control elements 24, 25, one of which is designed to control a cursor 26 in the X direction whilst the other is designed to control the cursor 26 in the Y direction. The outermost of the control elements, control element 25, is advantageously associated with at least four fixed-position switches at switch positions 27-30 for activating switch-related functions on depression of the control element 25 at a respective such switch position. As shown in Fig. 3a, the central one 24 of the control elements is designed so that on depression it activates one switch-related function at a depression point 31. However, it is conceivable that also in connection with the central one of the control elements, as indicated by the reference numeral 24' in Fig. 3c, it is possible to have four depression points for this control element too, indicated here by means of the reference numerals 32-35, for controlling respective switch-related functions. The illustrated solutions in Fig. 3 are particularly suitable for use in apparatus which require control of the cursor or movement of text and/or pictures on the screen, i.e., an advanced X, Y navigation facility. It is conceivable that the central switch 24, respectively 24', should be intended to control the cursor or the screen image in the X direction, whilst the outer switch 25 is to control the cursor and/or the screen image in the Y direction. However, the functions of these two switches can be interchanged.

In Fig. 3d there is a variant of the solution shown in Fig. 3c where the inner control element is indicated by the reference numeral 24" and in non-concentric with the control element 25. Basically, these two control elements 24" and 25 could have the same functions as those illustrated and described in connection with Fig. 3c.

The solution shown in Fig. 3e consists of two juxtaposed, independent, rotatable control elements 36, 37, where one of the control elements, e.g., the control element 37, is arranged to control the cursor 26 in the X direction, and where the other control element 36 is arranged to control the cursor 26 in the Y direction. At least one of these control elements 36, 37 could be connected to at least four fixed-position switches at respective switch-related positions, as indicated by the reference numerals 38, 39, 40 and 41 in connection with the switch 36. However, it is also possible that these switches only have a single depression function, as symbolised by the switch position 42 indicated in a broken line in connection with the switch 37.

Fig. 4a shows the prior art in connection with a cylindrical roller switch 43 which in a preferred embodiment has three depression points 44, 45 and 46 for activating respective switch functions. In this solution, rotation of the roller switch will replace a sliding function, as shown and described in connection with, inter alia, Fig. la. The respective switch functions that can be activated in connection with the depression points 44-46 are indicated by the reference numerals 44'-46' in Fig. 4b. However, as indicated by the arrow 47 in Fig. 4b, it will be desirable to also be able to move the roller switch sideways to obtain a toggle function or kick switch function in connection with switches 48 and 49. As shown in Fig. 4c, the switches 50, 51 will be present to detect rotation of the control element 43.

Fig. 4d and Fig. 4e show navigation by using rotation and toggling of the control element 43. For instance, it will be understood that the toggling function in connection with that shown in Fig. 4c will, for example, move the cursor 52 in the X direction , whilst rolling the control element 43 will move the cursor 54 in the Y direction.

Fig. 4f shows a roller switch 53 and an encircling, ring-shaped switch 54 which is stepwise movable, so that, for example, the switch 53 can move a cursor 55 in the Y direction, whilst the control element 54 moves the cursor in the X direction. It will also be appreciated that the two control elements 53, 54 could be used together for navigation on menu pages and for browsing through menus and sub-menus, and also selection of functions in these menus and sub-menus.

Fig. 4g shows a variant of the solution shown in Fig. 4f, where the difference is that two roller switches 56, 57 are used for navigation in the system.

The solutions shown in Figs. 4h-4o are in fact connected to a possibility of extended navigation by being able to navigate in another dimension, so that it is possible to navigate not only in the X and Y dimensions, but also in the Z dimension. The solutions shown in these figures employ a first roller switch 58, a second roller switch 59 and a third roller switch 60. The first roller switch 58 will be rotatable about a first longitudinal axis, the second depressible roller 59 will be rotatable about an axis of rotation transverse to the longitudinal axis of the first roller, and the third roller 60 will be rotatable about an axis transverse to the longitudinal axis of the first roller. The first roller 58 may be depressible either at its centre or both at its centre and at its ends for actuating a respective switch function. The second and third rollers, indicated by the reference numerals 59 and 60, may optionally but not necessarily have depressibility for actuating a respective switch function. Fig. 4n and Fig. 4o show respective switches 61', 62', 63' linked to the depression points 61-63 on the roller 58. Fig. 4o shows switches 64' and 65' linked to respective depression points 64 and 65 on respective rollers 59 and 60, if the depression function is assigned to these rollers. Thus, the respective roller switches 58, 59 and 60 will each have their dimension to navigate in, and, as mentioned, Z navigation could be achieved if there are three roller switch members. This gives excellent possibilities of navigation in relation to the prior art.

Although possible depressions are shown for all rollers in connection with that indicated in Figs. 4h and 4e, and also in connection with Figs. 4n and 4o, it will be seen that the solutions shown in Figs. 4j and 4k only indicate possible depressions in the X direction, i.e., that in the solution shown in Fig. 4j the roller 58 has only one central depression point 62 and the rollers 59 and 60 each have their depression point 64 and 65. In the solution shown in Fig. 4h there is also just one possible depression in the X direction only, and in this case it is only the roller 58 that has its depression points 61, 62 and 63.

The solutions shown in Figs. 41 and 4m have only been included to illustrate the scope for application of the illustrated multifunction switch solution. Fig. 5 a shows a screen alternative where all available main functions and sub-functions are shown. Fig. 5b shows a typical ringing mode in connection with a telephone conversation. In this case fields 66-70 and 71-75 are obtained for the respective Y positions. The display of such an arrangement will enable a user to acquaint himself immediately with the position of the different functions. However, this requires the screen, indicated here by the reference numeral 76, to have a certain size and/or high resolution. A global field 77 with a "clear" function will be present.

The alternatives present in connection with the different fields 66-70 and 71-75 will be distinguishable by a short or long depression in connection with the depression points I- III on the control element 78. As mentioned earlier, the depression points I-III are related to the position X1-X3. The depression point TV is related to the said function

77.

The system can also function such that when a user starts to dial a number, the overview shown in Fig. 5 a will disappear and a screen image like that shown in Fig. 5b will appear. It is also conceivable that the overview can be removed by effecting in position Yl, X2 a short depression in position II on the switch 78 to remove the overview.

As shown in Fig. 5c and Fig. 5d, it is possible, in theory at least, that the interactive system as just described in connection with Figs. 5a and 5b could also be used in connection with a conventional keypad per se which includes a plurality of switches instead of the multifunction switch as shown in Figs. 5a and 5b. In the case illustrated here, as in the case shown in Fig. 5a and Fig. 5b, there will be an activation matrix consisting of at least three columns related to the X direction, i.e., XI, X2, X3, and at least two rows related to the Y direction, and where the keypad, indicated generally by the reference numeral 79, has a plurality of switch keys the position and function of which (X1-X3; Y1-Y5) will be related to corresponding positions and functions in the activation matrix as shown on the screen 76. By means of a long or short depression reduced to a selected X column and Y row position of related key in the keypad 79, the equipment will be triggered to show the rows individually related to the Y position in the menu at a respective selected Y position in the activation matrix.

Furthermore, by means of a long or short depression in a selected Y step position of a Y row related key, it will be possible to cause a relevant function or sub-function to be activated, whilst other functions and/or sub-functions associated with other Y steps for the control element are shown at the same time. Fig. 6 shows a set-up where functions control an apparatus, such as in this case a telephone, with a sliding switch which has just two fixed sliding positions Yl, Y2. It is also possible that these two fixed sliding positions per se could have been replaced by a toggle function.

Fig. 6a shows which functions can be allocated to the two Yl and Y2 rows represented by the fields 80 and 81. The screen image illustrated shows just one of the rows at a time in the illustrated example, but it can of course show all rows if the screen areas so permits. The field 82 shows a function for the global function "clear" (back/delete) which will have two actual functions: "clear" (back to the previous option) on a short depression, or "clear all" (delete everything done previously) on a long depression at position IV on the multifunction switch control element 83. Alternatively, the last- mentioned function may also involve an "off function. As will be evident from the figure, the different main functions are split into groups of three. When a group is selected, it will split into three. This last step is known per se in connection with the input of groups of letters and the splitting thereof in connection with the solution described in an earlier application filed by the Applicant. On the input of, for example, the number 22, see Figs. 6b and 6c, the group to the left associated with depression point I is selected, whereupon the group is split up and the number 2 is chosen, as indicated in Fig. 6c, by depressing depression point II twice.

When selecting a menu, as shown in Fig. 6d, the control element 83 will be pushed down to position Yl and depressed at depression point II. As shown in Fig. 6e, navigation functions then appear which materialise in that shown in Fig. 6f, where up/down arrows are displayed and can be operated by the depression of respectively depression point I or depression point III, and where confirmation can be effected by depression of depression point II.

Fig. 6g shows an example of how it is possible to replace the two-position sliding function shown in connection with Figs. 6b-6f, a multifunction switch 84 being shown together with a shift switch 85 to be able to shift between the Yl and Y2 position for activation of respective fields on the screen.

Fig. 7 shows an alternative where functions in a selection field are divided into two options prior to splitting. This system is not limited to any particular type of switch, but in the illustrated example a sliding switch with control element 87 is shown to illustrate the shifting of functions in the field 86. The set-up of functions will primarily follow a pattern like that shown in connection with the description of Fig. 5.

Thus, Fig. 7 represents a system which can distinguish between the two options that will be present in each group, such as the groups 1, 2; 3, 4; 5, 6. Here, there are in fact six options for each position 86, but it is possible to distinguish between these by a long or short depression related to the depression position I-III. Thus, if the user requires the number 1, he must make a short depression at depression point I. If the user requires the number 2, he must make a long depression at depression point I. By moving the control element 87 into the Y position, it is possible to browse through the options that are in fact available.

Thus, the multifunction switch control element 87 is stepwise movable in the Y direction into at least two Y positions in order to select a desired Y row or a Y position related function or functions or sub-function or sub-functions in the menu image that is shown. By using one of the possible depression points, the user can select and X and Y related function or sub-function, each X position having two sub-positions XI 1, XI 2; X21, X22; X31, X32. Thus, a function linked to a sub-position is activated by a short or long depression at one of the possible depression points.

Fig. 8 shows how a four pressure point, two-way toggle function switch, indicated by the reference numeral 88 in the figure, would work in conjunction with a menu image shown on a display 89 in connection with the present inventive system. The figure shows an example of the use of typical mobile telephone functions. The menu may be composed of icons which represent, for example, a telephone 90, a telephone list 91, calendar/time/diary 92, text message/e-mail 93, PC functions 94, web site/Internet 95, games 96, calculator 97 and a set-up function 98.

