The input device 100 is a pointing device that is connected to an information processing device such as a PC (Personal Computer) and operates the position of a pointer displayed on a PC monitor.

The input device 100 is disposed on the surface 1A of the object 1 such as a desk or a table. The surface 1A is a plane parallel to the XY plane in the XYZ coordinate system shown in FIGS. The user operates the position of the pointer by moving the input device 100 with respect to the surface 1A. Note that the surface 1A may not be flat, and may not be a horizontal plane.

The housing 110 is a mouse-type housing, and has an opening 110A for disposing the plate 120 on the surface (bottom surface in FIGS. 1 and 2) on the Z-axis negative direction side. The housing 110 holds a plate 120 disposed in the opening 110A, and the plate 120 is exposed on the surface of the housing 110 on the Z axis negative direction side.

A wheel 111 is provided on the surface on the Z-axis positive direction side of the housing 110, and a left button 112 and a cancel button 113 are provided on a side surface on the X-axis positive direction side. Further, an LED 115 and a sensor 116 are provided on the Y axis positive direction side of the plate 120 on the surface of the housing 110 on the Z axis negative direction side.

Further, the control device 200 is mounted on the wall portion 110B inside the housing 110. The wall part 110B is located on the positive side of the Z axis of the opening part 110A and extends in a direction substantially parallel to the XY plane.

The drive control unit included in the control device 200 drives the vibration element 140 with a drive signal that causes the natural vibration of the ultrasonic band. The drive control of the vibration element 140 by the drive control unit of the control device 200 will be described later with reference to FIGS.

The casing 110 has a shape that fits in the palm of the user except on the side where the opening 110A is formed.

When the input device 100 is connected to a PC, the wheel 111 is an operation unit used when scrolling up and down an image displayed on a PC monitor, for example.

The left button 112 is a button that is pressed when performing selection or determination, for example. Although not shown in FIGS. 1 and 2, the input device 100 may have a right button provided on the side surface on the X-axis negative direction side. The right button is, for example, a button that is pressed when displaying a menu on the monitor.

The cancel button 113 is a button that is pressed when driving the vibration element 140 is stopped. The input device 100 causes the vibration element 140 to vibrate with a drive signal that causes the natural vibration of the ultrasonic band. The input device 100 switches the on / off of the vibration element 140 according to the position of the pointer displayed on the monitor and the temporal change in the position, but when the cancel button 113 is pressed, the vibration element 140 is forcibly turned off. To be.

The cable 114 is a cable for connecting the input device 100 to a PC, and has, for example, a USB (Universal Serial Bus) connector at the tip.

The LED 115 and the sensor 116 are an example of a movement detection unit that detects a movement direction and a movement amount of the input device 100. The sensor 116 is, for example, an image sensor, and detects a moving direction and a moving amount of the input device 100 by reading a pattern on the surface of an object irradiated with laser light from the LED 115.

The plate 120 is bonded to the housing 110 with a double-sided tape 130 so as to be exposed to the surface on the Z-axis negative direction side from an opening 110A provided on the surface on the Z-axis negative direction side of the housing 110. Since the plate 120 is located on the bottom surface of the input device 100, it can be handled as a bottom plate or a bottom panel.

The plate 120 is a thin flat plate member that is rectangular in plan view, and is made of metal, resin, ceramic, or the like. A surface 120 </ b> A (surface on the negative Z-axis direction side) 120 </ b> A of the plate 120 is a surface that contacts the surface 1 </ b> A of the object 1.

In the plate 120, the vibration element 140 is bonded to the surface on the Z axis positive direction side, and four sides in the XY plan view are bonded to the casing 110 by the double-sided tape 130. The double-sided tape 130 only needs to be able to bond the four sides of the plate 120 to the housing 110, and does not need to be rectangular in a plan view.

In addition, another panel or a protective film may be provided on the surface 120A of the plate 120. In such a case, the surface 120A of the plate 120 comes into contact with the surface 1A of the object 1 via another panel or a protective film.

The plate 120 vibrates when the vibration element 140 is driven in a state where the vibration element 140 is bonded to the surface on the positive side of the Z axis. In the embodiment, the plate 120 is vibrated at the natural vibration frequency of the plate 120 to generate a standing wave in the plate 120. However, since the vibration element 140 is bonded to the plate 120, it is actually preferable to determine the natural vibration frequency in consideration of the weight of the vibration element 140 and the like.

The vibration element 140 is bonded along the short side extending in the X-axis direction on the Y-axis negative direction side of the surface of the plate 120 on the Z-axis positive direction side. The vibration element 140 may be an element that can generate vibrations in an ultrasonic band. For example, an element including a piezoelectric element such as a piezoelectric element can be used. A piezoelectric element is an element that vibrates in a three-dimensional direction.

The vibration element 140 is driven by a drive signal output from the drive control unit of the control device 200. The amplitude (intensity) and frequency of vibration generated by the vibration element 140 are set by the drive signal. Further, on / off of the vibration element 140 is controlled by a drive signal.

In addition, an ultrasonic band means a frequency band about 20 kHz or more, for example. In the input device 100 according to the embodiment, the frequency at which the vibration element 140 vibrates is equal to the frequency of the plate 120, so that the vibration element 140 is driven by a drive signal so as to vibrate at the natural frequency of the plate 120. .

