Definitions
- the present invention relates to handheld computers.
- the present invention relates to a handheld computer comprised of a moveable assembly that is adjustable to affect a size of the handheld computer.
- Handheld computers typically referred to as personal digital assistants (PDAS) are intended to be mobile devices.
- PDAS personal digital assistants
- small sizes are desired for handheld computers to enhance mobility.
- certain characteristics of handheld computers require a minimum amount of space on the exterior housing of the handheld computer.
- Most handheld computers require a minimum size display.
- the minimum display size is set by balancing considerations such as mobility with the need for the user to view data, such as personal management information, pictures, and text pages.
- the size of the display may also need to be large enough to provide a character input mechanism for the user.
- some handheld computers incorporate character recognition logic as a primary means for the user to enter character data into the handheld computer.
- the displays for the handheld computer may be made to be contact-sensitive. A portion of the display may be combined with logic to provide an immediate character recognizer for recognizing gestures or strokes entered onto a portion of the display as characters.
- Other displays may be used to display a virtual keyboard.
- the immediate character recognition regions and virtual keyboards require the displays to be of a minimum size to support those kinds of character entry.
- the size of the handheld computer typically must also accommodate mechanical actuators, such as buttons or pivot switches. These are typically placed on the same surface where the display is viewable to enable users to coordinate button actions with what is shown on the display.
- handheld computing devices that also function as wireless telephones.
- Conventional fixed placements of speaker and microphone in these integrated devices yield larger form factors that result in undesirable telephony experiences and do not provide for protection of the integrated display.
- Embodiments of the invention provide for a handheld computer comprising a first segment moveably coupled to a second segment.
- the second segment can be positioned to overlay a portion of the first segment so as to reduce a length of the handheld computer.
- the handheld computer can be manipulated into a contracted position so that the second segment is overlaid over a portion of the display on the first segment.
- a position sensor detects the relative position of the first and second segments to provide feedback to the display.
- the display includes floating text, images, or icons or that may repositioned in response to changes in position of the second segment so that they remain visible. Icons that are associated with keys located at the edge of the second segment may be kept in proximity to the keys so as to enhance the association between the icons and the keys.
- the edge of the second segment that borders the display is used to underline a character string on the display.
- the character string may be one of a plurality of character strings displayed as a static list.
- a key or other actuator may be used to cause an instruction set associated with the character string to be executed.
- a character string that has an associated instruction set is generally a macro command with the instructions and character strings being freely selected.
- a special type of macro command is an address command.
- Character strings such as names of an entity and/or their addresses (e.g., email addresses, IP addresses, or telephone numbers) may be displayed as an address command.
- Line selection of an address command initiates a communications application using the associated address (e.g., an email or telephone call.)
- a handheld computer provides integrated telephone functionality.
- the integrated device has two distinct elements that reconfigure relative to each other through a sliding mechanism.
- the lower element houses the numerical dialer keys and microphone for telephone functionality in addition to the navigation/application keys.
- the upper element houses the display/PCB/battery/speaker, etc.
- the lower housing slides over a majority of the display module in the closed position.

- Embodiments of the invention describe a handheld computer having moveable segments to affect a size of the handheld computer.
- numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.
- a handheld computer includes multiple segments that are moveably connected and adjustable to affect an overall size of the handheld computer.
- a first segment is moveably connected to a second segment.
- the first segment includes a contact-sensitive display.
- the second segment includes an input mechanism.
- the first segment and second segment can be moved between a contracted position and an extended position. In the contracted position, the second segment is overlaid relative to the first segment so that a portion of the display assembly is not accessible. In the extended position, the second segment is moved away from the display assembly so that all of the display assembly is accessible to a user of the handheld computer.
- a second segment is slideably coupled to the first segment.
- the second segment can be positioned relative to the first segment to overlay and reduce an area of the contact-sensitive display assembly.
- Moveable refers to movement in one or more directions, including rotations, and combinations of motions. Slideable means movement primarily in one direction.
- a display surface is accessible if the surface can be contacted by the user.
- the display surface does not have to be contact-sensitive to be accessible.
- the term accessible refers only to a physical relationship between the display and other surfaces of the handheld computer. If the display surface is accessible, then that display surface is not being shielded by another component or surface of the handheld computer.
