Description
Technical field
The present invention relates to the control method of input equipment, messaging device, remote control equipment and input equipment, specifically, relate to whether just on the front surface of panel, carrying out pressing operation or touch operation detects and the input equipment of the data that input is corresponding with pressing operation or touch operation, use this input equipment messaging device, use the control method of remote control equipment and this input equipment of this input equipment.
Background technology
Use the input equipment of touch panel to be widely used in: the ATM (Automatic Teller Machine) in the bank; The automatic machine (automatedtichet vender) of train ticket or commuter's ticket (commuting passes) etc.; That in convenience store, use, that be used for ticketing and other service, so-called convenience store terminal; And such as messaging device of PDA (personal digital assistant) etc.By make be presented at such as the button on the display device of LCD (LCD) relevant with icon with coordinate system, and detect finger or such as indicating device (pointing device) position contacting on panel of pen, the touch panel type input equipment has been realized for the user's of these equipment GUI (Graphic Operator Interface, graphical operator interface therewith).
Utilize many such touch panel type input equipments different with the common input equipment that uses true shift knob, the operator can not actually feel click feel (click sense).Therefore, touch panel type input equipment recently sends the operation sound such as beep sound, and/or the shape of change the Show Button corresponding with operator's input operation, so that he or she has carried out input operation by the sense of hearing or visual notification.
But when the operator used this input equipment, this input equipment may be very slow to the response of input operation, perhaps, and not operation.If the operator has made a mistake input operation, then he or she can be worried to the operability of input equipment.Therefore, not talkative traditional touch panel type input equipment is convenient to operation.
In order to address this problem, proposed for example piezo-electric device to be arranged in the mechanism directly over the panel.In this mechanism, when the operator carried out input operation, piezo-electric device made panel carry out the distortion corresponding with input operation, with the sensation to his or she feedback force.Like this, when operator's operation input apparatus, he or she can feel click feel as pressing shift knob.
In legacy equipment, use resistive film (resistive film) type touch panel.In the resistive film type touch panel, with the stacked a plurality of flexible electrical pole pieces of predetermined space, make they electrode surface toward each other.In this equipment, bobbin coil (bobbin coil) is mounted on the shell of fixing touch panel.For example, in [0040], Fig. 3, Fig. 6 and Fig. 7 this equipment is disclosed at the paragraph [0037] of not examining Japanese Patent Application No.2002-259059.In this input equipment, when the operator presses touch panel, electrode slice is in contact with one another and produces electric current.As a result, bobbin coil is operated and with the anti-operator of pushing to of touch panel.Therefore, the operator can feel click feel.
In the input equipment that another kind proposes, support touch panel by piezo-electric device.That utilization occurs in piezo-electric device, corresponding with press pressure on touch panel voltage detects operating physical force.(for example, in [0143], Figure 15 and Figure 16, disclosing this equipment) at the paragraph [0132] of not examining Japanese Patent Application No.HEI 11-212725.Therefore, when the operator presses touch panel, do not push stroke (press stroke).But the operator can feel click feel.
But in traditional touch panel type input equipment, when operator's guidance panel, he or she can not feel the stroke sense.In addition and since the touch panel type input equipment after his or she guidance panel with the fine delay send click sound, with the anti-operator of pushing to of panel, perhaps make panel vibration, so these input equipments can not be eliminated the worry of operator to touch panel.Therefore, the touch panel type input equipment can't satisfy the requirement of virtual switch.
Because the operator knows the sense of touch of true switch, therefore when he or she pushes the panel of this touch panel type input equipment, he or she can't feel this stroke sense.If in operator presses after the panel, he or she has felt very strong sensation on touch panel, then he or she may feel ill.
In other words, the touch panel type input equipment not only needs to provide feedback to the operator, and need make the operator that virtual stroke sense is arranged, and seems that he or she has pushed shift knob.
No matter the dynamics of operator presses panel is how, traditional touch panel type input equipment all makes panel deformation, and to the sensation of operator's feedback force.In input equipment, panel is pushed with the variety of way that depends on the operator.Specifically, the operator who is unaccustomed to this equipment often pushes panel with strength.This is because the mode that the unattended operation person pushes panel how, is identical from the feedback of panel.The operator does not know to push with him or she the pressure corresponding equipment response of panel.As a result, the operator will be not good to the impression of the operability of touch panel.
When the operator presses panel, if he or she obtains feedback, he or she can think that operation is reliable.But if the operator pushes panel with strength, his or her finger can be tired.When the operator got used to input operation, he or she can push panel like a cork.But if constant from the feedback of panel, then the operator is difficult to learn to push in the best way panel.Specifically, if the operator is unaccustomed to the operation of counter plate, he or she is often mistaken to operate.
According to above-mentioned viewpoint the present invention has been proposed.The purpose of this invention is to provide and a kind ofly when operator's counter plate is operated, make him or she can feel the input equipment and the control method thereof of stroke virtually.