In the input device 100 configured as described above, when the pointer touches a predetermined symbol displayed on the monitor or a predetermined GUI operation unit or the like, the drive control unit of the control device 200 drives the vibration element 140 to move the plate 120. Vibrate at ultrasonic frequency. The frequency of this ultrasonic band is a resonance frequency of a resonance system including the plate 120 and the vibration element 140 and causes the plate 120 to generate a standing wave.

The input device 100 provides a tactile sensation to the user through the casing 110 by generating a standing wave in the ultrasonic band.

Next, the standing wave generated in the plate 120 will be described with reference to FIG.

FIG. 3 is a diagram showing a wave front formed in parallel to the short side of the plate 120 among the standing waves generated in the plate 120 by the natural vibration of the ultrasonic band, and FIG. B) is a perspective view. 3A and 3B, XYZ coordinates similar to those in FIGS. 1 and 2 are defined. In FIGS. 3A and 3B, the amplitude of the standing wave is exaggerated for easy understanding. Further, the vibration element 140 is omitted in FIGS.

Using the Young's modulus E, density ρ, Poisson's ratio δ, long side dimension l, thickness t of the plate 120 and the standing wave period k existing in the long side direction, the natural frequency (resonance) of the plate 120 is obtained. The frequency f is expressed by the following equations (1) and (2). Since the standing wave has the same waveform in units of ½ period, the number of periods k takes values in increments of 0.5, which are 0.5, 1, 1.5, 2.

Note that the coefficient α in Expression (2) collectively represents coefficients other than k ² in Expression (1).

3A and 3B are waveforms when the number of periods k is 5, as an example. For example, when Gorilla (registered trademark) glass having a long side length l of 70 mm, a short side length of 40 mm, and a thickness t of 0.7 mm is used as the plate 120, the period number k is 5. In addition, the natural frequency f is 33.5 [kHz]. In this case, a drive signal having a frequency of 33.5 [kHz] may be used.

The plate 120 is a flat plate member. When the vibration element 140 (see FIGS. 1 and 2) is driven to generate the natural vibration of the ultrasonic band, the plate 120 is shown in FIGS. In this way, a standing wave is generated on the surface.

Here, a description will be given of a form in which one vibration element 140 is bonded along the short side extending in the X-axis direction on the Y-axis negative direction side on the surface of the plate 120 on the Z-axis positive direction side. Two vibration elements 140 may be used. When two vibration elements 140 are used, another vibration element 140 is bonded to the surface on the Z-axis positive direction side of the plate 120 along the short side extending in the X-axis direction on the Y-axis positive direction side. Good. In this case, the two vibration elements 140 may be arranged so as to be axially symmetric with respect to a center line parallel to the two short sides of the plate 120.

In addition, when the two vibration elements 140 are driven, they may be driven with the same phase when the number of periods k is an integer, and with opposite phases when the number of periods k is a decimal (a number including an integer part and a decimal part). It can be driven by.

FIG. 5 is a block diagram illustrating a configuration of a main part in the main body 11 of the computer system 10. The main body 11 includes a CPU 21 connected by a bus 20, a memory unit 22 including a RAM or a ROM, a disk drive 23 for the disk 17, and a hard disk drive (HDD) 24.

The display panel 12 may be connected to the CPU 21 via a known graphic interface (not shown) that processes input / output image data.

Note that the computer system 10 is not limited to the configuration shown in FIGS. 4 and 5, and various well-known elements may be added or alternatively used.

FIG. 6 is a diagram illustrating an internal configuration of the main body 11 of the PC according to the embodiment.

The main body unit 11 includes a control unit 510, an application processor 520, a communication unit 530, an amplitude data output unit 540, and a memory 550. Further, a display panel 12 and a driver IC 12B are connected to the main body 11. The control unit 510, the application processor 520, and the amplitude data output unit 540 represent functional blocks realized by a CPU (Central Processing Unit) chip included in the main body unit 11.

In FIG. 6, the display panel 12, the input device 100, and the modem 15 (see FIG. 4) are omitted. Here, the driver IC 12B, the control unit 510, the application processor 520, the communication unit 530, the amplitude data output unit 540, and the memory 550 will be described.

The driver IC 12B is connected to the display panel 12, inputs the drawing data output from the application processor 520 to the display panel 12, and causes the display panel 12 to display an image based on the drawing data. As a result, a GUI operation unit or an image based on the drawing data is displayed on the display panel 12.

The control unit 510 is a control unit that controls all processes executed by the main body unit 11. Here, in particular, a method of obtaining the position of the pointer displayed on the display panel 12 among the functions of the control unit 510 will be described.

The control unit 510 obtains the position of the pointer displayed on the display panel 12 based on the data representing the movement amount and movement direction of the input device 100 input from the input device 100 via the communication unit 530. Control unit 510 is an example of a pointer control unit.

Here, the position of the symbol in the text displayed on the display panel 12 is specified by, for example, an OS (Operating System) installed in the PC. Here, the symbol is a generic name including characters, numbers, pictograms, emoticons, and other symbols. The characters are characters used for writing hiragana, katakana, kanji, alphabets, and other languages.

In addition, among the symbols in the text displayed on the display panel 12, the position of the symbol for which the hyperlink is set is specified by the OS installed in the PC. A symbol for which a hyperlink is set is an example of a predetermined symbol.

Also, the OS determines whether the pointer is touching a symbol for which a hyperlink is set. When the pointer touches a symbol for which a hyperlink is set, the OS outputs a signal indicating that the pointer is touched.