- embodiments of the invention allow for a handheld computer to vary the overall length of the handheld computer by adjusting the position of the segments relative to one another.
- a user can maintain the handheld computer in a shortened or contracted state if the user does not need to use certain features that can be covered by the segments in the contracted position. For example, portions of the display dedicated to or used primarily for character entry may be covered by the contracted segments of the handheld computer if the user does not need to use the character entry feature of the handheld computer. This allows the user to extend the handheld computer for limited instances when character entry is desired. Therefore, minimization of the size of the handheld computer is not as constrained by character entry features or input mechanisms.
- buttons or other mechanical input mechanisms can be more centrally disposed on the handheld computer. This allows the user to operate the device with one hand, with a thumb or extending to manipulate the buttons. In this configuration, the weight of the handheld computer is more evenly distributed to lessen the strain on the user's hands and thumbs.

Abstract
Description
- This patent application is a continuation-in-part of, and claims priority to, U.S. patent application Ser. No. 09/932,213, “Handheld Computer Having Moveable Segments That Can Be Adjusted to Affect a Size of the Handheld Computer”, filed Aug. 17, 2001.
- The present invention relates to handheld computers. In particular, the present invention relates to a handheld computer comprised of a moveable assembly that is adjustable to affect a size of the handheld computer.
- Handheld computers, typically referred to as personal digital assistants (PDAS), are intended to be mobile devices. In general, small sizes are desired for handheld computers to enhance mobility. However, there are constraints to how small a handheld computer can be for convenience of the user. In particular, certain characteristics of handheld computers require a minimum amount of space on the exterior housing of the handheld computer.
- Most handheld computers require a minimum size display. The minimum display size is set by balancing considerations such as mobility with the need for the user to view data, such as personal management information, pictures, and text pages. For some handheld computers, the size of the display may also need to be large enough to provide a character input mechanism for the user. For example, some handheld computers incorporate character recognition logic as a primary means for the user to enter character data into the handheld computer. The displays for the handheld computer may be made to be contact-sensitive. A portion of the display may be combined with logic to provide an immediate character recognizer for recognizing gestures or strokes entered onto a portion of the display as characters. Other displays may be used to display a virtual keyboard. The immediate character recognition regions and virtual keyboards require the displays to be of a minimum size to support those kinds of character entry.
- The size of the handheld computer typically must also accommodate mechanical actuators, such as buttons or pivot switches. These are typically placed on the same surface where the display is viewable to enable users to coordinate button actions with what is shown on the display.
- As battery and printed circuit board technology becomes more advanced, the display size and mechanical actuators are increasingly becoming the primary factors that determine the size of the handheld computer. Reducing the length of the handheld computer requires sacrificing features of the display and/or buttons.
- The functional integration of handheld devices has led to handheld computing devices that also function as wireless telephones. Conventional fixed placements of speaker and microphone in these integrated devices yield larger form factors that result in undesirable telephony experiences and do not provide for protection of the integrated display.
- In fixed form factor devices the display is left exposed and unprotected from debris and facial oils during phone usage. Products that do provide protection with covers and such have the disadvantage of not allowing the user access to the hard phone and/or application buttons if they reside on the cover. This is due to the cover having to be folded or flipped away to provide access to the display during PDA use.
- Embodiments of the invention provide for a handheld computer comprising a first segment moveably coupled to a second segment. The second segment can be positioned to overlay a portion of the first segment so as to reduce a length of the handheld computer. The handheld computer can be manipulated into a contracted position so that the second segment is overlaid over a portion of the display on the first segment. A position sensor detects the relative position of the first and second segments to provide feedback to the display.
- In an embodiment, the display includes floating text, images, or icons or that may repositioned in response to changes in position of the second segment so that they remain visible. Icons that are associated with keys located at the edge of the second segment may be kept in proximity to the keys so as to enhance the association between the icons and the keys.
- In another embodiment, the edge of the second segment that borders the display is used to underline a character string on the display. The character string may be one of a plurality of character strings displayed as a static list. Upon selecting or underlining a character string, a key or other actuator may be used to cause an instruction set associated with the character string to be executed. A character string that has an associated instruction set is generally a macro command with the instructions and character strings being freely selected.