In addition, the purpose of this invention is to provide a kind of messaging device and remote control equipment that uses this input equipment.
In addition, the purpose of this invention is to provide a kind of input equipment and control method thereof, it makes the mode that panel can operate corresponding to operator's counter plate and is out of shape, so that to the sensation of operator's feedback force.
In addition, the present invention will provide a kind of messaging device and remote control equipment that uses this input equipment.

Fig. 1 is the summary exploded perspective view that shows according to the input equipment of present embodiment of the present invention.
Input equipment 100 shown in Figure 1 has liquid-crystal display section 1 and is positioned at touch panel part 2 on the display surface of liquid-crystal display section 1.Flexible board 4 is fixed in the display surface side of liquid-crystal display section 1.Piezo-activator 3 is installed on each flexible board 4.
Liquid-crystal display section 1 has the display panel 1a of display image and the framework 1b of clamping display panel 1a thereon.Display panel 1a comprises crystal liquid substrate and (not shown) such as backlight.Framework 1b is made by for example metal.Arrange framework 1b to such an extent that make its unlikely viewing area that stops the display surface of display panel 1a.
Touch panel part 2 has the sensor that the input operation to the operator detects.In this example, touch panel part 2 is the resistive film type touch panels with resistive film type sensor.Touch panel part 2 comprises the pressing part 2a of operator presses and the framework 2b that pressing part 2a is carried out clamping.Pressing part 2a is made by the transparent resin sheet.Pressing part 2a sees through the image that shows on the display panel 1a of liquid-crystal display section 1.Framework 2b is made by for example metal.Arrange framework 2b to such an extent that make its unlikely viewing area that stops display panel 1a.
Resistive film type touch panel as touch panel part 2 comprises positioned opposite and a plurality of electrode slice spaced apart by a predetermined distance.When the operator pushed pressing part 2a shown in Figure 1 with his or her finger or such as the indicating device of pen, electrode slice was in contact with one another.At this moment, by the resistance variations on each electrode slice is detected, be coordinate figure with the location recognition of indication.
Piezo-activator 3 is piezoelectric bimorph devices (piezoelectric bimorphdevice) for example.The piezoelectric bimorph device has the structure that battery lead plate is clipped in the middle by a plurality of piezoelectric patches.When two surfaces to the piezoelectric bimorph device applied voltage, bimorph device was often crooked.In input equipment 100, the bending of piezo-activator 3 and distortion are corresponding with the driving voltage that applies by the wiring that forms on flexible board 4.
In input equipment 100, the display surface of liquid-crystal display section 1 and touch panel part 2 are clipped in the middle flexible board 4 and piezo-activator 3.The pressing part 2a of touch panel part 2 make show by the display panel 1a of liquid-crystal display section 1, see through such as the image of the operating function item of icon.When the operator during pressing image display position, carries out the input operation corresponding with display image on pressing part 2a.
Liquid-crystal display section 1 and touch panel part 2 are installed on the shell (not shown) of input equipment 100.Here, touch panel part 2 is disposed on the liquid-crystal display section 1, thereby touch panel part 2 can move perpendicular to display surface.Therefore, crooked and when being out of shape when piezo-activator 3, liquid-crystal display section 1 and the distance change of touching between the face plate portion 2.For example in shell, arrange the circuit that the pressing operation at touch panel part 2 is detected and piezo-activator 3 is carried out the drive controlling corresponding with pressing operation.
Fig. 2 shows the state that piezo-activator is installed on flexible board.Fig. 2 A is the summary planimetric map that shows flexible board, and Fig. 2 B is the sectional view along line X-X intercepting.
As shown in Figure 2, flexible board 4 has mounting portion 41, and mounting portion 41 comprises a pair of through hole 41a and 41b and wiring pattern 42a and 42b, wherein, utilize through hole 41a and 41b that piezo-activator 3 is installed, utilize wiring pattern 42a and 42b to provide driving voltage piezo-activator 3.
In mounting portion 41, form close and identical through hole 41a and the 41b of shape.Between through hole 41a and 41b, form central interval body part 41c.The interval body part 41c of central authorities is the bridge shape resin molding that constitutes flexible board 4.According to present embodiment, on each flexible board 4, arrange two mounting portions 41.
Form wiring pattern 42a and 42b, make these wirings be connected to an end of mounting portion 41.On an end of piezo-activator 3, form cloth line terminals 31a and 31b.When cloth line terminals 31a and 31b contact wiring pattern 42a on the flexible board 4 and 42b respectively, driving voltage is offered piezo-activator 3 from the drive circuit (not shown).