When selecting a function in connection with that shown in Fig. 8, the user will, on depression of one of the depression points I-III as shown on the control element 88, be able to select a particular icon and split the icon-related function into sub-functions. To be select such a function, the switch 88 can be pushed or toggled, so that the correct Y row Y1-Y3 is marked, as indicated for example in Figs. 8b or 8c. If, for example, the Y3 row is chosen, and the telephone function 90 is required, the control element 88 is depressed at position I, see Fig. 8c, and groups of numbers then appear as shown in Fig. 8d. Upon a further depression at position I of the control element 88, the group of numbers 1, 2, 3 will be split, as can be seen in Fig. 8e. The depression point IV in this case gives a back function, so that after a telephone number digit has been marked and another group of digits is required, the user returns to the image in Fig. 8d, for selection of the appropriate X, Y position and thus selection of either a group of digits or selection of the ringing function. Once a number has been selected, either by input or retrieval from a telephone book, such as the telephone book 91, the switch control element 81 will be toggled into position Yl and the call is made by selecting position XI by depressing the control element 88 at depression point I, as indicated in Fig. 8f. Fig. 8g shows that whilst a telephone conversation is in progress, toggling in the Y direction would adjust the volume up or down. A phone call is ended by depressing the control element 88 at depression point III, as shown in Fig. 8h.

In connection with that shown in Fig. 8, it should be mentioned that, as shown in Fig. If, it will be possible to move the multifunction switch not only in the Y direction in connection with the toggling function, but also in the X direction. In such a case, it will be somewhat easier to navigate a cursor over the screen and this will be especially suitable for the apparatus types which have many functionalities related thereto, and similarly a large display screen.

Fig. 9a shows a start image where a main option is shown in field 99 and sub-functions in a field 100. The whole menu will be shown when the control element 101 is pressed at position II. The menu will be spread across the whole of main field 102. By pushing the control element 101 through the stepwise positions Y5-Y1, the user can select a desired sub-menu or function. When the depression point I is depressed as shown in Fig. 9b, a calculator function will emerge, as shown primarily in Fig. 9c. The numbers will be visible in the field 99 under position Y2-Y5, whilst the information in the field 100 will on the other hand be constant in the positions Y2-Y5. A better understanding of this can be had not only from Fig. 9c but also from Figs. lOa-lOh. As shown in the figures, = is placed alone as a direct option. However, this should be regarded as merely a suggestion which will the use of such a function faster. The function can be retrieved by a depression of long duration, and is shown in the field 100. Further options could also be placed in sub-menu options or direct as an option in connection with the toggle function. The position Yl will be the same for all functions for the field 99, but will be adapted to the individual function for the field 100, and in this connection reference is made to Fig. lOi.

Figs. 10a- lOi show how it is possible to carry out an arithmetic operation by means of the system and the use of a preferred multifunction switch. The arithmetic operation which will be explained in the illustrated example is for example the number 1059 that is to be divided by 3. First the number 1059 must be entered. This is done by depressing position 1 in position Y5 of the control element 101, which gives the first digit 1. Then pressure point 2 is depressed in position Y2, which gives the additional digit 0, as shown in Fig. 10b. Then the pressure point II is depressed in position Y5, which gives another digit 5, as indicated in Fig. 10c. Then the pressure point III is depressed in the position Y5, which gives the last digit 9. The pressure point III is depressed once more, this time with a press of long duration, whereby the functions/percentage sign will become spread across the field 99, as shown in Fig. lOf. A short press on the depression point I gives "/", i.e., the division function as shown in Fig. lOf. Then pressure point III is depressed in position Y5, which gives the number 3 after the division. Now shown on the screen is 1059: 3. A long press is now made on pressure point I for ' -", and 1059:3=353 thus is obtained via the system's arithmetic function, as shown in Fig. lOh. Fig. lOi shows other options in position Yl.

Fig.l 1 shows a variant of the calculator function just described. In this case there is a control element 101 with depression points I-III and in addition IV for the global function. By shifting between Y2-Y5 the field 104, X2 will shift between different mathematical functions, whilst XI and X3 will retain major functions, here "=" and "0". The number in field 103 will be fixed in the positions Y2-Y5. In position Yl it is possible from field 105 to choose by a long depression a shift of functions at INV or Mode, as shown in Fig. l ie and 1 If.

Fig. 12 shows an alternative system which is in accordance with the pattern described in connection with Fig. 5, where all functions have their place under the numbers in a so- called sub-menu, and where these functions can be retrieved by a long depression. It will be seen here that "=" is located permanently to the left for all the positions of Y2- Y5. Here it will be possible to retrieve the sub-menu so that additional functions are provided by going to Y1U, i.e., INV, Mode, More, as shown in Figs. 12b and 12c. Fig. 12d shows a variant, where the control element in the multifunction switch is of a rotatable type instead of being of the sliding function type. In this case, the control element is for clarity indicated by means of the reference numeral 105. However, the interactive system will also in this case function in exactly the same way as shown and described in connection with Figs. 12a- 12c.

Fig. 13a-13d shows a rotary switch 106 as multifunction switch and having, in the chosen example, four sliding positions Y1-Y4 (related to the centre of the control element 106). This multifunction switch will combine the properties that a sliding switch or a push switch has with the possibilities of rotation. The positions of the switch can be shown on a screen 107, in this case, for example for a mini-PC or telephone. To the left on the screen icons 108, 109, 110 and 111 for certain main functions are shown. Although only four such main functions are shown here, the number will necessarily be limited by the controlling, stepwise sliding positions. A shown previously, such sliding positions can be replaced by toggle-initiated positions. Each main function will be controlled in that the control element 106 is moved to the position shown on the screen. One icon at a time will be marked or highlighted when the control element is in the right position. Fig. 13 shows typical functions such as telephone function 108, Internet/WAP connection 109, diary/calendar/time 110 and supplementary menu 111. In each position, the switch control element 106 will operate according to principles that have been shown and described above. Fig. 13a shows a typical set-up. Fig. 13b shows the control element 106 in position Y4, which is the telephone mode 108. Fig. 13c shows the switch moved to position Y3, the so-called Internet/WAP function. Fig. 13 shows a possible menu arrangement. To move in the menu, the user rotates the switch 106 and a cursor will move over the various alternatives. A press on the control element 106 at position I will result in the activation of "yes", and the user can thus select the function that is highlighted in the list. The list is illustrated here by frames.

By using a multifunction switch of the type shown in Fig. 13a, it will, for example, be possible to conduct a conversation on the telephone without having to log off the Internet/WAP connection. Consequently, it is possible to perform several functions simultaneously by moving the switch control element 106 in order to choose between the different functions. This form of multifunction switch in association with an interactive system provides undreamt-of uses. A major advantage will be that it gives the user the possibility of working with several different functions at the same time by easily alternating between them. One of the advantages of this is that the user can avoid ending input of text if he needs to find information in an Internet/WAP function.

Fig. 14 illustrates the possibilities that a multifunction switch associated with an interactive system would have when used to control, for example, a radio or a CD player. The following example as shown in Fig. 14 is related to an MP3 player which is an application that can easily be implemented in a mobile telephone, a PDA or the like. Fig. 14 shows the selection of MP3 by using rotary switch 112. Options from the menu can be shown either across the whole screen, as indicated in Fig. 14c, or can be rotated into fields 113, 114, as shown in Fig. 14b. Additional functions can be fetched by pressing on depression point II of the rotary switch on the marking of field 113, as shown in Fig. 14d.

In field 113 (which, as described earlier, is controlled by a short depression) main options are shown. Sub-options are shown in the field 114 and it is possible to enter additional sub-menus. In cases where the main field 113 on the screen is occupied by functions, the field 114 can be removed to increase the space on the screen. On rotation of the multifunction switch control element 112, a cursor will be able to move in the Y direction across the menu, see Figs. 14c and 14d. Alternatively, the actual menu can "rotate", i.e., move up and down on the screen and be selected in that the functions are marked in a particular field on the screen, as shown in Fig. 14e. Fig. 14f shows how the functions for playing music can be placed in the screen image. The functions are selected by rotating the switch control element 112 for movement of a cursor in the Y direction, and by depressing the control element 112 in the desired position I, II or III in order to select one of the three different functions in the X direction. In this connection, reference is made to Figs. 14f and 14g. To choose between being able to control the field 115 or 116 (see Fig. 14f), the user presses on depression point IV on the control element 112, which gives "shift". A short press will give "shift" whilst a long press will give "back", i.e., back to the menu or another neutral function. In the main field 116, the system can display a little information about relevant songs or artists it is possible to choose between directly, or permit a further browsing function. The system should also contain a search function where it is possible to write in the first letters of a relevant song or artist, and where a predictive system for the input of text will be able to guess at the relevant songs or artists that are already loaded in.

From Fig. 14g it will be seen that depression of point III on the control element 112 will generate the whole list of artists that is shown in the main field 116.

Fig. 15 shows an alternative display on a display screen in connection with the operation of a rotary switch. Here, the various functions will rotate on rotation of the switch control element 117. There are three groups of functions that belong to the X coordinates X1-X3, and these are selected by depression at the depression points I-III on the control element 117, see Fig. 15a. The different functions will then, on rotation of the control element 117, move into the fields 118, 119 and 120, related to XI, X2 and X3, and be confirmed by depression of respective depression points I, II and III. The field 121 will be controlled by the global function represented by the depression point IV on the control element 117. The rotation may either be step-determined or endless. No matter which, it will not be possible for functions from XI, X2 and X3 to move over to the "wrong side", but there will instead be a change in the respective fields, as indicated in Fig. 15b. The field 122 will capable of use as a main field. To shift between navigation in the fields 118-120 and 122, the user can press down at depression point TV on the control element 117. As shown, a list of artists, for example, then appears through which the user is able to browse by rotating the control element 117. Selection of a desired artist may, for example, be confirmed by a further depression of the control element 117 in position TV.

Figs. 16a- 16c show another alternative where the various functions on the display screen are fixed, but are highlighted successively when the rotary switch 123 is rotated. The relevant, available functions are highlighted or ringed, as shown, or can be pointed to by means or arrows or arms, as for instance on a clock, and in this connection reference is made to that indicated by the reference numerals 124-126. Confirmed selection of the function in respectively XI -X3 is effected by depression at a selected depression point of the depression points I-III, see Fig. 16a. To manoeuvre in the central field 127, a short depression at depression point TV on the control element 123 can be made, i.e., activation of the "shift" function 128. A long depression will result in the activation of the "back" function, thereby allowing the user to move to another main function or menu.