- A special type of macro command is an address command. Character strings such as names of an entity and/or their addresses (e.g., email addresses, IP addresses, or telephone numbers) may be displayed as an address command. Line selection of an address command initiates a communications application using the associated address (e.g., an email or telephone call.)
- In yet another embodiment of the invention, a handheld computer provides integrated telephone functionality. The integrated device has two distinct elements that reconfigure relative to each other through a sliding mechanism. The lower element houses the numerical dialer keys and microphone for telephone functionality in addition to the navigation/application keys. The upper element houses the display/PCB/battery/speaker, etc.
- The lower housing slides over a majority of the display module in the closed position. Advantages to this articulation are:
- decreased overall length of the product for compact storage and/or one handed telephony usage.
- protection of the display from debris and sharp objects during storage.
- protection of the display from facial oils and chemicals during telephony modes when device is placed against face and ear.
- provides a more ergonomically located 5 way center navigation and numerical buttons for data retrieval and telephone dialing.
- partially exposed display is convenient for minimal PDA and/or telephony information display. Recess provides a degree of display protection.
- Embodiments of the invention are illustrated by way of example, and not by way of limitation, in the figures of the accompanying drawings. Like reference numerals are intended to refer to similar elements among different figures.

In the following description, for the purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the present invention. It will be apparent, however, that the present invention may be practiced without these specific details. In other instances, well-known structures and devices are shown in block diagram form in order to avoid unnecessarily obscuring the present invention.
- In an embodiment, a handheld computer includes multiple segments that are moveably connected and adjustable to affect an overall size of the handheld computer.
- In one embodiment, a first segment is moveably connected to a second segment. The first segment includes a contact-sensitive display. The second segment includes an input mechanism. The first segment and second segment can be moved between a contracted position and an extended position. In the contracted position, the second segment is overlaid relative to the first segment so that a portion of the display assembly is not accessible. In the extended position, the second segment is moved away from the display assembly so that all of the display assembly is accessible to a user of the handheld computer.
- In another embodiment, a second segment is slideably coupled to the first segment. The second segment can be positioned relative to the first segment to overlay and reduce an area of the contact-sensitive display assembly.
- Moveable refers to movement in one or more directions, including rotations, and combinations of motions. Slideable means movement primarily in one direction.
- A display surface is accessible if the surface can be contacted by the user. The display surface does not have to be contact-sensitive to be accessible. The term accessible refers only to a physical relationship between the display and other surfaces of the handheld computer. If the display surface is accessible, then that display surface is not being shielded by another component or surface of the handheld computer.
- Among other advantages, embodiments of the invention allow for a handheld computer to vary the overall length of the handheld computer by adjusting the position of the segments relative to one another. A user can maintain the handheld computer in a shortened or contracted state if the user does not need to use certain features that can be covered by the segments in the contracted position. For example, portions of the display dedicated to or used primarily for character entry may be covered by the contracted segments of the handheld computer if the user does not need to use the character entry feature of the handheld computer. This allows the user to extend the handheld computer for limited instances when character entry is desired. Therefore, minimization of the size of the handheld computer is not as constrained by character entry features or input mechanisms.
- Another advantage is that buttons or other mechanical input mechanisms can be more centrally disposed on the handheld computer. This allows the user to operate the device with one hand, with a thumb or extending to manipulate the buttons. In this configuration, the weight of the handheld computer is more evenly distributed to lessen the strain on the user's hands and thumbs.