Piezo-activator 3 is inserted the through hole 41a from the front of mounting portion 41.Then, via central interval body part 41c piezo-activator 3 is inserted the through hole 41b from the back of mounting portion 41.Thus, piezo-activator 3 is installed on the flexible board 4, so that the front surface of the two end in contact flexible boards 4 longitudinally of piezo-activator 3.The rigidity of piezo-activator 3 is higher relatively, and flexible board 4 easy deformation.Therefore, shown in Fig. 2 B, under the state that has only central interval body part 41c upwards to be out of shape, by mounting portion 41 clamping piezo-activators 3.At this moment, the cloth line terminals 31a that forms at an end of piezo-activator 3 contacts wiring pattern 42a and the 42b that forms respectively with 31b on flexible board 4.Therefore, cloth line terminals 31a and 31b are electrically connected to wiring pattern 42a and 42b respectively.Preferably, cloth line terminals 31a and 31b respectively with wiring pattern 42a with after 42b contacts, for example utilize the scolder butt contact to fix, so that piezo-activator 3 itself is fixed on the flexible board 4.
After piezo-activator 3 has been installed in the manner described above, utilize the framework 1b of liquid-crystal display section 1 and the framework 2b of touch panel part 2 that flexible board 4 is clipped in the middle.Like this, for example, the upper surface (shown in Figure 2) of central interval body part 41c contacts with the framework 2b of touch panel part 2.For example, the lower surface (shown in Figure 2) of central interval body part 41c and piezo-activator 3 contacted regional 43a contact the framework 1b of liquid-crystal display section 1 with 43b.In this mounting structure, the central interval body part 41c of flexible board 4 is as the framework 2b of touch panel part 2 and the interval body between the piezo-activator 3.On the other hand, the regional 43a of flexible board 4 and 43b are as the framework 1b of liquid-crystal display section 1 and the interval body between the piezo-activator 3.
In this state, when providing driving voltage to piezo-activator 3, this piezo-activator 3 is for driving voltage and crooked and distortion.As mentioned above, piezo-activator 3 has two cloth line terminals 31a and 31b.When the voltage between these cloth line terminals 31a and the 31b was 0, piezo-activator 3 was not crooked.Along with voltage increases, piezo-activator 3 is crooked significantly.When the reversal of poles of voltage, the counter-rotating of the direction of piezo-activator 3 bendings.Therefore, when in input equipment 100, the voltage (amplitude) of driving voltage, frequency, waveform (square wave or sine wave) etc. being controlled, can aspect curvature, flexure cycles and bending direction, change size, cycle and the direction etc. of piezo-activator 3 bendings.
When piezo-activator 3 bendings, because its middle body distortion, therefore central interval body part 41c is towards liquid-crystal display section 1 vertical moving.Therefore, when central interval body part 41c was out of shape, touch panel part 2 moved and the front surface of panel is out of shape.As a result, touch panel part 2 feels to feed back to the operator with power.
Can front surface or the two ends of central interval body part 41c and the back side in piezo-activator 3 contacted zones of central interval body part 41c will be adhered to by the reinforced sheet of making such as the higher material of the rigidity of celluloid.
The installation method of aforesaid piezo-activator 3 is an example.As long as an interval body is arranged as middle body near a surface of piezo-activator 3, and a plurality of interval bodies are arranged in two ends longitudinally along another surface, just can according to preceding method diverse ways installation piezo-activator 3.
Hardware configuration according to the input equipment 100 of first embodiment of the invention will be described below.According to first embodiment, input equipment 100 is represented by input equipment 100a.
Fig. 3 shows the hardware block diagram according to the input equipment of first embodiment.
Input equipment 100a according to first embodiment has Sensor section 101, position judgment processing unit 102, control section 103 and drive part 104.
Sensor section 101 is arranged in touch panel part 2.Sensor section 101 has whether the operator is just being carried out the sensor that touch operation detects on input equipment 100a.According to the resistive film system, whether the front surface of the panel of 101 pairs of touch panel parts 2 of Sensor section (touching part 2a) is being pressed and is detecting.
When the operator pushes front surface as the panel of the artifical resistance membranous type touch panel of the touch panel part 2 in the present embodiment with his or her finger etc., by positioned opposite and electrode slice spaced apart by a predetermined distance contact and conduction.The resistance change at the contact position place on electrode slice (as the XY coordinate figure).Therefore, the magnitude of voltage of locating at contact position (as the XY coordinate figure) changes.Wait with finger push the front surface of resistive film type touch panel before, the magnitude of voltage of locating at contact position (as the XY coordinate figure) is 0V or near 0V.Along with the front surface of panel is pushed continuously, resistance value increases gradually.When this front surface had been pressed the schedule time, it is saturated and constant that magnitude of voltage becomes.
When magnitude of voltage becomes when stablizing, input equipment 100a confirms that the operator has pushed panel.Pushed panel, magnitude of voltage the operator and become and be stabilized in the predetermined variation scope and after having passed through predetermined amount of time, input equipment confirms that the operator has pushed panel.Can for input equipment 100a preestablish from voltage become stable after time period till pressing operation is identified.
Sensor section 101 utilizes the magnitude of voltage (simulating signal) that (XY coordinate figure) located in a position, and whether the front surface of counter plate is being pressed is detected.This magnitude of voltage is carried out the A/D conversion and is detected. as data value (digital signal).