It is assumed that such an OS is installed in the main body unit 11 and executed by the control unit 510.

Application processor 520 performs processing for executing various applications of main unit 11.

The communication unit 530 is an interface connected to the cable 114 when the main body unit 11 and the input device 100 are connected by the cable 114. Further, when the main body unit 11 and the input device 100 are connected by wireless communication, the communication unit 530 is a communication unit for short-range communication such as Bluetooth (registered trademark), for example.

The amplitude data output unit 540 generates amplitude data representing the amplitude value of the drive signal used for driving the vibration element 140. The amplitude value is set according to the degree of temporal change in the position of the input device 100.

Further, the drive control device 300 according to the embodiment vibrates the plate 120 in order to change the dynamic friction force applied to the plate 120 when the input device 100 moves along the surface 1A of the object 1. Since the dynamic friction force is generated when the plate 120 is moving, the amplitude data output unit 540 is for causing the vibration element 140 to vibrate when the moving speed of the input device 100 exceeds a predetermined threshold speed. Outputs amplitude data.

Therefore, the amplitude value represented by the amplitude data output from the amplitude data output unit 540 is zero when the moving speed is less than the predetermined threshold speed, and is predetermined according to the moving speed when the moving speed is equal to or higher than the predetermined threshold speed. Is set to the amplitude value.

Also, the amplitude data output unit 540 outputs amplitude data when the control unit 510 touches a predetermined symbol that should generate vibration or is within a predetermined area.

When the control unit 510 outputs a signal indicating that the pointer is touching the symbol for which the hyperlink is set, the amplitude data output unit 540 outputs the amplitude data of the vibration pattern assigned to the hyperlink. Output.

Also, the amplitude data output unit 540 outputs amplitude data of the vibration pattern assigned to the GUI operation unit or the like when the pointer is inside the display area such as the GUI operation unit or the like.

Here, the position on the display panel 12 such as a GUI operation unit to be displayed on the display panel 12 and an area for displaying other images is specified by area data representing the area. The area data exists for areas representing all GUI operation units and the like displayed on the display panel 12 in all applications.

The amplitude data output unit 540 determines whether or not the position of the pointer input from the control unit 510 is within a predetermined region where vibration is to be generated, using the region data.

Data that associates data representing the type of application, area data representing a GUI operation unit or the like on which an operation input is performed, and pattern data representing a vibration pattern is stored in the memory 550.

The amplitude data output unit 540 outputs the amplitude data generated as described above to the input device 100 via the communication unit 530. As a result, in the input device 100, the vibration element 140 is driven by a drive signal based on the amplitude data.

Further, the memory 550 stores data and programs necessary for the application processor 520 to execute the application, data and programs necessary for the communication processing by the communication unit 530, and the like.

FIG. 7 is a diagram illustrating a configuration of the input device 100 according to the embodiment.

The input device 100 includes a vibration element 140, an amplifier 141, a cancel button 113, and a control device 200. The control device 200 includes a control unit 210, a movement detection unit 220, a communication unit 230, a drive control unit 240, a sine wave generator 310, and an amplitude modulator 320. In FIG. 7, the components of the input device 100 other than these are omitted.

The control unit 210, the movement detection unit 220, and the drive control unit 240 are realized by, for example, an IC chip. Note that the control unit 210, the movement detection unit 220, and the drive control unit 240 may be configured with one IC chip, or may be configured with different IC chips.

The amplifier 141 is disposed between the amplitude modulator 320 and the vibration element 140 and drives the vibration element 140 by amplifying the drive signal output from the amplitude modulator 320.

The control unit 210 transmits data representing the operation amount of the wheel 111 to the main body unit 11 through the communication unit 230. Further, the control unit 210 controls the lighting of the LED 115.

The movement detection unit 220 detects the movement direction and movement amount of the input device 100 based on data input from the sensor 116. When an image sensor is used as the sensor 116, the movement detection unit 220 analyzes an image input from the sensor 116 and detects a movement direction and a movement amount of the input device 100. When the apparatus 100 is connected with the cable 114, the interface is connected to the cable 114. In addition, when the main body unit 11 and the input device 100 are connected by wireless communication, the communication unit 230 is a communication unit for near field communication such as Bluetooth, for example.

The communication unit 230 transmits data representing the operation amount of the wheel 111 output from the control unit 210 to the main body unit 11. The communication unit 230 transmits data representing the movement direction and the movement amount detected by the movement detection unit 220 to the main body unit 11. The communication unit 230 transmits the drive signal transmitted from the main body unit 11 to the drive control unit 240.

The drive control unit 240 drives the vibration element 140 using the drive signal transmitted from the main body unit 11. The drive signal is data in which amplitude data for modulating the amplitude of the sine wave signal of the ultrasonic band input from the sine wave generator 310 is arranged in time series. The amplitude data is data in which data representing the amplitude of the modulated drive signal is arranged in time series.

The cancel button 113 is an operation unit that forcibly turns off the driving of the vibration element 140 by the drive control unit 240. When the cancel button 113 is pressed by the user, the amplitude data output from the drive control unit 240 is set to zero. Further, instead of setting the amplitude data output by the drive control unit 240 to zero, the drive control unit 240 may not output the amplitude data.