FIG. 11 ,back panel 162 is moved the distance X along thebottom surface 114. The direction is unilateral, so thatback panel 162 is sliding alongback surface 114. Thesecond segment 120 is moved over the reducedsections 118 offirst segment 110. -
FIG. 12 is a side cross-sectional view ofhandheld computer 100, showingfirst segment 110 andsecond segment 120 configured with respect to displayassembly 125.FIG. 11 is a partial view, showing only a thickness ofhandheld computer 100 corresponding to wheredisplay assembly 125 is housed. - In one embodiment,
display assembly 125 comprises adigitizer 172 combined with ascreen 174. This construction provides for a contact-sensitive display assembly 125. Input may be entered ontodisplay assembly 125 through contact withdigitizer 172. - In an embodiment, immediate
character recognition region 128 may be formed by extendingdigitizer 172 beyondscreen 174 in the lengthwise direction. The result is that input can be received in immediatecharacter recognition region 128, but output cannot be displayed. - Other embodiments that use immediate
character recognition region 128 may combinedigitizer 172 andscreen 174. The immediatecharacter recognition region 128 may be a selectable feature that appears in a designated regions of the viewable display. In most conventions, immediatecharacter recognition region 128 appears towards the bottom of the viewable display. This position also corresponds towards a bottom offirst segment 110. - The immediate
character recognition region 128 ofdisplay assembly 125 may correspond to the location of reducedsection 118 offirst segment 110. Therefore, whensecond segment 120 is moved into the contracted position,second segment 120 is positioned over immediatecharacter recognition region 128. The contracted position ofhandheld computer 100 may correspond to a selected mode where character entry is not possible. However, since input mechanisms 132 (FIG. 1 ) and multi-directional member 134 (FIG. 1 ) are accessible, data may be selected and displayed whenhandheld computer 100 is in the contracted position. - D.

FIG. 17 is a block diagram for a handheld computer 200 formed from moveably coupled segments, under an embodiment of the invention. One of thesegments handheld computer 100 carries a majority of the components for performing the core functions of the handheld computer. In an embodiment,first segment 110 carrying thedisplay assembly 125 forhandheld computer 100 is assumed to have the majority of components. - In an embodiment, handheld computer includes a
processor 240 coupled to a first memory 244 (non-volatile) and a second memory 246 (volatile). Theprocessor 240 is coupled to a display driver 222. Theprocessor 240 combines with display driver 222 to process and signal data for presentation on adisplay assembly 220. The display assembly 520 includes screen and digitizer. - An analog-digital (AD)
converter 232 is coupled toprocessor 240. One or more channels from A/D converter 232 maybe used to convert analog input provided by the digitizer, or by another analog input mechanism. - The
handheld computer 100 may include one or more expansion ports for coupling to accessory devices, such as cradles, modems, memory units, re-chargers and other devices. Examples of expansion ports include serial ports, Universal serial Bus (USB) ports, CompactFlash slots and infra-red ports. In an embodiment shown, afirst expansion port 202 enables one or more types of expansion modules to be connected toprocessor 240. Thehandheld computer 100 may also include a second expansion port 204 to couple to another accessory device. Eachport 202, 204 is shown to be coupled toprocessor 240, although the components that receive a signal from one of theexpansion ports 202, 204 are determined by the type of accessory device selected. - The accessory device that may be coupled to
expansion port 202 may be identified by primary functions of their internal components. Each accessory device may include one or more of the following set of components: a radio-frequency transmitter and/orreceiver 252, aprocessor 254, aninput mechanism 256,additional memory 258, abattery 260, or another A/D converter 262. The same components may be used with expansion modules to second expansion port 204. - Embodiments described herein have provided for
first segment 110 to include a display assembly, andsecond segment 120 to include input mechanisms. The relationship between thesecond segment 120 andfirst segment 110 has included configurations wheresecond segment 120 has been positioned to overlayfirst segment 110. Other embodiments, however, may provide for the relationship betweenfirst segment 110 andsecond segment 120 to be reversed. For example,first segment 110 may be moved so that a display surface over lays the buttons. Thesecond segment 120 may provide for the display assembly whilefirst segment 110 provides for input mechanisms. Other examples and configurations are also contemplated by embodiments of the invention. - While embodiments described above provide for housing segments to reduce a length of
handheld computer 100, other embodiments may provide for a similar configuration to be used for a width ofhandheld computer 100, wherelateral sides first segment 110 andsecond segment 120. - Embodiments described above provide certain configurations for rails and connecting members. While embodiments described provide for