Position judgment processing unit 102 regularly reads by Sensor section 101 data values detected, that (XY coordinate figure) located in this position, variation to detected data value is monitored, and the pushing zero-time and push acknowledging time of the front surface of definite panel.In other words, position judgment processing unit 102 time that detected data value is begun to change is defined as pushing zero-time.On the other hand, position judgment processing unit 102 time of detected data value having been become stable and having passed through predetermined amount of time is defined as pushing acknowledging time.
After detected data value had become stable and passed through predetermined amount of time, input equipment 100a confirmed that the front surface of panel is pressed.At this moment, position judgment processing unit 102 utilizes detected data value that the X-Y coordinate figure at the pressing position place on electrode slice is discerned, and the coordinate figure that is identified is stored as positional information.Can replace hardware module to realize the processing of position judgment processing unit 102 with CPU.
In addition, corresponding with input state, the control signal of till pressing operation is identified, being exported after the front surface that position judgment processing unit 102 is created on panel is pressed, and, the control signal of pressing operation is identified after, exporting.102 pairs of control sections of position judgment processing unit 103 carry out the control corresponding with control signal.The control signal that is generated by position judgment processing unit 102 is the digital signal that comprises voltage (amplitude), frequency and waveform (square wave or sine wave).
Control section 103 is waveform generating apparatus.The control corresponding with the control signal that provides from position judgment processing unit 102 is provided for control section 103 pairs of voltages, frequency and waveforms, so that generate the signal waveform of driving voltage, control section 103 utilizes this signal waveform that drive part 104 is driven and this signal waveform is output as output signal.
Fig. 4 is the synoptic diagram that shows according to the topology example of the control section of first embodiment.
As shown in Figure 4, control section 103 for example has D/A conversion portion 103a, Waveform Control part 103b and drive circuit 103c.
The voltage transitions that D/A conversion portion 103a will be included in from the control signal of position judgment processing unit 102 outputs is the analogue value, and will output to drive circuit 103c through the control voltage of conversion.
Waveform Control part 103b utilizes frequency and the waveform that is included in from the control signal of position judgment processing unit 102 outputs, generates square wave or sine wave with preset frequency, and the control waveform that is generated is outputed to drive circuit 103c.
With the control voltage of exporting from D/A conversion portion 103a and corresponding from the control waveform of Waveform Control part 103b output, drive circuit 103c outputs to drive part 104 with the signal waveform of driving voltage.
Because control section 103 produces the output signal that drive part 104 is controlled, therefore, as long as control section 103 can generate the signal waveform corresponding with drive part 104, the structure of control section 103 is not limited to foregoing example so.
Drive part 104 is aforementioned piezo-activators 3.The bending of piezo-activator 3 and distortion are corresponding with the signal waveform of the driving voltage of exporting from control section 103.To offer drive part 104 such as the alternating voltage of ac square-wave voltage or AC sine wave voltage.When providing this AC drive voltage to piezo-activator 3, piezo-activator 3 can slight vibration.Therefore, can make touch panel part 2 slight vibration.
Below, will make the operator feel that the method for virtual stroke is described to utilizing aforesaid input equipment 100a.
Fig. 5 shows the curve map of the relation between the driving voltage that is used to illustrate panel compressing time section and piezo-activator.The upper curve of Fig. 5 illustrates the panel compressing time section of touch panel part 2 and the relation between the detected data value.The lower curve of Fig. 5 illustrates the signal waveform of the driving voltage that offers piezo-activator 3.In addition, the upper curve of Fig. 5 illustrates the variation of detected data value along directions X.
Shown in the upper graph of Fig. 5, before the front surface of the panel of touch panel part 2 was pressed, detected data value was 0 or approaches 0 in input operation.When the front surface of the panel of touch panel part 2 was pushed continuously, detected data value increased gradually.When the front surface of panel was continued to push, detected data value became stable.Corresponding with the variation of the detected data value shown in the upper graph of Fig. 5, the driving voltage that input equipment 100a will have the signal waveform shown in the lower graph of Fig. 5 offers piezo-activator 3.Therefore, input equipment 100a makes the operator can feel virtual stroke.
In other words, till pressing operation was identified, input equipment 100a provided the ac square-wave voltage that amplitude is little, frequency is high to piezo-activator 3 after pressing operation begins, and made piezo-activator 3 slight vibration and made touch panel part 2 weak vibrations.After pressing operation was identified, input equipment 100a provided the ac square-wave voltage that amplitude is big, frequency is low to piezo-activator 3, and piezo-activator 3 and touch panel part 2 are obviously vibrated.Time period after pressing operation begins till pressing operation is identified is that about tens ms are to 100ms.Since after pressing operation begins till pressing operation is identified, touch panel part 2 weak vibrations and with power feel to feed back to the operator, so he or she can feel the stroke sense of having pushed shift knob as him or she.In addition, because after pressing operation is identified, the operator feels judder, and therefore, he or she can feel the click feel of having pushed shift knob as him or she.