Figs.17a- 17c show alternatively how it is possible to employ a rotary switch having control element 129. In this case, the menu is divided into four sectors or main fields XI -X4 and the user can select the different functions by rotating the control element 129 and depressing one of the four pressure points I-IV on the control element 129 when the right function is marked, as indicated, for example, by the reference numerals 130-133 in Fig. 17b. Depression of the control element 129 at position IV as shown in Fig. 17b will thus activate function III, symbolised by the reference numeral 130. To show which function the user wishes to select, arrows 134 as shown in Fig. 17c may be used as an alternative. For the purposes of illustration, the different functions are indicated by Roman numerals in this case, but these Roman numerals have no relation to the Roman numerals I-IV which are shown on the control element 129. Fig. 18 shows the same set-up as that shown in Fig. 17, but here the operation in association with the interactive system is controlled by means of a sliding switch 135. The markings in this example are shown by arrows 136, and these arrows will rotate either towards the right or the left by pushing the switch element 135 of the multifunction switch up or down between the positions in Y1-Y3. Pressure points I-IV on the control element 135 will be related to the respective fields XI -X4. The Roman numerals given in the fields Xi-X4 have nothing to do with the Roman numerals which for simplicity are shown on the control element 135.

Fig. 19 shows letters distributed in a same system as that shown in connection with Figs. 17 and 18 for the input of text, for example, in connection with the writing of a text message. Groups of letters can be split in a similar way as the groups of numbers, and in this connection reference is made to earlier parts of the present description. The actual text field may be placed in the centre 137 of the display. It is also conceivable that the actual text field could appear as a separate field outside the display area which is shown in Fig. 19. The multifunction switch control element in Fig. 19 indicated by means of the reference numeral 138 and, as in the preceding examples, has four depression points I-IV linked to the fields XI -X4. After each keying in of a letter as carried out in connection with Fig. 19c, a return is made to the starting point as can be seen, for example, in Fig. 19b, in order to select a new letter field that can be split, as, for example, the letter field DEF for splitting by depression of the control element 138 at point III in Fig. 19b, so that instead of A, B and C in Fig. 19c the letters D, E and F appear.

Fig. 20 shows a set-up for interactive use of a rotatable switch 139 which has four depression points I, II, III and IV, and a central depression point V. The menu can be built up according to the same principle as shown earlier, where there is a group of functions that can be split into sub-functions. The centre position, represented by depression point V, will in this case be able to have a global function where it is possible to distinguish between a "clear" function or a "back" function or an "off function. In the ringing mode, as shown, it will be possible to rotate through the numbers by rotating the control element 139. Alternatively, a division of the numbers into groups according to the same system as shown in connection with Fig. 19 is conceivable. The individual depression points I-IV will be related to the fields XI, X2, X3 and X4 as shown in Fig. 20a. On the input of successive telephone numbers, these could be displayed in a separate display field 141, as the digits are successively entered, e.g., in the sequence 2 3 4 6 1 0 9 8. The solution according to Fig. 20 will be particularly suitable in cases when the screen display is essentially circular. As a variant, it is possible in connection with the illustrated screen displays to replace, for example, a rotary switch, as represented by the control element 139, with a touch screen. This is highly conceivable in connection with that shown in Fig. 20, as here it is possible to press directly on the screen in order to activate icons and functions as required. Rotation may optionally be simulated by making a circular movement on a suitable field of the screen.

Fig. 21 shows the use of a multifunctional switch 142 in connection typically with a game. Figs. 21a-21c show the selection of games from a main menu and a sub-menu. As an example, Nokia's "Snake" is shown in Figs. 21e-21f. The multifunction switch, in this case indicated by the reference numeral 142, will provide a rapid navigation because of its four-way design with four depression points I-IV as shown and described in connection with other embodiments. Here, it is shown that in all positions Y2-Y5 it will be possible to navigate the game. By moving the control element 142 into the position Yl, it will be possible to easily interrupt the game or shift to a new game or optionally shift setting or carry out another game-related change function. A rotary switch as shown, for example, in Fig. 2, could operate the game in a similar way. By using the rotation facility of a rotary switch to control said "Snake" the user can, by utilising the rotation, steer the "snake" in the desired direction. A switch position Y2- Y5 143 is indicated in Fig. 21e which could extend the image field or perform a zoom function.

Additional applications of the interactive system according to the present invention will now be described in connection with Figs. 22 and 23. Chess is played to a great extent via the internet. With the developments taking place in mobile telephony and WAP solutions (Internet for mobile), it will be possible in the future to play against other mobile subscribers and at the same time move from one place to another.

Fig. 22 shows how by using a multifunction switch 144 it is possible to play chess in association with that shown on a display screen 145. The switch shown is a four pressure point switch which in addition can be moved in two or four directions. The switch is intended to be able to return to a centre position after actuation.

Figs, 22a-22j show how a four pressure point toggle switch 144 can be used to play chess. Fig. 22a shows the screen image after the user has chosen the type of game from a menu. With a switch of this kind, the user will also be able to navigate horizontally in a menu if this should be necessary or possible. In the illustrated example a choice is given between playing against the computer in, for example, the user apparatus, or playing against another player. Here, other players are considered to be people against whom the user can play, either by sending a message about the chess moves made, or by playing on-line, where both mobile telephones in such an instance are connected to each other and exchange information. Today, it is known to play on-line games via the Internet, either directly against each other or via a games exchange in a server. The switch 144 is toggled down and another player is thus chosen. Fig. 22c shows the name and number of the player marked. If a player toggles down he can choose to play against several players at the same time. Here, the choices shown should not be limiting for the actual idea regarding this part of the present invention. When a player has been selected, the game board will be shown on the display 145, as indicated in Fig. 22d.

In Fig. 22d, the players can be fetched from a permanent list of names, or possible letters are shown, making it easy to retrieve identifiable earlier co-players.

Fig. 22e shows the chess board where one of the squares is marked with the reference numeral 146. The cursor, which is indicated by the reference numeral 146, can be moved over the board and the pieces by toggling the switch 144 in the desired direction. In this case the cursor is placed over a white pawn. To confirm the chosen piece, the player presses on pressure point I to confirm OK. When the player then toggles, the piece will accompany the toggling movement, as shown in Fig. 22f. When the player has then positioned the piece, he can press once more on the pressure point I for OK and confirm the position of the piece.

Another alternative for positioning the piece is, in given fields, such as the field 147, to enter the existing position of the piece and in the field 148 to enter the coordinates of the field to which the piece is to move. This solution may be appropriate if a toggle/rotation/sliding/joystick function is not available, and especially in connection with apparatus that are equipped with an ordinary keyboard or keypad. Fields with reference to the movements of the pieces (from/to) are shown on the display 145, like the said fields 147 and 148. As shown in Fig. 22g, the function field 149 will show the letters and numbers required for the coordinates that are to be entered. Here, on the selection of II the letters D, E, F will be split up and the letter D selected by depression of the control element 144 at position I. Numbers will then be shown in the function field, as can be seen from Fig. 22h. This will then be repeated cyclically to complete the from-to determination. When the coordinates have been entered in the fields 147 and 148, the bottom field 149 will change function and the player can enter OK/send if the move has been made. Alternatively, the player can press down at the depression point IV to return and choose another chess move. A menu for the game and/or other functions which will be necessary during the game, e.g., "I give up" can be installed under "shift".

When OK/send is selected, the chess move is transmitted to the opponent or opponents. The recipient's apparatus will thus activate the game function which finds chess and shows the chess move that has been transmitted from the sender to the recipient.

Figs. 23a-23f show how it is possible to control a chess games by using a rotary switch 150, shown here having four depression points I, II, III and TV. Fig. 23a shows an image where the white player has moved to D4. It is the black player's 152 turn to play, and this is indicated by highlighting the field 153 or marking it in some other way, for example, by writing "playing" to show which player is now active. Movement of the pieces takes place as described below.

In the screen image, a field for "from" is indicated by the reference numeral 154 and a field for "to" is indicated by the reference numeral 155. When the players have activated the game, the field 154 will be marked, and when the multifunction switch control element 150 turned, a cursor 156 will move over the letters which define the coordinates for the X direction. To choose letters, the user depresses depression point I (OK). When this has been done, the system will automatically activate rotation of the switch for movement of the cursor 157. To select numbers for the Y coordinate, the control element 150 is rotated until a desired number is marked. To confirm this selection, the player presses on the point I (OK function) on the control element 150.

In Fig. 23a the field 154 is marked, ready for entry of coordinates for the selection of a chess piece. In Fig. 23b the control element 150 is rotated and the letter d is selected. As indicated in Fig. 23c, the control element is rotated once more and the number 7 is selected. This gives coordinates for a black pawn D7, which in this case is highlighted or marked by the marking 158, see Fig. 23c, so that the number 7 is selected. After the chess piece has been selected, the cursors 156, 157 will return to their starting position, as shown in Fig. 23d. The field 155 will now be marked and it will now be time for the player to decide where the selected piece is to be moved. Fig. 23 e shows the selection of coordinate D5, and the cursor 158 will thus automatically move to the selected coordinate. By pressing down at point I on the control element 150, the OK function is confirmed and thus the chess move, and the piece is moved at the same time as the opponent "is activated".

Another aspect of the present invention will now be described as a supplement to that which was shown and described in connection with Fig. 13. Reference will now be made to that shown in Figs. 24a and 24b, and Fig. 27. As anyone who has used a mobile telephone knows, a mobile telephone cannot be switched on at all times, as for instance during a plane journey or in areas where there is a danger of triggering explosions or affecting electronic equipment, such as in a modern hospital. Modern mobile telephones and similar apparatus having a radio part are beginning to have a vast number of functions that do not require logging on to the telephone network, as for instance games, calendar, write functions etc. Many of the multifunction switches shown in the present application and in the Applicant's earlier applications could control apparatus without the addition of surrounding switches.