The sine wave generator 310 generates a sine wave necessary for generating a drive signal for vibrating the plate 120 at the natural frequency. For example, when the plate 120 is vibrated at a natural frequency f of 33.5 [kHz], the frequency of the sine wave is 33.5 [kHz]. The sine wave generator 310 inputs an ultrasonic band sine wave signal to the amplitude modulator 320.

The amplitude modulator 320 modulates the amplitude of the sine wave signal input from the sine wave generator 310 using the amplitude data input from the drive control unit 240 to generate a drive signal. The amplitude modulator 320 modulates only the amplitude of the sine wave signal in the ultrasonic band input from the sine wave generator 310, and generates the drive signal without modulating the frequency and phase.

Therefore, the drive signal output by the amplitude modulator 320 is an ultrasonic band sine wave signal obtained by modulating only the amplitude of the ultrasonic band sine wave signal input from the sine wave generator 310. Note that when the amplitude data is zero, the amplitude of the drive signal is zero. This is equivalent to the amplitude modulator 320 not outputting a drive signal.

FIG. 8 is a diagram illustrating a first operation example of the input device 100 according to the embodiment. FIG. 9 shows a vibration pattern of the vibration element 140 corresponding to the first operation example shown in FIG.

FIG. 8 shows text displayed on the display panel 12. A hyperlink is set in a part of the text. The text shown in FIG. 8 is quoted from the English version of Wikipedia (Olympic Games (May 26, 2015, 2:10 UTC) Wikipedia: The Free Encyclopedia. Retrieved from http://en.wikipedia.org/wiki / Olympic_Games).

In FIG. 8, a word for which no hyperlink is set is shown in black, and a word for which a hyperlink is set is shown in gray. The pointer 12A moves in the image displayed on the display panel 12 when the user moves the input device 100 on the surface 1A of the object 1 (see FIGS. 1 and 2).

For example, assume that the pointer 12A touches “Ancient” of the word “Ancient Olympic Games” for which a hyperlink is set. More specifically, as indicated by an upward arrow, the pointer 12A approaches from the lower side of “Ancient” and starts to touch at time t11.

When the pointer 12A is operated in this way, the vibration pattern of the drive signal for driving the vibration element 140 changes from zero to A1 at time t11 as shown in FIG. 9, and a very short time has elapsed. This is a vibration pattern in which the amplitude becomes zero at time t12.

The vibration pattern shown in FIG. 9 is represented by, for example, data in which data representing amplitudes are arranged in time series. That is, the vibration pattern shown in FIG. 9 is given by envelopes of a plurality of amplitude data representing amplitudes arranged in time series.

When the vibration element 140 is driven with the vibration pattern as shown in FIG. 9, the natural vibration of the ultrasonic band is generated on the plate 120 at the time t11, and the natural vibration of the ultrasonic band is not generated at the time t12.

When natural vibration of the ultrasonic band is generated in the plate 120, an air layer is interposed between the plate 120 and the surface 1A of the object 1 (see FIGS. 1 and 2) due to the squeeze effect, and the dynamic friction coefficient of the plate 120 with respect to the surface 1A. Decreases.

Further, when switching from the state in which the natural vibration of the ultrasonic band is generated in the plate 120 to the state in which the natural vibration of the ultrasonic band is not generated, the air layer disappears, and thus the dynamic friction coefficient of the plate 120 with respect to the surface 1A increases. .

Therefore, the user who operates the input device 100 has a feeling that the input device 100 becomes slippery with respect to the surface 1A due to the decrease in the dynamic friction force at time t11, and the input device 100 is exposed to the surface due to the increase in the dynamic friction force at time t12. Get a feel that is less slippery than 1A.

For this reason, when the pointer 12A comes into contact with a word for which a hyperlink is set at time t11, the input device 100 becomes slippery with respect to the surface 1A, and vibration does not occur at time t12 immediately after time t11. Then, due to the increase of the dynamic friction force, the input device 100 is less likely to slip with respect to the surface 1A.

Therefore, when the pointer 12A comes into contact with a word for which a hyperlink is set, the input device 100 easily slides on the surface 1A for a moment, and immediately thereafter (time t12), the input device 100 slips on the surface 1A. By becoming difficult, the user's hand is provided with a tactile sensation as if the input device 100 hit the projection. Thereby, the user can perceive with tactile sensation that the pointer 12A has reached the word for which the hyperlink is set.

In the drive control of the vibration element 140 as described above, the amplitude data output unit 540 of the main body 11 (see FIG. 4) of the computer system 10 transmits the amplitude data stored in the memory 550 to the input device 100. Then, the drive control unit 240 of the input device 100 outputs amplitude data to the amplitude modulator 320, and the amplitude modulator 320 amplitude-modulates the sine wave signal of the ultrasonic band output from the sine wave generator 310 with the amplitude data. Thus, a drive signal is generated, and the vibration element 140 is driven by the drive signal.

Note that time t12 represents the timing at which the driving of the vibrating element 140 is turned off after the vibrating element 140 is driven at time t11. That is, the vibration element 140 is turned on during a period from time t11 to time t12. Thus, the period during which the vibration element 140 is turned on may be set as appropriate according to the application. For this reason, the timing of the time t12 with respect to the time t11 is determined by the period during which the vibration element 140 is turned on.

Next, the control processing of the amplitude data and the amplitude data output unit 540 will be described with reference to FIGS.

FIG. 10 is a diagram showing data stored in the memory 550.