When the application for input equipment 100a of input equipment 100a according to operator's use, when making him or she feel the stroke sense of growing, he or she may feel comfortable.
Fig. 6 shows another curve map of the relation of the driving voltage that is used to illustrate panel compressing time section and piezo-activator.The upper curve of Fig. 6 illustrates the relation between panel compressing time and the detected data value.The lower curve of Fig. 6 illustrates the signal waveform of the driving voltage that offers piezo-activator 3.In addition, the upper curve of Fig. 6 illustrates the variation of detected data value along directions X.
Shown in the upper graph of Fig. 6, identical with the upper graph of Fig. 5, before the front surface of the panel of touch panel part 2 was pressed, detected data value was 0 or approaches 0 in input operation.When the front surface of the panel of touch panel part 2 was pushed continuously, detected data value increased gradually.When the front surface of panel was continued to push, detected data value became stable.
In order to make the operator feel that as shown in Figure 6,100a is provided with to input equipment, makes pressing operation be identified lateer than long stroke sense.Till pressing operation was by slower affirmations, input equipment 100a provided the ac square-wave voltage that amplitude is little, frequency is high to piezo-activator 3 after pressing operation begins.After this, input equipment 100a provides the ac square-wave voltage that amplitude is big, frequency is low to piezo-activator 3.Therefore, after pressing operation begins up to pressing operation by slower till confirm, piezo-activator 3 and touch panel part 2 weak vibrations.After this, piezo-activator 3 and 2 judders of touch panel part.Therefore, the operator can feel long stroke sense.
In Fig. 5 and example shown in Figure 6, provide ac square-wave voltage to piezo-activator 3.Certainly, also can provide the AC sine wave voltage to piezo-activator 3.But, comparing with sine wave, the operator is easier to be identified as vibration with square wave.In addition, the voltage of square wave can be lower than the voltage of sine wave.
In input equipment 100a, make the operator feel the stroke sense driving voltage voltage, frequency, waveform and provide the time period depend on utilization from touch panel part 2 detected magnitudes of voltage and definite push acknowledging time, for type of the application of input equipment 100a etc.Therefore, can freely set in advance them.
When after pressing operation begins till pressing operation is identified, when input equipment 100a makes piezo-activator 3 and touch panel part 2 weak vibrations, can change the frequency of piezo-activator 3 and touch panel part 2.For example, when pressing operation begins, input equipment 100a can become 100Hz from 50Hz with the frequency of piezo-activator 3 and touch panel part 2, and can with voltage from input equipment 100a make the operator feel click feel crest voltage 1/2 change to 1/8 so that piezo-activator 3 and touch panel part 2 are with square wave vibration.Therefore, the operator can feel and feels the stroke sense of true stroke as him or she.But, if frequency and overtension, then the operator may hear faint, that can hear, make the operator feel the vibration of stroke sense.According to the mounting condition of input equipment 100a, this too high frequency and voltage make the operator feel noise.Therefore, should think better of this point.
In addition, because the liquid-crystal display section and the touch panel of common input equipment partly be spaced, so the operator may be pressed into the position of the non-the Show Button on the touch panel owing to parallax.In this case, equipment is not accepted input.In this case, when the operator presses panel, input equipment 100a provides predetermined driving voltage to piezo-activator 3 so that piezo-activator 3 weak vibrations, makes the operator feel click feel.After this, input equipment 100a may stop to provide driving voltage to piezo-activator 3, thus piezo-activator 3 stop the vibration, make the imperceptible click feel of operator.Therefore, the operator can identify him or she and push panel.In addition, because the imperceptible click feel of operator, so he or she can identify him or she and is pushing out of position on the panel.
In this case, piezo-activator 3 can be to make the operator feel that the different mode of the mode of vibration of stroke sense and click feel vibrates with it.Perhaps, input equipment 100a can produce alerting tone.
In the description in front, have the touch panel part 2 of the resistive film type touch panel of resistive film type Sensor section 101 as input equipment 100a.Touch panel part 2 can be used various types of touch panels, as capacitor type, optical type, ultrasonic type or electromagnetic induction type etc., so that the operator feels stroke sense and click feel.In other words, as long as sensor in any variation the detected signal (detected data value) till input operation is identified after input operation begins, just can make the operator feel the stroke sense.
When touch panel part 2 was capacitive based touch panel, the operator was formed by the electrically conducting transparent panel with the touch part of his or her finger touch.Make the circuit that applies voltage and detect electric current be positioned at framework the inside (under the outward flange that touches part).The conduction panel is applied constant voltage.As operator during with the touch panel of his or her finger touch input equipment, the electric capacity of panel changes.The electric capacity that changes is detected as current value.