The switches described in the present application, among others, are made so that they can be used to operate all types of applications. The use can be made either in connection with remote control or by using several functions in one and the same apparatus, as shown in connection with Fig. 27 where the reference numeral 159 indicates a typical multifunction apparatus with a multifunction switch 160, and where the reference numeral 161 indicates a typical remote control unit with a multifunction switch 162 and a display 163. The multifunction apparatus 159 with its display screen 164 and the switch 160 may be connected to, for example, a PC 165 or optionally to a television set 166, or the remote control unit 161 may effect control of functions in such a PC or television set. In connection with the operation in the multifunction apparatus 159, there may be a large menu as indicated by the reference numeral 167. For a more detailed explanation, reference will now be made to Fig. 24a and Fig. 24b which show a stepwise movable sliding or push switch 168 which is interactive with a display screen 169 on which different functions and programs are shown in X and Y positions. In this connection, reference is also made to that shown in Fig. 27 for simplicity. In position XI, Yl a games function 170 is shown. In position XI, Y2, a drawing function 171 is shown, optionally with a sketch book function 172 (this last-mentioned is not shown in Fig. 24). In position XI, Y3 there is a music playing function, e.g., CD/MP3, indicated by the reference numeral 173. In position XI, Y4 there is a WAP/Internet connection indicated by the reference numeral 181. The coordinate XI, X5 shows a telephone function indicated by the reference numeral 175. Position X2, Yl indicates a calculator function defined by the reference numeral 176. Position X2, Y2 indicates a photofunction 177. X2, Y3 indicates a film option 178. X2, Y4 represents an FM/AM radio function indicated by the reference numeral 179. X2, Y5 may be connected to a GPS function, as indicated by the reference numeral 180. The X3, Y2 function may be connected to books as indicated by the reference numeral 174. X3, Y3 may be related to a TV connection as indicated by the reference numeral 166 in Fig. 27. X3, Y4 may be related to an Internet connection or connection to another network, symbolised by the reference numeral 181'. X3, Y5 may be related to calendar/diary, indicated by the reference numeral 182. On the apparatus 159 there is a function related to connections and apparatus on/off, indicated by the reference numeral 183 in Fig. 27.

How it is possible by means of the control element 168 of the push switch, optionally a rotary switch, to operate the different functions has already been shown and described per se in connection with, e.g., Fig. 13, and so it should not be necessary to describe in more detail how it is possible to select functions. However, it is important to note that on use of the control element 168 of the multifunction switch, it will be possible to cut out, e.g., on board an aeroplane, the functions that are associated with radio-related functions, such as the functions related to the coordinates XI Y4, XI Y5, X2 Y4, X2 Y5, X3 Y3 and X3 Y4. On the transition from use of the other, non RF signal-related functions to the said RF signal-related functions, an extra deactivation of the RF signal blocking function might be required, e.g., in that on depression of the multifunction switches 168 at depression point IV, a field is generated on the display screen 169 which necessitates entry of a personal code in order to be able to reactivate the said RF signal-related functions. An extra image of this kind is not shown in Fig. 24, but it will be understood immediately, for example, with reference to that shown in Fig. 5, how the input of a code can be made possible. In the solution outlined in Fig. 24, it will be appreciated that a function apparatus could be used without the radio part being connected. Thus, it will be possible, for example, to write messages that can be stored for transmission once connection can be made or is allowed.

An apparatus as outlined above can of course also be operated using switches as shown earlier in this description and in the drawings. Figs. 25 and 26 show roller switches in the form of a configuration where the switches are placed in a cross formation. Fig. 25 shows how, in connection with a drawing function XI Y2, a multifunction switch of this kind can be used for navigation in a three-dimensional drawing program, as indicated in Fig. 25b. By having in this case three rotatable roller switches 184-186, it is possible, as already shown and described, to navigate in the X, Y and Z dimension. By using a roller switch combination of this kind, where there is the possibility of a total of five depression points in addition to the roller switch function, it will be understood that there will be means for controlling a cursor, object, view, tools etc. three- dimensionally. A command such as "zoom" would be a natural command to use as a standard for a third rotatable switch. A switch of this kind could also be advantageous in connection with a two-dimensional drawing program.

Fig. 26 shows an example of how it is possible to control a car game, initiated by selection of the function field XI Yl. Here an uppermost rotatable switch 185 can be used as a steering switch and the lowermost 186 as a "zoom" switch. In addition, it is possible by following the principles as described earlier to assign different functions to where it feels appropriate in order to obtain simple control of the game.

Another possible variation for making changes in a program is shown in a purely general manner in Fig. 26 and it is not intended to go into more detail. Fig. 26d shows a variant of the solution in Fig. 26c, where a standard rotary switch having depression points is used to steer, e.g., the car that is part of the game. The depression point I can for example, set the speed, depression point II can set what the image will look like and depression point III can be related to a braking function, e.g., to brake the speed of the car shown before bends etc. In actual fact, the multifunction switch, rotatable in both directions, can be used in connection with a steering wheel function to steer the car in the landscape of the game.

That shown in Fig. 27 does not require a fixed wire connection, as the transmission of signals between, for example, the multifunction apparatus 159 and the television set 166 or the PC 165 can take place wirelessly. The same applies to the remote control unit 161.

The invention will now be explained further in relation to Figs. 28a and 28b. The figures show how a roller switch 187 with three pressure points and sideways movement (toggle function) can operate relative to a remote image. Fig. 28a shows navigation in/of a text. The cursor is moved in the Y direction on rotation, and in the X direction on sideways movement of the switch in an axial direction. The pressure positions I-III relate to the fields indicated by the reference numeral 188, i.e., XI, X2 and X3. This field 188 will provide possibilities for changing the functions of the switch. In Fig. 28b the switch is used in a mode where it navigates pages in the X and/or Y direction, e.g., text, web pages, directories etc. Fig. 29 shows the switch illustrated in Fig. 28 with the addition of two rotatable roller elements 189. 190, and the function of this is explained in more detail in connection with Fig. 30 below. In this solution, however, the roller switch 187 is movable in its longitudinal direction and will therefore be able to have functions added for control of movement on the screen or direct command in connection with input or other functions in an application and/or in a program.

Figs. 30a-30d show roller switches arranged in a cross configuration. These figures show a roller switch 191 with a roller switch 192 mounted transverse to the working direction of the switch 191, but flush with the centre of the switch 191, i.e., the pressure point II. The switch 192 can be tilted or pressed to obtain a fourth pressure point IV. The switch 192 will essentially be capable of controlling navigation in the X direction, whilst the switch 191 will control navigation in the Y direction. Another rotatable roller switch 193 is provided, which is preferably depressible or tiltable and located on essentially the same axis as the switch 192, but "below" the roller switch 191. This means that another pressure point V is obtained, and a third possible rotation, e.g., in the Z direction, e.g., for provision of zoom functions. The function fields represented by the reference numeral 194 relate to the pressure points I-III, and the global fields 195, 196 relate to the respective pressure points IV and V. Fig. 30c shows an alternative embodiment where the global fields, indicated by the reference numerals 195' and 196', are located respectively at the top and the bottom of the screen image. By rotating the roller switches 191-193 it will be possible for a user to gain direct access to navigation in the X, Y and Z direction, as indicated in Fig. 30d.

Fig. 31 shows a switch embodiment like that shown in Fig. 30, but where the switch assembly has been rotated 90°. The switch 191, indicated in this figure by the reference numeral 191', is vertical and will control a cursor, the screen image and other movements in connection with screen use in the X direction. The depression point I-III will relate to the fields 194, 195 and 196. The roller switch 192' will on rotation control Y functions. By depression on depression point IV on this switch, the field 197 will be activatable. The depression point V on the roller switch 193 will control the field 198. The fields 194 and 196 may be regarded as so-called global fields, whilst the fields 197, 195 and 198 can consist of traditional XI, X2 and X3 related fields. Fig. 31b shows that by rotating the switches 191' and 192' it is possible to control a cursor over a screen image, e.g., for the selection of functions in a menu. Figure 31c shows an alternative arrangement where the global fields 194 and 196 are indicated respectively by the reference numeral 194' and 196' and located respectively at the top and the bottom of the screen image.

Figure 32 shows a solution in which the roller switches 192 and 193 are located on each side of the roller switches 191. In this embodiment the roller switches are indicated by the reference numerals 191". 192" and 193". The rollers 192" and 193" will control the functions as given in connection with Figures 30 and 31. Fig. 32b shows a switch solution with just three pressure points, which relate to the fields 199, 200 and 201, respectively. Unlike that shown in Figure 28, this switch has three possibilities for rotation and thus provides direct navigation in the x, y and z direction. In this illustrated solution, the centre roller switch, indicated by the reference numeral 191'", has only one central depression point.

Fig. 33 has been included to show the possibility of a switch where there are three independent rotatable elements 202, 203, 204 in the form of roller switches, and where there is a total of five depression points in the switch assembly. Figure 33 is shown in connection with this drawing program. The system for depression and rotation has been described in connection with, inter alia, Fig. 30 and it should not be necessary to repeat this description here. Fig. 33a shows an opening arrangement for, e.g., a drawing program. The fields 205 shows a selection of commands that are available on the display 206 and that can be activated by presses on the pressure points I, II or III. The global fields 207 and 208 are related to the depression points IV and V and are controlled via top-level main commands. If, for example, depression point II is selected, "new" is activated to start a new drawing. In Fig. 33b it will be seen that the field 205 has changed, and "tools" is selected by a further depression of the depression point II. Rotation of the roller switches 202 and 203 will enable the cursor 209 which appears in the screen image to be navigated over the options shown, in this case tools for drawing. The option in the field 210 and 205 can be shifted by pressing on the depression point V "shift". Here, tools can be selected for a pen by the depression of depression point I in connection with the field 210, see Fig. 33d. Rotation of the switches 202 and 203 and a press on the depression point I to confirm a drawn line, OK, will enable the drawing operation to be carried out. For additional functions, "tools" can be selected, see Figure 33e, and these are shown in the field 210, see Figure 33 f. As explained earlier in connection a function/tool is selected here, for example, "extrude", which means to make a three-dimensional shape on a two-dimensional drawing. Figure 33g indicates that it is desirable to change the view or perspective. Here, a function for this can be installed in connection with the roller switch 204, the depression point V. The fields indicated by the reference numeral 205 will change, so that the different views are changed. In the present example, the depression point I is selected and perspective will appear in the field 210, see Figure 33i. Rotation of the roller switch 204 will cause the size of the illustration to be changed (the zoom function as indicated in Figure 33j). Here, it is also possible to press on the pressure point V so that the "shift" function is activated and the field 205 will thus be altered for new options, so that, for example, the pressure point II can be depressed, whereby rotation can be carried out by rotating the roller switches 202 and 203, so that, for example, a display as indicated in Figure 331 is obtained.