The data stored in the memory 550 is data in which data representing the type of application is associated with pattern data representing a vibration pattern.

· Shows application ID (Identification) as data indicating the type of application. P1 to P5 are shown as pattern data representing the vibration pattern. The pattern data representing the vibration pattern includes data representing the amplitude, and represents, for example, the vibration pattern shown in FIG.

Note that the application represented by the application ID includes any application that can be used on a smartphone terminal or a tablet computer.

FIG. 11 is a flowchart showing processing executed by the amplitude data output unit 540. The processing shown in FIG. 11 can be executed by installing an application program for using the input device 100 in the computer system 10 main body 11 (see FIG. 6).

The OS (Operating System) of the main body 11 executes control for driving the main body 11 at every predetermined control cycle. For this reason, the amplitude data output unit 540 performs calculation every predetermined control period.

Also, the OS of the main body 11 determines whether or not the pointer 12A touches a word for which a hyperlink is set. When the pointer 12A touches a word for which a hyperlink is set, the OS outputs a signal (hyperlink contact signal) indicating that the pointer is touched. Such processing is executed by the control unit 510 of the main body unit 11. Control unit 510 inputs a hyperlink contact signal to amplitude data output unit 540.

The amplitude data output unit 540 starts the process when the main unit 11 is turned on.

The amplitude data output unit 540 determines whether a hyperlink contact signal is input (step S1).

When the amplitude data output unit 540 determines that the hyperlink contact signal is input in step S1 (S1: YES), the amplitude data output unit 540 reads the amplitude data from the memory 550 and sets the amplitude value (step S2A).

The amplitude data output unit 540 outputs the amplitude data in which the amplitude value is set in step S2A (step S3). As a result, amplitude data is transmitted from the amplitude data output unit 540 to the input device 100, and the amplitude modulator 320 modulates the amplitude of the sine wave output from the sine wave generator 310 to generate a drive signal, and the vibration element 140 is driven.

On the other hand, if it is determined in step S1 that no hyperlink contact signal is input (S1: NO), the amplitude data output unit 540 sets the amplitude value to zero (step S2B).

As a result, the amplitude data output unit 540 outputs amplitude data having an amplitude value of zero, and the amplitude modulator 320 generates a drive signal in which the amplitude of the sine wave output from the sine wave generator 310 is modulated to zero. . For this reason, in this case, the vibration element 140 is not driven.

As described above, when the pointer 12A touches a word for which a hyperlink is set, the user's hand is provided with a tactile sensation as if the input device 100 hit the protrusion. Thereby, the user can perceive with tactile sensation that the pointer 12A has reached the word for which the hyperlink is set.

Here, an example of the operation of driving the vibration element 140 when the pointer 12A reaches the word for which the hyperlink is set has been described. However, the pointer 12A can be set to any word other than the word for which the hyperlink is set. The vibration element 140 may be driven when the angle reaches.

FIG. 12 is a diagram illustrating a second operation example of the input device 100 according to the embodiment. FIG. 13 shows a vibration pattern of the vibration element 140 corresponding to the second operation example shown in FIG.

FIG. 12 shows icons displayed on the display panel 12.

For example, the case where the pointer 12A passes through the icon 12C will be described. More specifically, as indicated by a right-pointing arrow, it is assumed that the pointer 12A starts approaching and touching from the left side of the icon 12C at time t21 and finishes touching the icon 12C at time t22.

When the pointer 12A is thus operated, the vibration pattern of the drive signal for driving the vibration element 140 changes from zero to B1 at time t21 and zero at time t12, as shown in FIG. The vibration pattern becomes

When the vibration element 140 is driven in this way, the natural vibration of the ultrasonic band is generated on the plate 120 at the time t21, and the natural vibration of the ultrasonic band is not generated at the time t22.

Therefore, when the pointer 12 enters the display area of the icon 12C at time t21, the input device 100 becomes slippery with respect to the surface 1A, and when the pointer 12 goes out of the display area of the icon 12C at time t22. Due to the increase of the dynamic friction force, the input device 100 is less likely to slip with respect to the surface 1A.

Therefore, when the pointer 12 enters the display area of the icon 12C, the input device 100 becomes slippery with respect to the surface 1A, and a tactile sensation that makes the input device 100 slippery is provided to the user's hand. . As a result, the user can perceive the tactile sensation that the pointer 12 has entered the display area of the icon 12C.

Further, even when the pointer 12 is within the display area of the icon 12C, the input device 100 becomes slippery with respect to the surface 1A, and a tactile sensation that makes the input device 100 slippery is provided to the user's hand. . Thereby, the user can perceive by touch that the pointer 12 is in the display area of the icon 12C.

Further, when the pointer 12 goes out of the display area of the icon 12C, the input device 100 is difficult to slip with respect to the surface 1A, so that the input device 100 hits the protrusion on the user's hand. A tactile sensation is provided. As a result, the user can perceive the tactile sensation that the pointer 12 has left the display area of the icon 12C.

In the drive control of the vibration element 140 as described above, the amplitude data output unit 540 of the main body 11 (see FIG. 4) of the computer system 10 transmits the amplitude data stored in the memory 550 to the input device 100. Then, the drive control unit 240 of the input device 100 inputs the amplitude data to the amplitude modulator 320, and the amplitude modulator 320 generates a drive signal by amplitude-modulating the sine wave signal of the ultrasonic band with the amplitude data. The vibration element 140 is driven by this drive signal. As described above, drive control of the vibration element 140 is realized.