FIG. 18 shows ahandheld computer 1800 similar to that shown inFIG. 1 . Theprocessor module 1801 is similar tofirst segment 110 ofFIG. 1 , andkeypad slider 1802 is similar to thesecond segment 120 ofFIG. 1 . Thekeypad slider 1802 is an example of a sliding display cover having akey pad 1803 for user input. The processor module includes adisplay 1804. Thedisplay 1804 is a preferably a touch panel display; however, it may be a conventional display such as a liquid crystal display (LCD) or it may be a touch panel display capable of accepting input from user. - The
processor module 1801 andkeypad slider 1802 include a sensing device to produce a signal containing information regarding the relative position of theprocessor module 1801 and thekeypad slider 1802. The sensing device may be a contact sensor such as a variable resistance potentiometer, or it may be a non-contact sensing device using an optical or magnetic transducer to detect the relative position. - The signal coupling between the
keypad slider 1802 and theprocessor module 1801 may be achieved by sliding contacts, a flexible ribbon connector. Alternatively, thekeypad slider 1802 and theprocessor module 1801 may be optically coupled (e.g., a light emitting diode and detector pair). - For handheld computers having a touch panel display, the sensing device may be provided by the
touch panel display 1804 and a physical feature incorporated in thekeypad slider 1802. The physical feature may simply be the edge of the keypad slider, or it may be one or more protrusions or sensing features on or near the edge of thekeypad slider 1802 that is adjacent to thedisplay 1804. When thedisplay 1804 is a near field imaging (NFI) or capacitive display, sensing can be done with very light contact and essentially zero displacement at the display surface. For protrusions that establish contact with the display surface, the preferable location is at the edges of the display. For touch panel displays that require a degree of displacement at the input surface, a roller may be used to provide a contact with minimal wear and friction. - When the
touch panel display 1804 is used as the sensing device, the information concerning the geometric relationship between the sensing features, the edge of thekeypad slider 1802 and the touch panel display coordinates is available to the processor. Likewise, the signal from any other type of sensing device would be, correlated with the relative position of thekeypad slider 1802 with respect to theprocessor module 1801. - In an embodiment of the invention, the processor of the
handheld device 1800 uses the available position information to arrange displayed visual objects so that they are viewable in response to the relative position of theprocessor module 1801 with respect to thekeypad slider 1802. Avisual object 1805 is shown on the lower portion of thedisplay 1804 ofFIG. 18 . Thehandheld computer 1800 is in a fully extended configuration and the edge of thekeypad slider 1802 is aligned with the edge of thevisual object 1805. - In
FIG. 19 , the handheld device ofFIG. 18 is shown in a partially closed position. The location of thevisual object 1805 has been changed in order to maintain visibility. Thevisual object 1805 may be made up of one or more icons associated with thetouch panel display 1804, that serve to label areas of the touch screen that are associated with actions performed by theprocessor module 1801. - Alternatively, the
visual object 1805 may be a collection of icons associated with keys on theadjacent keypad slider 1802. The sensing device signal may be used to maintain proximity between icons displayed on thedisplay 1804 and the edge of thekeypad slider 1802. - In response to the shrinking of the visible area of the
display 1804, the processor may scale the size of the overall display image, or maintain the size of the image and scroll it, or both. - In another embodiment of the invention, the information from the sensing device is used to reference a collection of symbols presented on a display of a handheld computer.
FIG. 20 shows ahandheld computer 2000 having aprocessor module 2001, akeypad slider 2002, aselect button 2003, and adisplay 2004. - The
display 2004 shows amacro command list 2005. A macro command is a string of one or symbols arranged in a line approximately parallel to the edge of thekeypad slider 2002. For example, a macro command may be an ASCII character string that refers to an executable command or series of commands. For example, the character string may be an email address or telephone number that may be selected for sending an email or initiating a telephone call. Once selected, the macro command may be executed by appropriate input such as pressing theselect button 2003. -
FIG. 21 shows the handheld computer ofFIG. 20 with the macro command “macro command 1” 2100 selected. A desired macro command is selected by adjusting the position of thekeypad slider 2002 with respect to theprocessor module 2001 so that the edge, of thekeypad slider 2002 underlines the desired macro command. Once selected, a macro command may be executed by pressing the select button'2003. The set of instructions used by the processor to select a macro command is referred to as a line selection driver: - The assignment of an instruction or series of instructions to a character string has a particular advantage over assignment to a key or combination of keys. A character string may serve as an effective mnemonic device. For example, associating a telephone number or email address with a person's name as a macro command is more natural than associating the person's telephone number or email address with a number.
-