The example shown in Figure 33 should not be regarded as an absolute solution, but is merely intended as an introduction for the skilled person as to how multifunction switches of different character can replace ordinary keyboards or keypads. The example shows in fact how it is possible to control advanced programs by using just one multifunction switch solution. The skilled person with a sound knowledge of programming software for control units could easily make variations of the possible uses that are shown by way of example in the present application.

Figure 34 shows the combinations of a roller switch 211 and a ring-shaped rotary switch 212. In this figure a combination is shown where the roller switch 211 has possibilities for sideways axial movement. This permits a cursor in, for example, a text to be moved, and at the same time the rotary switch 212 can be used to scroll up and down pages, or can be used for a zoom or enlargement function. The pressure points I, II and III relate to the respective fields 213, 214 and 215. Figure 35 shows a solution in which the roller switch, indicated by the reference numeral 216 has only one depression point, indicated by the reference II, whilst the other depression points indicated by I, III and IV and V are related to a ring-shaped rotary switch 217. The depression points I, II and III are related to the fields 218, 219 and 220 and the depression points TV and V are related to the fields 221 and 222.

On rotation and movement of the roller switches 216 and 217, it will be easy to effect navigation of a cursor on the screen, movement of the screen image, size adjustment etc.

Figure 36 shows a switch solution which can be seen from figures such as Figures 30 and 33, but with the addition of a ring-shaped rotary switch like the rotary switch 212 shown in Figure 34. The rotary switch 212 in this case can be used for scrolling up and down pages, whilst the switches 191, 192 and 193 can navigate per se like the switches 202, 203 and 204 shown in Figure 33.

Figure 37 shows a modification of the solution shown in Figure 36 where the ring- shaped stepwise movable rotary switch is indicated by the reference numeral 223 and is provided with a total of four depression points indicated by the references VI, VII, VIII and LX. Thus, in this case a total of nine depression points will be provided, and the selection field, indicated here by the reference numeral 224, will have a total of five sub-fields which are related from left to right to the depression points VI, I, II, III and VIII. The fields 225, 226, 227, 228 are controlled respectively by depression points TV, VI, V and VII.

Figure 38 shows an example of how it is possible to work in a program and how, by using the multifunction switch, the user can work with several functions without having to close the programs in question. Figure 38a shows a positioned cursor 229 in a text field, where the function field 230 shows letters for input by using the depression points I-III according to the system solutions previously described. When pressure point V on the roller switch 234 is pressed, the function "shift" will be activated, and the field 230 will change functions. Here, as shown in Fig. 38b, depression point II is chosen and the program is minimised, but the text program will however not be switched off, but is marked in a screen field 231, as shown in Fig. 39, to indicate that the program is on. Here, a new function can be selected by navigating with the roller switches 232 and 233 in the x/y direction. By rotating the roller switch 234 it is possible to zoom in the screen image. As a ring-shaped rotary switch 235 can also be rotated, it will be possible to move the screen image in a y direction. To change direction, the user can depress at pressure point V in this mode ("shift" function).

In Figure 40 it is shown how it is possible to divide navigation between the different switches. Here, as an example movement of a three-dimensional figure is shown. Rotation of switch 237 initiates the turning of the object in cooperation with the rotation of the roller switch 236. Rotation of the roller switch 238 initiates navigation of the screen image in x-y direction, i.e., up/down, right/left. By rotating the ring-shaped rotary switch 239 it is possible to provide a zoom function, as shown in Figure 40c.

Figure 41 shows a roller switch solution with a roller switch 240 which allows a cursor 241 to be moved in the y direction. The whole switch solution can be turned, as shown in Figure 41b to a position as shown in Figure 41c where the cursor after a 90° turn of the roller switch 240 can be moved in the x direction on rotation of the switch 240. In other words, by rotating the roller switch about its axis, it is possible to control the cursor in one direction, whereupon on a 90° axial turn of the switch the cursor can be controlled in another direction. Figures 41d-41f show that in a predetermined mode it is possible to rotate the whole screen image so that it follows the "geographical directions" of the switch. This may be an advantage when it is desirable to have an apparatus where it is possible to have individual settings for how the user would like to use such an apparatus. Thus, turning the roller switch 240 in a clockwise direction to a position as shown in Figure 41 e causes the image displayed to change from "portrait mode" to "landscape mode", as shown in Figure 41e and Figure 41f.

Figure 42a and Figure 42b show how even when a roller switch 242 is turned from a horizontal position to a vertical position, it is possible to allow the surrounding four pressure points 243, 244, 245 and 246 in effect to remain in the same place regardless of whether the roller switch 242 is in a horizontal or vertical position. The roller switch 242 will thus have a depression point 247. It will be seen immediately how these depression points 243-247 are related to the respective fields 248-252.

A variant of that shown in Figure 42 can be seen from Figure 43. The solution in Figure 43 must also be regarded as a variant of the solutions shown in Figures 35 and 37. In Figure 43a there is a central rotary switch 253 that is a roller switch with three depression points. This roller switch is, as shown in Figure 43, rotatable to a vertical position. The roller switch 253 is surrounded by a ring-shaped rotary switch 254. The rotary switch 253 has three depression points 255, 256, 257 and the rotary switch 254 has four depression points 258, 259, 260 and 261. In the position of the roller switch 253 shown in Figure 43a, five depression points are obtained 258, 255, 256, 257 and 260 in the x direction, which is reflected by the five function fields in the field area 262.

When the roller switch 253 is turned 90° into the vertical position given in Figure 43b, the screen image will change to match the location of the pressure points which are then present. It will be seen in this figure that there are then five pressure points in the y direction, and these pressure points, represented from the top to the bottom by the pressure points 261, 257, 256, 255 and 259, will respectively control the five sub-fields 263, 264, 262', 265 and 266. Similarly, in Fig. 43a, the pressure points 261 and 259 will control the fields 263 and 266. Fig. 44a shows a five-press multifunction switch 267 that is stepwise rotatable and has depression points indicated by I', II', III', IV and V. An animation 268 of such a switch can be shown in a screen image on a display screen 269, so that the user does not need to look at the switch in order to operate it, but can simply watch the animation.

Fig. 45a shows a five-press multifunction switch 270 which is stepwise rotatable and has depression points indicated by I', II', IIP, IV and V, but which differs from the switch 267 in that in the centre of the switch there may be an extra control element 271 which provides an extra function or can replace a centre click on the switch. The control element 271 is related to a centre position deviation and operates in such a mode as a control means for a cursor 272. An animation 273 of such a switch can be shown in a screen image on a display screen 274, so that the user interactively operates the switch and its functions just be watching the screen.

Figs. 46a-46d show what the screen image 275 on a multifunction apparatus may look like. Here, reference is also made to Figs. 24 and 27. By using the centrally arranged control element 271, it is possible to move the cursor 272 and confirm the selection by depression of the control element 271 and activation of a switch function. However, confirmation by depression of one of the points I', IIP, IV and V on the rotatable control element 271' is also conceivable. Fig. 46b shows a screen image for selection of a telephone function. Here, the screen area is shown containing animation 276 of the switch 270, where the animation actively shows what the switch represents. A central click or central press on the control element 271 of the switch moves the system back to the main menu, as shown in Fig. 46a. The switch assembly is made so that the central control element 271 (central switch) will function as an ordinary pressure-operated switch in most situations, but will in some menus activate movement of a cursor or pointer 272.

Fig. 46c shows a pointer 272 in connection with another screen image 277, where it will be seen that the central control element now has a pointer function, whilst a telephone function is present. In Fig. 46d the system is shown in connection with a calculator function with a screen image 278. The pointer 273 is moved to the desired field of the functions fields on the screen image and confirmation is effected by depression of the element 271. The encircling element 271' is adapted to select, on selective depression, e.g., one of the functions "Menu", "Scienf (scientific function), "INV' and "Close". Cursor 272 is movable in the X and/or Y direction on the display screen. The multifunction switch 270 thus has the centrally arranged, first control element 271 that is non-rotatable, but radially displaceable relative to its centre position in order to be able perform centre position deviation based mouse function for control of the cursor or pointer 272, and on depression to be able to perform a switch function. The second, stepwise rotatable control element 271', which encircles the first control element 271, will be capable of effecting movement of the cursor 272 in an particular direction in a menu image. As indicated above, the second control element 271' is depressible at four depression positions in order to actuate a respective switch function connected to the menu image.

Although it is possible, it is of course not necessary to have an animation of the switch in the screen image all the time, and the system is therefore so designed that in at least one menu it reproduces on the display screen an animation of the possible manipulations of the multifunction switch. In connection with a given menu image, the system will be able to selectively determine in accordance with a given program whether the first control element 271 has a mouse function (pointer function) or depression-based function. It is also possible that both parts may be present, namely pointer function with the possibility of confirming depression. Thus, in said step position of the second control element 271', the menu-related function which a depression or centre position deviation of the first control element will activate is reproduced.

Figs. 47a and 47b show input of a telephone number in a telephone mode. On rotation of a switch 267, as shown in Fig. 44a, or switch 270 as shown in Fig. 45a (where the non-rotatable, central control element in the illustrated example has not been given a centre position deviation function), the rotation of such a switch, in Figs. 47a and 47b indicated by 280, will cause the cursor field 281 to move over the numbers, and the numbers will be activatable by a press on a selected one of the depression points IV, I' and V shown on the switch animation 279 for the selected cursor position. When the telephone number has been entered by successive input, as shown in Fig. 47b, OK is pressed, i.e., depression point III' is pressed, and the image shown in Fig. 47b appears. Further operation of the switch 280 will enable a desired telephone mode or clear and return to the menu to be chosen.

Fig. 48a shows the selection of the WAP function in the main menu for a telephone, where a switch of the type shown in Fig. 45 a can advantageously be used. When OK as shown in the animation 282, i.e., depression point III' on the switch 270, is pressed, the central control element 271' will change character to a centre position deviation function as shown in Fig. 48b, symbolised by II' and the reference numeral 283 and will thus be able to control a pointer 284.