Next, the control process of the amplitude data and amplitude data output unit 540 will be described with reference to FIGS.

FIG. 14 is a diagram showing data stored in the memory 550.

The data stored in the memory 550 is data in which data representing the type of application, area data representing the display area of the icon 12C, and pattern data representing the vibration pattern are associated with each other. In all applications, the area data exists for all GUI operation units displayed on the display panel 12, an area for displaying an image, or an area representing the entire page.

· Shows the application ID as data indicating the type of application. As the area data, equations f1 to f5 representing the coordinate values of the area in which the GUI operation unit or the like where the operation input is performed are displayed are shown. Further, Q1 to Q5 are shown as pattern data representing the vibration pattern. The pattern data representing the vibration pattern includes data representing the amplitude, and represents, for example, the vibration pattern shown in FIG.

FIG. 15 is a flowchart showing processing executed by the amplitude data output unit 540.

Further, the OS of the main body 11 determines whether the pointer 12A is touching the display area of the icon 12C. When the pointer 12A touches the display area of the icon 12C, the OS outputs a signal indicating that the pointer 12A is touching (icon contact signal). Such processing is executed by the control unit 510 of the main body unit 11. Control unit 510 inputs an icon contact signal to amplitude data output unit 540.

The amplitude data output unit 540 acquires position data indicating the current position of the pointer 12A and area data associated with the current application type (step S21).

The amplitude data output unit 540 determines whether or not the current position of the pointer 12A is within the region represented by any region data (step S22).

If the amplitude data output unit 540 determines in step S22 that the current position of the pointer 12A is within the region represented by any of the region data (S22: YES), the amplitude data output unit 540 reads the amplitude data from the memory 550 and determines the amplitude. A value is set (step S23A).

Here, for example, if the current position of the pointer 12A is within the display area of the icon 12C, the amplitude data included in the vibration pattern associated with the area data of the icon 12C is read and the amplitude value is set. .

The amplitude data output unit 540 outputs the amplitude data set with the amplitude value in step S23A (step S24). As a result, the amplitude data is transmitted from the amplitude data output unit 540 to the input device 100, and the amplitude modulator 320 modulates the amplitude of the sine wave output from the sine wave generator 310 to generate a drive signal, and the drive signal Thus, the vibration element 140 is driven.

On the other hand, if it is determined in step S22 that the current position of the pointer 12A is not within the region represented by any of the region data (S22: NO), the amplitude data output unit 540 sets the amplitude value to zero. (Step S23B).

As a result, the amplitude data output unit 540 outputs amplitude data whose amplitude value is zero in step S24, and the amplitude modulator 320 is a drive signal obtained by modulating the amplitude of the sine wave output from the sine wave generator 310 to zero. Is generated. In this case, the vibration element 140 is not driven.

As described above, when the pointer 12 enters the icon 12C display area, the user's hand is provided with a tactile sensation that makes the input device 100 slippery, and the user moves the pointer 12 into the icon 12C display area. You can perceive that you have entered.

Further, even when the pointer 12 is within the display area of the icon 12C, a tactile sensation that makes the input device 100 easy to slip is provided, so that the user perceives that the pointer 12 is in the display area of the icon 12C. it can.

Further, when the pointer 12 goes out of the display area of the icon 12C, the user's hand is provided with a tactile sensation as if the input device 100 hit the protrusion. It can be perceived by touch that the user has left the display area.

In the second operation example, the mode in which the vibration element 140 is switched on / off when the pointer 12A enters or exits the icon display area has been described. The vibration element 140 may be driven according to the positional relationship with the pointer 12A.

16 and 17 are diagrams illustrating a third operation example of the input device 100 according to the embodiment. FIG. 18 is a diagram illustrating a vibration pattern of the vibration element 140 corresponding to the third operation example illustrated in FIG. 16.

FIG. 16 illustrates a case where the image on the display panel 12 is scrolled.

The image on the display panel 12 can be scrolled by moving the scroll bar 12D shown in FIG. 16 up and down. Here, while pressing the Ctrl key of the keyboard 13 (see FIG. 4), input is made to draw a circle. A case where the image on the display panel 12 is scrolled by operating the device 100 will be described.

When the input device 100 is operated to draw a circle as shown in FIG. 17 while pressing the Ctrl key, the image on the display panel 12 can be scrolled.

For example, when the input device 100 is operated so that the pointer 12A draws a circle clockwise as shown in FIG. 17 while pressing the Ctrl key, the image on the display panel 12 can be scrolled upward.

Suppose that the pointer 12A starts to move in a clockwise circle at time t31 while the Ctrl key is pressed, and stops at time t32.

When the pointer 12A is operated in this way, the vibration pattern of the drive signal that drives the vibration element 140 is as shown in FIG. At time t31, the amplitude changes from zero to C1, and immediately after that, the amplitude becomes zero. Then, every time a predetermined operation amount is reached, the vibration element 140 is driven with the amplitude C2 (<C1).

When the vibration element 140 is driven in this way, the plate 120 is subjected to a natural vibration of the ultrasonic band at the time t31 when the scroll operation is started, and reaches a predetermined operation amount until the scroll operation is finished at the time t32. Each time it reaches, the vibration element 140 is driven with the amplitude C2 (<C1).