When touch panel part 2 was the touch panel of optical type, touching part was to be made of the transparent panel that glass or acryl resin etc. is made.To be arranged in framework the inside (under the outward flange that touches part) such as light-emitting device and the optical pickup apparatus of LED (LCD).Utilize the infrared ray of matrix shape that the front surface that touches part is carried out radiation.By relative optical pickup apparatus receiving infrared-ray.As operator during with the front surface of the panel of his or her finger touch input equipment, infrared ray is blocked.The ultrared variation that is blocked is detected as electric signal.
When touch panel part 2 is the touch panel of ultrasonic type, touches part and constitute by transparent panel.Transmitter and receiver are arranged in framework the inside (under the outward flange that touches part), make them relative with the Y direction along X.Oscillator produces surface acoustic wave on the front surface that touches part.As operator during with the front surface of the panel of his or her finger touch input equipment, the vibration that touches part is by finger.Thus, detect the delay of surface acoustic wave.
When touch panel part 2 is the touch panel of electromagnetic induction type, utilize to be included in the touch that constitutes by transparent panel and partly to go up the circuit that produces magnetic field and carry out input operation at interior pen type indicating device etc.Go up the many cell windings that magnetic field is detected of layout at the dorsal part (at the dorsal part of operating surface) of panel, as Sensor section.When the operator utilized the front surface of indicating device contact touch panel, Sensor section detected the variation in magnetic field.
During in the middle of using these types one type, the flexible board that piezo-activator has been installed is disposed between the framework as the framework of the panel that touches part and liquid-crystal display section.In any kind, after detected data value changes, become time period till stablizing up to it, that is, and from input operation begin time period till input operation is identified at about tens ms in the scope of 100ms, similar to resistive film type.The signal that changes when the front surface of operator's touch panel is detected.Corresponding with this signal, generation offers the signal waveform of the driving voltage of piezo-activator.Corresponding with this signal waveform, piezo-activator is driven, so that panel vibration.Therefore, the operator can feel stroke sense and click feel.
As mentioned above, in touch panel type input equipment according to first embodiment of the invention, the operator after the input operation of the front surface of operator presses or touch panel, till input operation is identified, makes the panel weak vibration, so that can feel the stroke sense.Therefore, the operator can carry out input operation reliably.Therefore, the operator can know when he or she begins to push for input operation panel.Therefore, the operator can enough his or her fingers etc. continues remaining input operation.In addition, utilize the weak vibration that feeds back on the panel, the operator can know unconsciously that his or her operation is correct.Therefore, the operator can push panel lightly with his or her finger etc.
When the non-the Show Button zone on the panel of operator presses tradition input equipment, traditional input equipment is to not reaction of such operation.Therefore, the operator can not determine he or she be with the Show Button by light, still pushed the Show Button improperly.But in input equipment according to the present invention, when the operator presses panel, because panel vibration, so he or she feels the stroke sense.Therefore, at least, the operator can identify him or she and push panel.When the non-the Show Button on the operator presses panel, because input equipment stops to make panel vibration, so the operator can not feel click feel.Therefore, the operator can identify him or she and push out of position on the panel.Perhaps, input equipment can make panel vibration with the error notification operator or may produce alarm.Therefore, can alleviate the operator, to the stress of the maloperation of input equipment.
Because the operator is depended on the operability of input equipment to the impression of total system, therefore, the touch panel type input equipment is important interface portion.Input equipment according to the present invention makes the operator who is unaccustomed to input operation feel reliable and self-confident.
Hardware configuration according to the aforementioned input equipment 100 of second embodiment of the invention will be described below.Input equipment 100 according to second embodiment is represented by input equipment 100b.
Fig. 7 is the block diagram that shows according to the hardware of the input equipment of second embodiment.
When the operator pushes front surface as the panel of the artifical resistance membranous type touch panel of the touch panel part 2 in the present embodiment with his or her finger etc., contacted by positioned opposite and electrode slice spaced apart by a predetermined distance and conduct electricity.The resistance change that contact position on electrode slice (as the XY coordinate figure) is located.Therefore, the magnitude of voltage of locating at contact position (as the XY coordinate figure) changes.Wait with finger push the front surface of resistive film type touch panel before, the magnitude of voltage of locating at contact position (as the XY coordinate figure) is 0V or near 0V.Along with the front surface of panel is pushed continuously, resistance value increases gradually.When this front surface had been pressed the schedule time, it is saturated and constant that magnitude of voltage becomes.
When magnitude of voltage becomes when stablizing, input equipment 100b has confirmed operator presses panel.Pushed panel, magnitude of voltage at him or she and become and be stabilized in the predetermined variation scope and after having passed through the schedule time, input equipment confirms that the operator has pushed panel.Can for input equipment 100b preestablish from voltage become stable after time period till pressing operation is identified.
Position judgment processing unit 112 regularly reads by Sensor section 111 detected data values (XY coordinate figure), variation is monitored, and determine to push zero-time and push acknowledging time.In other words, the time that position judgment processing unit 112 is changing detected data value has been defined as pressing off time beginning, and the time that detected data value has been become stable and passed through predetermined amount of time is defined as pushing acknowledging time.Like this, the position judgment processing unit 112 utilization timer that for example is arranged in input equipment 100b is to measuring to the time period of pushing till the acknowledging time from pushing zero-time.