Figs. 49a-49h show the use of a rotatable pressure-operated switch 285 of essentially the type already shown and described in connection with Fig. 44a, but in this case only four depression points I', II', III' and IV are shown, of which IV can be used for a return and/or clear function. The depression points I'-III' correspond to the fields I-III. Here, three fields at a time will be marked by a cursor 286 and can be moved, e.g., up or down, by rotation of the switch 285, as explained earlier. In the illustrated example, icons related to a menu are shown. When the point III' is depressed the icon at position III will be marked as indicated by cursor 287 and selected, whereupon a sub-menu will appear as shown in Fig. 49c, the selected icon being related to Messages. Here, as shown in Fig. 49c, there are additional icons linked to the sub-menu, and when the cursor 288 is placed on the three uppermost icons and depression at the point I' is made, the cursor 287 will mark the icon for the "Write" function and effect a transition to the sub-menu as shown in Fig. 49d, where the alphabet appears on the screen in groups of three letters and can be split according to a pattern previously shown.

Fig. 49h shows a situation where the whole alphabet is pre-split. However, this will require considerably larger screen space to be able to show as much as that shown in groups in the preceding figures.

When a function has been selected, the system thus provides a display on the screen of at least three sub-function options, or at least three possible sub-functions in each step of a set of steps. For the selection of a sub-function in one of said steps, the step is selected as indicated by rotation of the control element, and the sub-function in the step is selected by depression at the desired depression point, or optionally sideways tilting if a switch as shown in Fig. 63 is chosen, or by axial displacement of the control element if a switch as shown in Fig. 67 is chosen.

When a sub-function has been chosen by activating the control element, the system is designed to show at least three sub-sub-function options in each step of a set of steps. It is also possible that when a sub-function is selected, the sub-function is designed to be adjusted whilst displayed on the screen by stepwise rotation of the control element. In a similar manner as that employed to select a sub-function, for the selection of a sub- sub-function in one of the possible steps, a step will be selected on rotation of the control element, and the sub-sub-function is chosen by depression on the desired depression point, optionally by sideways tilting or axial displacement of the control element as mentioned above when another type of switch is used. When a sub-sub- function has been selected, the sub-sub-function is designed to be able to optionally be adjusted whilst displayed on the screen by stepwise rotation of the control element.

As shown and explained above, when a selected icon or symbol represented function, sub-function and/or sub-sub-function is shown on the screen, the system is designed to show on the screen a highlighting or marking thereof. In addition, at least some of the functions, sub-functions and/or sub-sub-functions are also described on the screen in a text, see, e.g., Fig. 49c.

The selections made in a function, sub-function and/or sub-sub-function one or more times are reproduced in a separate display field on the display screen, as shown for instance in Fig. 49g after depression at the point II' for selection of the letter T as shown in Fig. 49f. Figs. 50a-50h show the situation where an apparatus has a small display screen, which is typical for, e.g., small mobile telephones. Fig. 50a shows a main menu and Fig. 50b shows a sub-menu, and Figs. 50c and 50d show a sub-sub-menu.

Depression of the switch 289 at the depression point I' generates a sub-menu as shown in Fig. 50b, and selection of the sub-menu for telephone numbers (?Number) will generate a sub-sub-menu as in Fig. 50c, whereupon the telephone number can be entered by moving the cursor 289 up or down by rotation of the switch, and by depression of one of the depression points I'-III'. As soon as the telephone number has been entered, as shown in Fig. 50d, the cursor can be moved down to a lower area for selection of a function. It is also possible that the lower area could be marked automatically by the system for selection therein as soon as, e.g., the digits of a telephone number are shown with the desired number.

Figs. 50e-50h show how in fixed fields data , e.g., for the setting of time and date, can be selected. The cursor 290 is moved by rotation of the switch 291 to the desired step area on the screen image. The desired sub-field of the fields I, II, III is selected by an accompanying depression of switch 291 at one of the given points T, IT and IIP, in the case shown II'. Three options may then appear on the screen as shown in Fig. 5 Of. These options can either be on a line as three fields, or the switch can be rotated to select the desired field, whereupon the switch is depressed, e.g., at one of the depressions points, or at a central point on the switch, if there is one, to choose the desired sub-menu. When the sub-menu, as for instance "SetTime/Date", has been selected, an image, for example, as shown in Fig. 50g is generated. Selection of fields containing sub-fields which are to be selected and adjusted is found on rotation of the switch and selection by depression on one of the depression points I'-III'. Once a field has been selected, e.g., time, and then a sub-field, e.g., hours, minutes, seconds, is selected, the rotary part of the switch is used to rotate through, e.g., 0-24 hours, 0-60 minutes and 0-60 seconds respectively. Movement to the next field and in this sub-field means that what has been left in the individual sub-field becomes valid as soon as the cursor 292 is moved to the lower position and depression is made at IIP (OK). Alternatively, after a sub-field has been adjusted, it may be possible to confirm the adjustment by depression of the switch, whereupon a return is made to the screen image in Fig. 50g for selection of a new field on rotation of the switch 291 or to select another sub-field within the cursor.

Figs. 51-54 show an interactive system which includes a multifunction switch 293 (Figs. 51 and 52) or 294 (Figs. 53 and 54), a display screen 295 and a cursor 296 or 297 which is movable in the Y or X direction on the display screen. The multifunction switch 293;294 has a stepwise rotatable control element for movement of the cursor stepwise over three options at a time in a particular direction in a menu image, in Figs. 51 and 53 in the Y direction and in Figs. 52 and 54 in the X direction.

In a selected step position of the cursor, the control element may be depressible at one of three depression points I', II', IIP thereof as shown for the element 293. Alternatively, the control element in a selected step position of the cursor can be depressible at one of three depression positions or axially displaceable in order to actuate a respective switch function associated with a function among said options, as for the switch 294 (see also Fig. 62). Optionally it may be of a type as shown in Fig. 63 which is tiltable to one side or the other or centrally depressible in order to actuate a respective switch function associated with a function among the options.

In Figs. 55-57 the system is designed to show an n x m element matrix 298; 299 of menu-related function elements where n is related to a first direction and m is related to a second direction in the matrix. The multifunction switch, e.g., of the type shown in Fig. 55 and indicated generally by the reference numeral 300 or that indicated in Figs. 56 and 57 by the reference numeral 301, is designed for movement and positioning of a cursor stepwise over three options in the matrix at a time in a first direction in the matrix (e.g., the X direction) and/or in the second direction (e.g.-, the Y direction). In Figs. 51-54 the cursor was movable in one direction only (the Y direction for the embodiment in Figs. 51 and 52 and the X direction for the embodiment in Figs. 52 and 54). The multifunction switch is, on the use of its control element 300'; 301' and respectively depression points T, IT, TTT thereon in a selected step position of the cursor, designed to effect selection of one of said function elements then marked by the cursor. In Fig. 55 rotation of the control element 300' will effect stepwise movement of the cursor 302 in the Y direction, whilst use of keys 300" and 300'" will cause the cursor to move one way or the other in the X direction. In Fig. 56 the multifunction switch 301 will when rotated, move the cursor 302 one way or the other in the X direction, whilst depression of the switch at IV or V will move the cursor in the Y direction. Similarly, in Fig. 57, the multifunction switch 301 will when rotated move the cursor 303 one way or the other in the Y direction, whilst depression of the switch at IV or V will move the cursor in the X direction.

Figs. 58a-58d show by way of example how the system could operate stepwise, e.g., with a multifunction switch 300. In Fig. 58a the cursor is in position X10 X12; Y3. On depression of key 300" as shown in Fig. 58b, the cursor 302 is moved stepwise to position X8-X1+0; Y3. The control element 300' is then rotated one step so that the cursor 302 comes to position X8-X10; Y2, as shown in Fig. 58c. Then sub-field X9; Y2 with accompanying function element is selected by depression of the control element 300' in the central position II'. This last operation will be able to effect display of either p selectable sub-function elements in a first direction, such as the elements xl, x2, x3, x4, x5, x6, x7 as shown in Fig. 58e, or a sub-function matrix consisting of p x q selectable sub-function elements, e.g., of a type shown in Fig. 58a, where p is related to a first direction in the matrix (e.g., the X direction) and q is related to a second direction (e.g., the Y direction) in the matrix, with three sub-function options in each step of a set of steps. The multifunction switch will of course operate in the same way as described above in connection with Figs. 58a-58d. If the final display is as shown in Fig. 58e, rotation of the element 300' will have no effect, whilst the keys 300" and 300'" will be able to move the cursor 304 in the X direction. Depression of the element 300' at one of the points I', IP, IIP will determine which of the marked sub-fields xl-x7 can be selected.

When a sub-function has been chosen by activating the control element, the system is designed to show at least three sub-sub-function elements, as indicated in, e.g., Fig. 58e. Although Fig. 58 shows by means of example n= 12 and m = 3, in purely general terms n 4 and m 2. For the sub-function array or matrix or sub-sub-function array of matrix in Fig. 58e p = 7 and q = 1 is shown, whilst usually in purely general terms p 4 and q 2 when a real matrix is involved.

That shown in Fig. 58 has relation to that shown in Fig. 59, where a matrix of n x m matrix 305 of menu functions symbolised by icons is shown. Use of the switch 300 in relation to the cursor, here indicated by 306 is like that described in connection with Fig. 58. In the case illustrated here n = 5 and m = 4 , although this is to be regarded as a non- limiting example.

In Fig. 60 the display 308 is of a smaller type than the display 307 in Fig. 59. The display 308 is designed, in the illustrated case, to show one n x m matrix at a time where n=m=3. When the real matrix is larger, i.e., e.g., n=5 and m=4, the display screen will show only a part of the whole matrix at a time. Therefore, on movement of the cursor 309, caused by the parts of the multifunction switch which normally provide such cursor movement (rotation of the element 300' for movement in the Y direction and use of the keys 300", 300" for movement in the X direction, i.e., along the first or second direction with a view to moving into a part of the matrix which as of now is not shown on the screen, the system will ensure that the cursor does not wander outside the screen image shown, but that at least one of the columns of the matrix not shown, e.g., the column X4 or rows, e.g., row Yl, over which the cursor stepwise is intended to move instead is adapted to move stepwise into the showable screen image on the screen, whilst at least one column, e.g., column CI or one row, e.g., row Y4 in the matrix shown on the opposite side of the screen is caused to move out of the screen image.