When the vibration element 140 is driven with the amplitude C1 at the time t31 when the scroll operation is started and the vibration element 140 is turned off immediately after that, the input device 100 becomes slippery from the slippery state with respect to the surface 1A. Thus, the user's hand is provided with a tactile sensation as if the input device 100 hit the projection. As a result, the user can perceive that the scrolling has started by tactile sensation.

If the scroll operation is continued, the vibration element 140 is driven with the amplitude C2 every time the operation amount reaches a predetermined amount. Since the amplitude C2 is smaller than the amplitude C1, every time the operation amount reaches a predetermined amount, the user's hand is provided with a tactile sensation as if the input device 100 hit a small protrusion. Thereby, the user can perceive with tactile sensation that the operation amount of the scroll operation has reached a predetermined amount.

Note that FIG. 17 illustrates the case where the image on the display panel 12 can be scrolled upward by moving the pointer 12A clockwise, but the pointer 12A draws a circle counterclockwise while pressing the Ctrl key. When the input device 100 is operated as described above, the image on the display panel 12 can be scrolled downward.

In the drive control of the vibration element 140 as described above, the amplitude data output unit 540 of the main body 11 (see FIG. 4) of the computer system 10 transmits the amplitude data stored in the memory 550 to the input device 100. Then, the drive control unit 240 of the input device 100 outputs the amplitude data to the amplitude modulator 320, and the amplitude modulator 320 generates a drive signal using the amplitude data, whereby drive control of the vibration element 140 is realized. .

Next, the control processing of the amplitude data and amplitude data output unit 540 will be described with reference to FIGS. 19 and 20.

FIG. 19 is a diagram showing data stored in the memory 550.

The data stored in the memory 550 is data in which data representing the type of application, operation amount data representing a predetermined operation amount, and pattern data representing a vibration pattern are associated with each other. The manipulated variable data is data representing a predetermined manipulated variable that generates a vibration having an amplitude C2 shown in FIG.

· Shows the application ID as data indicating the type of application. As the operation amount data, equations S1 to S5 representing a predetermined operation amount for generating the vibration with the amplitude C2 are shown. In addition, R1 to R5 are shown as pattern data representing the vibration pattern. The pattern data representing the vibration pattern includes data representing the amplitude, and represents, for example, the vibration pattern having the amplitudes C1 and C2 illustrated in FIG.

FIG. 20 is a flowchart showing processing executed by the amplitude data output unit 540.

The amplitude data output unit 540 determines whether or not the Ctrl key is pressed (step S31). This is because if the input device 100 is operated so that the pointer 12A draws a circle while the Ctrl key is pressed, the image on the display panel 12 can be scrolled upward or downward. Note that the process of step S31 is repeatedly executed until it is determined that the Ctrl key is pressed.

When the amplitude data output unit 540 determines that the Ctrl key is pressed (S31: YES), the amplitude data output unit 540 determines whether scrolling has started (step S32). Whether or not scrolling has started can be determined based on whether or not the position of the pointer 12A has moved. Note that the process of step S32 is repeatedly executed until it is determined that scrolling has started.

The amplitude data output unit 540 sets the amplitude value at the start of scrolling (step S33). For example, the amplitude C1 shown in FIG. 18 is set.

The amplitude data output unit 540 outputs the amplitude data set with the amplitude value in step S33 (step S34). As a result, amplitude data is transmitted from the amplitude data output unit 540 to the input device 100, and the amplitude modulator 320 modulates the amplitude of the sine wave output from the sine wave generator 310 to generate a drive signal, and the vibration element 140 is driven. For example, the vibration element 140 is driven with the amplitude C1 shown in FIG.

The amplitude data output unit 540 determines whether or not the operation amount of the scroll operation has reached a predetermined operation amount (step S35). The predetermined operation amount is determined in advance by operation amount data shown in FIG.

When it is determined that the predetermined operation amount has been reached (S35: YES), the amplitude data output unit 540 reads the amplitude data from the memory 550 and sets the amplitude value (step S36A).

Here, for example, if the operation amount of the pointer 12A has reached a predetermined operation amount after the scroll operation is started, the amplitude data included in the vibration pattern associated with the application ID is read and the amplitude value is Is set.

The amplitude data output unit 540 outputs the amplitude data for which the amplitude value is set in step S36A (step S37). As a result, amplitude data is transmitted from the amplitude data output unit 540 to the input device 100, and the amplitude modulator 320 modulates the amplitude of the sine wave output from the sine wave generator 310 to generate a drive signal, and the vibration element 140 is driven.

On the other hand, if it is determined in step S35 that the predetermined operation amount has not been reached (S35: NO), the amplitude data output unit 540 sets the amplitude value to zero (step S36B).

When the process of step S36A or S36B is completed, the amplitude data output unit 540 determines whether or not the scroll operation is completed (step S38). The scrolling operation ends when the position of the pointer 12A has not moved.

If the amplitude data output unit 540 determines that the scroll operation has not ended (S38: NO), the flow returns to step S35.

On the other hand, if the amplitude data output unit 540 determines that the scroll operation has ended (S38: YES), the series of flows ends (end).

As described above, when the scroll operation is started, the vibration element 140 is driven with a large amplitude, and immediately after that, the vibration element 140 is turned off. Thus, the user's hand is provided with a tactile sensation as if the input device 100 hit a relatively large protrusion. As a result, the user can perceive that the scrolling has started by tactile sensation.