In addition, position judgment processing unit 112 is utilized detected data value, X-Y coordinate figure to the pressing position place on electrode slice is discerned, and, detected data value become stable, passed through predetermined amount of time and confirmed pressing operation after, the coordinate figure that is identified is stored as positional information.
Position judgment processing unit 112 generate with from pushing zero-time to corresponding control signal of the time period of pushing acknowledging time, and, corresponding to this control signal, control section 113 is controlled.Perhaps, position judgment processing unit 112 can compare time period and the predetermined amount of time that measures, and whether the time period of determining to measure is than preset time segment length, and the generation control signal corresponding with definite result.
The control signal that is generated by position judgment processing unit 112 is the digital signal that comprises voltage (amplitude) condition, and position judgment processing unit 112 utilizes this digital signal to discern the signal waveform of the driving voltage that drive part 114 is driven.In this case, will have amplitude corresponding to offering drive part 114 from the driving voltage of pushing the signal waveform that zero-time changes to the Measuring Time section of pushing acknowledging time.When the driving voltage with signal waveform that frequency or waveform (square wave or sine wave) rather than amplitude change corresponding to the time period that measures was provided for drive part 114, these conditions may be included in the control signal.
Fig. 8 is the synoptic diagram that shows according to the topology example of the control section of second embodiment.As shown in Figure 8, control section 113 for example has D/A conversion portion 113a and drive circuit 113b.The voltage transitions that D/A conversion portion 113a will be included in from the control signal of position judgment processing unit 112 outputs is the analogue value, and will output to drive circuit 113b through the control voltage of conversion.Corresponding with the control voltage from D/A conversion portion 113a output, drive circuit 113b as output signal, outputs to drive part 114 with the signal waveform of driving voltage.
Because control section 113 generates the output signal of control sections 113 in order to drive part 114 is controlled, therefore, as long as control section 113 can generate the signal waveform corresponding with drive part 114, then the structure of control section 113 is not limited to such example.
Drive part 114 is aforementioned piezo-activators 3.The bending of piezo-activator 3 and distortion are corresponding with the signal waveform of the driving voltage of exporting from control section 113.To offer drive part 114 such as the alternating voltage of ac square-wave voltage or AC sine wave voltage.Therefore, utilize alternating voltage, drive part 114 can make piezo-activator 3 and touch panel part 2 slight vibration.
The method that input equipment 100b with aforementioned structure is controlled will be described below corresponding to the time period till pressing operation is identified that measures.
Fig. 9 shows and is used for explanation when pressing operation is identified in long-time section, the curve map of the relation between the driving voltage of panel compressing time section and piezo-activator.Figure 10 shows and is used for explanation when pressing operation is identified in short time period, the curve map of the relation between the driving voltage of panel compressing time section and piezo-activator.In Fig. 9 and Figure 10, upper curve illustrates the panel compressing time section of touch panel part 2 and the relation between the detected data value, and lower curve illustrates the signal waveform of the driving voltage that offers piezo-activator 3.The upper curve of Fig. 9 and Figure 10 illustrates the variation of detected data value along directions X.
Shown in the upper graph of Fig. 9 and Figure 10, before the front surface of the panel of touch panel part 2 was pressed, detected data value was 0 or approaches 0 in input operation.When the front surface of the panel of touch panel part 2 was pushed continuously, detected data value increased gradually.When the front surface of panel was continued to push, detected data value became stable.Corresponding to from pushing zero-time to the time period of pushing acknowledging time, the driving voltage that input equipment 100b will have the proper signal waveform offers piezo-activator 3.Therefore, input equipment 100b makes the operator feel the click feel corresponding with pressing operation.
In other words, when the time segment length till pressing operation is identified after pressing operation begins, promptly, shown in the lower graph of Fig. 9, become when having passed through long-time section before stable up to detected data value, after pressing operation was identified, the little amplitude ac square-wave voltage that input equipment 100b will have preset frequency offered piezo-activator 3, so that piezo-activator 3 and touch panel part 2 slight vibration.On the contrary, when the time period till pressing operation is identified after pressing operation begins in short-term, promptly, shown in the lower graph of Figure 10, detected data value becomes when stablizing in short time period, after pressing operation was identified, the large amplitude ac square-wave voltage that input equipment 100b will have preset frequency offered piezo-activator 3, so that piezo-activator 3 and 2 violent oscillatory motions of touch panel part.
Figure 11 shows the process flow diagram of control according to the control of the input equipment of second embodiment.
The input equipment 100b that touch panel part 2 was vibrated corresponding to the time period till pressing operation is identified after pressing operation begins, corresponding to the variation of detected data value, whether the operator is being pushed the front surface of panel and determining (step S1).
When the definite result in step S1 represented that the front surface of panel is being touched, input equipment 100b began to measure the time (step S2) as pushing zero-time.