Fig. 61 a shows another solution made possible by the invention, and especially useful in connection with a multiwindow system as indicated schematically in Fig. 61b. The system is designed to show an n x m element matrix of menu-related function elements where n is related to a first direction and m to a second direction. However, the matrix in this case is divided into a first area 310 and an area field 311, where said two areas are separated by a screen sub-image 312 on the display screen 313. The multifunction switch 314, e.g., of the type shown in Fig. 45, is designed for movement and positioning of a cursor 315 preferably over one option in the matrix at a time or a cursor 315' stepwise over three options in the matrix at a time in a first direction and/or in the second direction in the matrix. The control element that is a part of the multifunction switch is, in a selected step position of the cursor, designed to effect selection of the function element or one of said function elements then marked by the cursor. The illustrated switch 316 in Fig. 61a is to be considered as a preferred example, but can optionally be replaced by other suitable multifunction switches. The switch 316 has a central, non-rotatable, but centre position deviation actuated element 316' for control of a pointer 317 on the sub-image, and a stepwise rotatable element 316" for movement of the cursor in the X direction in respective sub-areas 310, 311. Depression at the depression points IV or V causes alternation between rows in the respective areas 310, 311 or jumping between the areas. If the cursor 315 optionally marks three sub-fields (three icons) at a time, selection of one of these will be effected by depression on one of the depression points P-IIP. If the cursor 315 in fact shows just one field, e.g., field 318, at a time, central depression of the element 316', for example, will be decisive for selection of such a desired field. One of the function elements, indicated here by the reference numeral 319, may be related to movement between superimposed function windows in the system. Also, in the system solution shown here when an icon- or symbol-represented function, sub-function and/or sub-sub-function shown on the screen is selected, a highlighting or marking of the function, optionally with additional description in text format will be shown on the screen.

Although in Fig. 61a the area 310 is shown with one row and the area 311 with one row, and with seven icons in each row, so that the divided matrix will have n = 7 and m= 2, in purely general terms n 4 and m 2.

Figs. 62-72 show various alternative multifunction switches that are useable with different ones of the embodiments that have been shown and described. The solutions shown in Fig- 67-72 are particularly suitable for use in connection with the solutions shown and described in connection with Figs. 51-61, but the solutions in Figs. 69 and 60, in particular, are useful with the solutions shown in Figs. 46-50. The solutions shown in Figs. 62-66 are to a certain extent useful for the solutions described in connection with Figs. 45-50 and 73.

Fig. 62 shows a roller-shaped control element 320 which is stepwise rotatable, and which has three depression points P-IIP for selective actuation of a switch function.

Fig. 63 shows a roller-shaped control element 321 which is stepwise rotatable and which has a central depression point 321' and sideways tilt 321", 321'" for actuation of a respective switch function. Fig. 64 shows a non-rotatable multifunction switch 322 with five depression points I'-V for actuation of a respective switch function.

Fig. 65 shows a switch 323 which is stepwise rotatable and optionally depressible for actuation of a switch function. A combination of the switch solution in Figs. 64 and 65 is shown in Fig. 73, where it is desirable to be able to combine, e.g., several menus simultaneously, or where it is found practical to have two switches. The switch 323 may optionally have four depression points I'-TV for actuation of desired switch functions, and optionally also a fifth depression point V. In the two last-mentioned cases, the switch has a multifunction capacity like that of the switch shown in Fig. 69.

Fig. 66 shows a multifunction switch 324 which is four-way tiltable and centrally depressible for actuation of respective switch functions.

Fig. 67 shows a roller-shaped control element 325 which is stepwise rotatable, and which has three depression points P-IIP for selective actuation of a switch function, and axial movability as shown by the two-way arrow 326 for actuation of two more switch functions.

Fig. 68 shows a roller-shaped control element 327 which is stepwise rotatable and which has a central depression point 327' and sideways tilt 327", 327'" for actuation of a respective switch function, plus two more keys 328 and 329. Rotation of the control element will move a cursor in one direction, e.g., the Y direction, whilst the keys 328, 329 will be able to move the cursor in the X direction.

The solution shown in Fig. 69 has relation to that just shown and described in connection with Fig. 65, but also that shown and described in connection with Fig. 44a and Fig. 47 and Fig. 49. The control element in Fig. 69 is indicated by the reference numeral 330.

The solution shown in Fig. 70 differs from that shown in Figs. 65 and 69 in that the multifunction switch 331 has a central first control element 331' that is non-rotatable , but displaceable from a centre position for control of a pointer or cursor, or menu- determined has only one depression point function V, and a second, encircling stepwise rotatable control element 331" and having four depression points I'-TV". Fig. 71 shows a multifunction switch 322 which is four- way tiltable and centrally depressible for actuation of respective switch functions. In addition, there are two switch function keys 333, 334 to be able to move a cursor in, e.g., the X direction. Alternatively, the switch 322 will be arranged to move the cursor in the Y and/or X direction whilst the keys 333, 334 together with a central depression point on the switch 322 will be able to effect selection of sub-fields from among three sub-fields marked by the cursor.

Fig. 72 shows variant of the solution shown in Fig. 67. A roller- shaped control element 335 is shown which is stepwise rotatable, and which has three depression points P-IIP for selective actuation of a switch function, and two switch function keys 336, 337 which serve, e.g., to move a cursor in the X direction.

Fig. 73 shows another multifunction switch which is useful with the invention and where this switch consists of an endless belt 338 which runs over the wholly schematically indicated rollers 344, 345 at each end of the switch, and where on depression of the belt 338 it is possible, via pressure points 339-343, to actuate switch functions in the switches which lie immediately beneath the belt and/or in connection with a cradle on which the belt and said rollers are mounted. Thus, the multifunction switch in this case is centrally depressible and depressible at its ends and on its longitudinal sides. The stepwise movement of the belt 338 one way or the other, and thus the rotation of the rollers 344 and 345, will have a function corresponding to, for example, rotation of the multifunction switch as shown in Fig. 65, i.e. rotation of the ring-shaped or disc-shaped element.

Fig. 74 shows an interactive system that is intended to operate interacting menus, submenus or sub-sub-menus 346, 347 displayed on a display screen 348. The position of the menus 346, 347 on the screen is randomly selected in Fig. 74, and any suitable configuration is of course possible. Naturally, the screen 348 may also have another configuration. A stepwise rotatable multifunction switch 323 is in this example supplemented by non-rotatable multifunction switch 322 and 324 formed by a four-way tiltable and centrally depressible control element for movement of a cursor stepwise over at least three options at a time in a particular direction in a menu image, the control element in a selected step position of the cursor being adapted to place the cursor in a desired one of at least three fields in said step, and on central depression to activate a switch function for selection of an associated function among said options. Attached Figs. 75-95 show additional solutions for interactive use of multifunction switches. The switches that are intended to be used for the following embodiments in an interactive system have three or five pressure functions. It will also be shown how the system can be used with a single rotating and one-point pressure-operated switch.

Figs. 75a-d show the use of a stepwise rotatable roller switch 350 having switch functions associated with three pressure points or one pressure point and two side tilting positions I, II, III. The screen 351 shows a menu represented by icons of different functions, in this case typically for a mobile telephone. As shown earlier, a cursor field 352 will be moved in the Y direction by rotating the switch. In each of the Y positions there will be three options XI -X3 which relate to the pressure positions I-III on the switch 350. In Fig. 75b the top field Y5 is chosen, and when the switch 350 is rotated to this position Y5 the cursor field 352 will move to position 352', and telephone function 354 is activated by pressing on the switch in position I and the screen image, shown in Fig. 75c, presents a number which can be selected by rotation of the switch for movement of the cursor 352" to, e.g., cursor position 352" and selection of the number by pressing as required on the switch 350. Fig. 75d shows the selection of the number 2 by pressing on II. In position Yl-Xl is the function "Back" 355 which on activation takes the user back to the previous screen image or menu. The Y1-X2 position, indicated by the reference numeral 356 is associated with a direct function, like making a call, confirming a function, or can be used as a link for sub-sub-functions. The Y1-X3 position, indicated by the reference numeral 357 will in this connection give links to additional data or functions.

Figs. 76a-d show the use of a stepwise rotatable rotary switch with switch functions related to three pressure positions I, II, III or one pressure position and two tilting positions I, II, III. Menu and function are the same as for that shown in Fig. 75. The switch has the reference numeral 360 and the cursor for movement in the Y direction has the reference numeral 362 and 362'.

Figs. 77a and 77b show respectively a stepwise rotatable roller switch 370 and a rotary switch 372 having just one pressure point , but with the addition of two side switches 374-374' and 376-376' which replace the pressure and tilting positions shown in connection with the switch solutions in Figs. 75-76, so that a total of three pressure points I, II, III is obtained. Rotation of the switches 370; 372 moves cursor 371; 371' in the Y direction. Pressure on I-III on the different switches activates functions related to column XI -X3. Fig. 77c shows an alternative where pressure points I and III are replaced by the rotary switch 378 shown in the figure, which has central switch depression point II, being movable in one X direction or the other for activation of switch functions by means of switches positioned at the pressure points I and III.

Figs. 78a-78e shows stepwise movable sliding switch 380 having switch functions associated with five pressure points or one pressure point and four tilting points. Switch 380 can either have fixed sliding positions or a toggle function (kick switch function) as indicated for the switch 380' in Fig. 78b, for movement of a cursor 382. I-III are related to X functions marked in cursor fields 382, 382' and 382" respectively. The points IV and V have fixed functions such as OK/Yes and Clear/Back. The number of Y positions should not be regarded as limiting, but will be related to the number of functions required by the apparatus or means in question that is to be controlled. Fig. 78c shows telephone function 384 selected at press I as given in Fig. 78d. A press on pressure point III gives a write function 386 as shown in Fig. 78e.

Figs. 79a-d show an example of a stepwise movable belt switch 390 which has switch functions related to five pressure positions or a total of five pressure and tilting functions I-V. The distribution of functionality is the same as that shown in connection with Fig. 78. Fig. 79a shows rotation of belt switch 390 for movement of a cursor 392 to position Y4 and where a press on position I gives a write function 394. Fig. 79b shows the alphabet laid out in three columns with three letters/symbols in each of the groups in each column. A press on I, II or III will effect selection of one 396 of the groups JKL, MNO, PQR, in this case the group PQR, (see Fig. 79c), which causes a splitting of the data in the group to P Q R distributed in each column, as shown in Fig. 79d, for direct selection of data by pressing on a chosen one of the positions I-III, here represented by I and the reference numeral 398.