Further, if the scroll operation is continued, the vibration element 140 is driven with a small amplitude every time the operation amount reaches the predetermined amount. Therefore, every time the operation amount reaches the predetermined amount, the user's hand holds the input device. A tactile sensation such that 100 hits a relatively small protrusion is provided. Thereby, the user can perceive with tactile sensation that the operation amount of the scroll operation has reached a predetermined amount.

The amplitude C1 and the amplitude C2 are not limited to the case where the amplitude C1 is larger than the amplitude C2, as described above, and the amplitude C1 and the amplitude C2 may be equal, or the amplitude C2 may be larger than the amplitude C1. .

In the third operation example of the embodiment, when the scroll operation is performed by operating the input device 100 so as to draw a circle with the Ctrl key pressed, the scroll operation is started and a predetermined operation is performed. The mode in which the vibration element 140 is driven when the amount is reached has been described. However, when the scroll bar 12D shown in FIG. 16 is moved by the pointer 12A, the vibration element 140 may be driven to provide a tactile sensation every time the amount of movement of the scroll bar 12D reaches a predetermined amount.

In the third operation example, the mode in which the vibration element 140 is turned on / off when the scroll operation is performed using the input device 100 has been described. However, the vibration element 140 is turned on / off during an operation other than the scroll operation. You may do it.

As described above, since the input device 100 according to the embodiment generates the natural vibration of the ultrasonic band on the plate 120 according to the position of the pointer 12A and the degree of movement of the position, it is favorable for the user by using the squeeze effect. A tactile sensation can be provided.

Due to the squeeze effect, a very thin air layer is interposed between the plate 120 and the surface 1A of the object 1, so that when the input device 100 is moved with respect to the surface 1A, the dynamic friction force decreases.

When the vibration element 140 is turned off from the state in which the dynamic friction force is reduced in this way, an air layer is not interposed between the plate 120 and the surface 1A of the object 1, so that the input device 100 is difficult to slip with respect to the surface 1A. Thus, it is possible to provide the user with a tactile sensation as if the input device 100 hit the convex portion.

As described above, according to the embodiment, it is possible to provide the input device 100 that can provide a good tactile sensation.

In the above, amplitude data is generated on the main body 11 side using the data stored in the memory 550, the amplitude data is transmitted to the input device 100, and the input device 100 generates a drive signal using the amplitude data. Thus, the mode of driving the vibration element 140 has been described.

However, the vibration element 140 may be driven based on the movement direction and the movement amount detected by the movement detection unit 220 by the input device 100. In this case, the main body 11 does not have to be involved in the drive control of the vibration element 140. For example, when the input device 100 moves in a specific movement direction, the vibration element 140 may be driven in a predetermined pattern, or when the input device 100 moves by a specific movement amount, the vibration element 140 may be driven in a predetermined pattern. It may be driven by.

Here, a first modification of the embodiment will be described with reference to FIGS. 21 and 22.

FIG. 21 is a diagram illustrating a configuration of an input device 100A according to a first modification of the embodiment.

The input device 100A includes a control device 200A instead of the control device 200 of the input device 100 shown in FIG. The control device 200A is obtained by adding a memory 250 to the control device 200 shown in FIG.

The input device 100A of the first modified example stores data similar to the table format data shown in FIGS. 10, 14, and 19 in the memory 250, and generates amplitude data on the input device 100A side. Is.

Here, FIG. 8 is used for explanation. In the first modification, an identifier is assigned to a word for which a hyperlink is set. As such an identifier, for example, an identifier assigned by the OS can be used.

FIG. 22 is a diagram showing data stored in the memory 250.

The data stored in the memory 250 is data in which data representing the type of application, link ID, and pattern data representing a vibration pattern are associated with each other. The link ID is an identifier assigned to a word for which a hyperlink is set. The link ID is output by the control unit 510 as an example of an identifier output unit.

The amplitude data output unit 540 of the main body unit 11 transmits the link ID of the hyperlink touched by the pointer 12A to the input device 100A, and the drive control unit 240 refers to the data (FIG. 22) stored in the memory 250, and the application ID The vibration pattern corresponding to the link ID is read out. Then, the amplitude data included in the vibration pattern is output to the amplitude modulator 320. As a result, the vibration element 140 is driven by the drive signal output from the amplitude modulator 320.

In this way, table format data including vibration patterns may be stored in the memory 250 of the input device 100A.

Since the driving method of the vibration element 140 is the same as the first operation example described above, according to the first modification, it is possible to provide the input device 100A that can provide a good tactile sensation.

Also, a second modification of the embodiment described below may be used.

FIG. 23 is a diagram showing a main body 11A of a second modification of the embodiment. The main body 11A has a configuration in which the amplitude data output unit 540 is removed from the main body 11 shown in FIG. The main body 11A is used in combination with the input device 100A of the first modification.

In the second modification, the main body 11A transmits the hyperlink contact signal and the coordinates of the pointer 12A to the input device 100A. Then, the input device 100A drives the vibration element 140 by executing the process shown in FIG. 11 based on the hyperlink contact signal. Further, the input device 100A executes the process shown in FIG. 15 using the coordinates of the pointer 12A. Also, the input device 100A executes the process shown in FIG. 20 using the coordinates of the pointer 12A.

Since the driving method of the vibration element 140 is the same as that of the first modification described above, according to the second modification, it is possible to provide the input device 100A that can provide a good tactile sensation.