After this, input equipment 100b monitors detected data value, and, corresponding to the steady state (SS) of detected data value, determine whether to confirm pressing operation (step S3).
When the judged result of step S3 is represented to have confirmed pressing operation, input equipment 100b stops to measure (step S4) to pushing the zero-time time period afterwards.
The driving voltage (step S5) that input equipment 100b decision is corresponding with the time period that measures that obtains in step S4.Input equipment 100b drives (step S6) with this driving voltage to piezo-activator 3.For example, the amplitude of the signal waveform that is inversely proportional to of input equipment 100b decision and the time period that measures.Input equipment 100b utilizes the driving voltage drive pressure electric actuator 3 that is inversely proportional to the time period that measures.
When input equipment 100b decision driving voltage, input equipment 100b can with time period of measuring with its predefined predetermined amount of time is compared and the decision driving voltage corresponding with comparative result.In other words, when time period that measures during than schedule time segment length, input equipment 100b is with predetermined little driving voltage drive pressure electric actuator 3.On the contrary, when the time period that measures than predetermined amount of time in short-term, input equipment 100b is with predetermined big driving voltage drive pressure electric actuator 3.
When the definite result in step S1 represented that panel is not touched, repeating step 1 was till judged result represents that panel is being touched.When the definite result in step S3 represented that pressing operation is not identified, repeating step S3 was till pressing operation is identified.
In Fig. 9, Figure 10 and Figure 11, when having passed through long-time section till pressing operation is identified, this expression operator has carried out pressing operation slightly.On the contrary, when having passed through short time period till pressing operation is identified, this expression operator has firmly carried out pressing operation.In such a manner, change corresponding with the magnitude of voltage after pressing operation begins, input equipment 100b measured the time period till pressing operation is identified after pressing operation begins, and made the dynamics of pressing operation relevant with the time period that measures.The driving voltage that input equipment 100b will have the signal waveform corresponding with the time period that measures offers piezo-activator 3, so that the operator feels the click feel corresponding with touch operation.
In Fig. 9 and example shown in Figure 10, ac square-wave voltage is offered piezo-activator 3.Certainly, also the AC sine wave voltage can be offered piezo-activator 3.
In the description in front, have the touch panel part 2 of the resistive film type touch panel of resistive film type Sensor section 111 as input equipment 100b.Touch panel part 2 can be used various types of touch panels, as capacitor type, optical type, ultrasonic type or electromagnetic induction type etc., so that the operator feels stroke sense and click feel.In other words, as long as sensor in any variation the detected signal (detected data value) till input operation is identified after input operation begins, can be used the sensor of any kind.
When touch panel part 2 was capacitive based touch panel, the operator was made of the electrically conducting transparent panel with the touch part of his or her finger touch.Make the circuit that applies voltage and detect electric current be positioned at framework the inside (under the outward flange that touches part).Apply constant voltage for the conduction panel.As operator during with the touch panel of his or her finger touch input equipment, the electric capacity of panel changes.The electric capacity that changes is detected as current value.
When touch panel part 2 was the touch panel of optical type, touching part was to be made of the transparent panel that glass or acryl resin etc. is made.To be arranged in framework the inside (under the outward flange that touches part) such as light-emitting device and the optical pickup apparatus of LED (LCD).Touch the front surface of part with the infrared radiation of matrix shape.By relative optical pickup apparatus receiving infrared-ray.As operator during with the front surface of the panel of touch input devices such as his or her finger, infrared ray is blocked.The ultrared variation that is blocked is detected as electric signal.
When touch panel part 2 is the touch panel of ultrasonic type, touches part and constitute by transparent panel.Transmitter and receiver are arranged in framework the inside (under the outward flange that touches part), so that they are relative with the Y direction along X.Oscillator produces surface acoustic wave on the front surface that touches part.As operator during with the front surface of the touch panel of his or her finger touch input equipment, the vibration that touches part is by finger.Thus, detect the delay of surface acoustic wave.
When touch panel part 2 is the touch panel of electromagnetic induction type, utilize to be included in the touch that constitutes by transparent panel and partly to go up the circuit that produces magnetic field and carry out input operation at interior pen type indicating device etc.At the dorsal part (at the dorsal part of operating surface) of panel, arrange many cell windings that magnetic field is detected, as Sensor section.When the operator utilized the front surface of indicating device contact touch panel, Sensor section detected the variation in magnetic field.

Therefore, the operator can learn the optimum operation to input equipment naturally.Therefore, the operator needn't operate this equipment with excessive power.Therefore, can alleviate the stress of the fatigue and the input operation aspect of finger.Therefore, can realize more friendly user interface for the operator.Because the operator is depended on the operability of input equipment to the impression of total system, therefore, the touch panel type input equipment is important interface portion.According to the present invention, improved the operability of touch panel type input equipment.In addition, the personnel that are unaccustomed to input operation can operate it reliably.