Fig. 80 shows two examples of how a menu of icons 401 can be arranged on the screen. Field 400 shows at all times functions related to switches having up to five tilting/pressure functions as, e.g., shown in Figs. 88-92. Fig. 80a will be related to a switch having stepwise based rotation function, as for instance shown in Fig. 88, but it must be pointed out that all multifunction switches having switch-related functions associated with five positions for pressing and/or tilting, and a stepwise-based, detectable rotational and/or sliding function will be able to use the system. The icons 401 that are arranged in a virtual ring will be related typically to a stepwise rotatable switch, and the sub-fields indicated collectively by 400 relate to the pressure and/or tilting positions on the switch as follows: I for 402, II for 403, III for 404, TV for 405 and V for 406. This is in contrast to that shown in connection with figures such as Figs. 78 and 79 where the central pressure function II does not have a fixed function, whilst V does. However, this must be seen in the light of whether the user has a menu which can also be used by a multifunction switch having three pressure positions. The system in, e.g., Figs. 78-79 does not have at all times full display of the functions of all the switches as shown in connection with Fig. 80, but as shown in Fig. 78a, TV and V have fixed functions.

Fig. 80a shows sub-fields 405 and 406 here with top-level fixed functions, and on rotation and application of pressure on the position on the switch related to sub-field 406 will result in activation of a marked or highlighted function from the menu on the screen. The sub-fields 402-404 will be related to the display of selectable, but stepwise alternating data and functions which are, inter alia, shown in connection with Fig. 81.

Fig. 80b could be used by a roller, rotary and sliding switch as shown in, e.g., Figs. 88- 92. A menu as shown here is directly selectable by moving cursor field 407 in the menu image and pressing on the switch for selection of sub-fields 402'-404' which correspond to columns XI -X3 in the screen image. The sub-fields 405' and 406' thus have the same functions as the sub-fields 405 and 406 in Fig. 80a and the sub-fields 402'-406' are indicated generally by 400'.

Figs. 81a-81c show how the screen image has a field 410 which shows at all times the available options and functions the switch has, in this case a switch having pressure positions related to five pressure functions, and rotation or sliding function. Field 410 has sub-fields 411-412 which change on stepwise movement of the switch. The fields 414-415 have top-level fixed functions, but can change to different commands according to the functions that are controlled. Figs. 81a-81c show sub-field 415 as a directly selectable command, whilst in Figs. 81d-81g sub-field 415 is a command for an sub-sub-menu which, when chosen, distributes functions over all sub-fields in the field 410.

Fig. 82a-c show a screen display for use of a switch having a rotary function and pressure and /or tilt positions for three switch functions, as shown, inter alia, by the switches in Figs. 83-84. The screen 420 shows an example of functions which can be controlled in a means of transport. The screen shows a main menu 421 over which a cursor 422 can be moved by rotation of, e.g., rotary switch 430 or roller switch 431. The function that is marked will activate a sub-menu 424 for the function alternatives that are available. Central depression II on the switch (e.g., the switch 430 or 431) will lock the sub-menu to the main function so that a cursor 426 will be activated for movement in a sub-menu. Activation of sub-functions takes place by a press in position II on the switch. Fig. 82 shows activation of the ringing functions, i.e., dialling a telephone number. Field 429 will be active for selection of digits in the telephone number by pressing on respectively I-III on the switch for the input of numbers or signs from among 1 2 3, 4 5 6, 7 8 9 or * 0 #, which will then be placed successively in field 428 when activated. To return to the preceding menu 432, pressure point I is selected, to place a call 433, pressure point to is selected or to adjust volume 434 pressure point III is selected.

Figs. 85a-85d show an example of selection of an audio-function according to the same principle as that shown and described in connection with Figs. 82-84. Here a CD function 440 is selected which then gives the screen image 442. Activation of functions takes place by moving field 444 which is caused by stepwise movement of a multifunction switch, e.g., a rotary switch, and pressure on selected position I, II or III on the multifunction switch. Fig. 85d shows how Menu and sub-menu and options can be placed side by side if the screen areas so allows.

In connection with Fig. 86, a variant for organising functions on a screen will be shown. Typical mobile telephone functions are taken as a basis in this case. A switch that is suitable for use by the system is shown, e.g., in Figs. 77, 83 and 84. Fig. 86a shows a screen 450 which in an initial is divided into a menu part 451 and a sub-menu and/or function part 452. The main functions in the menu are shown as icons and represent in this case telephone function/place a call 453, name/address/telephone number 454, text messages 455, calendar/time 456, WAP/Internet 457, and an arrow for showing additional main functions 458. Stepwise movement of a multifunction switch, e.g., a rotary switch will in this mode mark one icon at a time. The function selected will be marked and a sub-menu/function will appear in field 452. Fig. 86b shows a situation where the telephone function has been chosen and the system shows a numeric keypad for input of a telephone number. The figure also shows that the multifunction switch has been activated for function selection which appears in field 452. Input is carried out in the manner described earlier in that a selected one of positions I-III is pressed on, and that cursor field 462 is moved over three data at a time on the step movement of the switch, i.e., a rotary switch. The reference numeral 464 indicates that the number 2 has been selected. To return to the preceding menu 466 depression point I is activated for a switch function associated therewith. If the user has finished the input of the number, "options" 467 is activated. Sub-field 468 ("Shift") is used for other functions during input. Fig. 86c shows an example where the function for text messages has been selected, indicated by the reference numeral 470. Input of letters, signs or symbols is carried out following the methods described earlier in this application, where each group of such data elements is selected by pressing on the switch-corresponding position of the positions I-III for splitting the group and selection of an individual letter or symbol in the split group.

In a display of functions represented by icons, there is always a danger that not all users will immediately understand what the icon means. In connection with Figs. 87a and 87b an example is shown of how a cursor field or highlighting field 476 can have a text function added where an explanation of each icon appears as the cursor is moved in the menu image.

The switches used for the described systems in this application are described technically in separate applications filed earlier by the Applicant and consequently are not described here. It must also be mentioned that the technical design of the multifunction switches that are intended to be used will not be of any importance for the system. Nevertheless it should be stressed that all the multifunction switches will advantageously be of a type that in a detectable manner can rotate stepwise rotate and/or be pushed or subjected to a stepwise sliding movement, and the switches therefore comprise means for this. The multifunction switches will also have positions thereon for activation by pressing and/or tilting and thus related switch functions, and the multifunction switches therefore have respective means for this.

In a number of the Applicant's earlier patent applications detailed designs of different types of multifunction switches are shown and described by way of example. These could advantageously be used in connection with the present invention, and a person of average skill in the field will, with the guidance of the present application, and the details given in the earlier applications understand how such multifunction switches can be used with the present invention.

Fig. 88 shows a stepwise rotatable disc-shaped switch 480 with five pressure positions, or one centre position and four tilt positions, where the positions are marked by I-V. The figure corresponds to Fig. 65, but has slightly different numbering as regards the positions concerned. Fig. 89 is a stepwise movable belt switch 482 with five pressure positions, or one centre pressure position and four tilt positions, where these are indicated by I-V. The switch consists of at least two rollers 482' and 482" with an endless belt 482'" therebetween and means (not shown) for detecting rotation, pressure and/or tilt functions. The figure corresponds to previous Figure 73.

Fig. 90 consists of a stepwise rotatable roller switch 483 in the form of a cylinder which can be pressed down at II and tilted at I and II, and of two juxtaposed pressure-operated switches 484 and 485. The solution can be used for a system that is suitable for use with, inter alia, a belt switch.

Fig. 91 shows a sliding switch 486 with five pressure positions, or one central pressure position and four tilt positions, where these are marked by I-V. The switch can either have a specific number of fixed stepwise sliding or push positions, or may be of such a type that is arranged to be pushed in one direction or the other in order to then return to a centre position (starting position), i.e., a so-called kick switch function.

Fig. 92 consists of a disc-shaped switch 488 which is detectably stepwise rotatable and which can be depressed centrally at position II and pushed in four direction for activation of contact points I and III-V. Reference numeral 489 shows arrows for indication of possible movements of the switch.

Lastly, there follows below a description of Figures 93-94.

Throughout this description and accompanying drawings there has been focus on systems which use multifunction switch solutions with a control element which in a detectable manner is stepwise movable. Either the control element is a rotatable disclike body or roller-shaped, or is a sliding switch, or is a sliding switch, or is a push switch, e.g., with the involvement of a kick switch function (toggle function), or is a belt switch, and where such a multifunction switch has at least three positions intended for depression and/or tilting for activation of a respective switch function. Thus, a multifunction switch of this kind will, as the only switch, be capable of controlling the system with its numerous possibilities for operating many menu functions in a simple and easy-to-follow way.

Examples of a combination of several switches to be able to perform the tasks the systems permits are also shown in the application. It should also be pointed out that these systems can be used by rotary, roller and belt switches, and one press switches to which reference will be made in connection with the description of Fig. 94. The stepwise movement of these switches is detectable. A known switch is outlined in Fig. 93 a, where the reference numeral 490 shows a stepwise, rotatable, disc-shaped switch having a central pressure position at I for activation of the switch function. Another known, stepwise rotatable roller switch 492 has a centrally located depression position I for activation of a switch function.

In Fig. 94a, it will be possible, by rotating the switch 490 or 492, to navigate up and down in the menu field 494 and by pressing at the position I to select a marked icon 496, see Fig. 94b. When sub-functions thus appear in field 498, rotation of the switch will effect movement of a cursor 500 along the path 502 shown in a dotted line by way of example in Fig. 94c. When pressure is applied to position I, data marked by the cursor will be activated/selected. Text/numbers and symbols will be shown in field 504 on successive continued input.

On the input of text, the user will have to move the cursor 508 over data groups, e.g., letters as shown in Fig. 95a, along a path 502', and where a selected data group is split as shown in Fig. 95b, here the group of letters GHI split into G H I. To enter the desired data element in the group, the switch 490; 492 is rotated among the various letters that are marked by the cursor 500' and confirmed by pressing on the switch in position I. When a desired letter has been confirmed there will be a return to the previous screen image and selection of a letter must take place via a new group selection. If a predictive system (which indicates possible "natural" next selection based in statistics, earlier data or composition rules, e.g., rules of grammar) is connected to the input, this system may be easier to use.

An important aspect of the invention is the possibility that , e.g., telecommunications operators, but also manufacturers of electronic equipment and associated software and hardware, can enlarge their menu systems without having to add extra operating buttons, and this also permits new functions to be taken into use without the user being confused as to which buttons must be pressed. Thus, any new function that is implemented in such equipment will be easy to operate, as it will be related to easy-to- perform stepwise movement of a multifunction switch, and pressure and /or tilt operation for control of associated switch function. For a user the pattern of use/mode of operation will in principle be known and logical.
