Description

  The present disclosure relates to an electronic device that generates vibration in response to a touch operation by a user.

  An electronic device in which a touch panel is arranged on a display screen has been put into practical use. However, it is difficult for a user to feel an input operation feeling by touch panel operation, and an unintended touch input may be performed. Further, when the display screen is touched and operated, the display screen may be hidden by the touched finger, so that it may be difficult to confirm the display information.

  In order to improve the operability of touch input, a technique for giving a tactile sensation to a user by vibrating a touch panel is known. By applying a voltage to the piezoelectric element fixed to the touch panel, vibration is generated in the touch panel and a tactile sensation is given to the user (for example, see Patent Document 1).

  Patent Document 2 discloses an apparatus that scrolls and selects a menu displayed on the screen by providing a sensor unit outside the display screen and moving a finger touching the sensor unit up and down. Thereby, it is possible to prevent the display menu from being hidden by the touched finger.

(Embodiment 1)
In the electronic device disclosed in Patent Document 1, the touch operation is limited to the display screen. In the electronic device disclosed in Patent Document 2, a touch operation on the outside of the display screen is possible, but the touch operation is an operation performed only on the outside of the display screen, regardless of the touch operation on the display screen. It is an independent operation. In addition, in the electronic device disclosed in Patent Document 2, vibration corresponding to the touch operation does not occur. Therefore, in the conventional electronic device, vibration is not presented to the user when the touch position moves between the inside and the outside of the display screen.

  The electronic device according to the embodiment of the present disclosure presents the user with a tactile sensation due to vibration when the touch position moves between the inside and the outside of the display screen. Hereinafter, embodiments will be described with reference to the drawings.

<Overall configuration of electronic equipment>
The overall configuration of the electronic apparatus 10 according to the present embodiment will be described with reference to FIGS. 1, 2, 3, 4, 5, and 6.

  FIG. 1 is a perspective view showing an external appearance of the electronic device 10. FIG. 2 is a component development view of the electronic device 10. FIG. 3 is a cross-sectional view of the electronic device 10, and FIG. 4 is a front view of the electronic device 10. FIG. 5 is an external perspective view of the vibrating portion 13. FIG. 6 is a block diagram showing a configuration of the electronic device 10.

  As shown in FIGS. 1 and 2, the electronic device 10 includes a touch panel 11, a touch panel electrode 14, a vibrating portion 13 (13 a, 13 b), a spacer 17, a display panel 18, a fixture 16, a substrate 19, and a lower cover 15. . The touch panel 11 is disposed so as to cover the display surface side of the display panel 18.

  As shown in FIG. 3, the touch panel electrode 14 is attached to the touch panel 11. The touch panel electrode 14 is made of a transparent conductive material such as ITO (Indium Tin Oxide). The touch panel 11 detects a touch position by detecting a change in capacitance of the touch panel electrode 14 due to a user's touch operation. A vibrating portion 13 (13a, 13b) is attached to the lower side of the touch panel 11. The vibration unit 13 (13a, 13b) vibrates the touch panel 11. The display panel 18 and the substrate 19 are held by a fixing bracket 16, and the fixing bracket 16 is attached to the lower cover 15 with screws or the like. The touch panel 11 is attached to the lower cover 15 via a spacer 17. The spacer 17 is a buffer member such as silicon rubber or urethane rubber. The spacer 17 is fixed to the touch panel 11 and the lower cover 15 using an adhesive or a double-sided tape.

  As shown in FIG. 4, the display area 12 is an area where the video information displayed on the display panel 18 is visible. The operable area (touch position detectable area) 40 of the touch panel 11 is an area where a touch operation is possible. Since the area of the operable region 40 is wider than the display area 12, it is possible to detect the user touching the touch panel 11 in a wider range than the display area 12.

  As shown in FIG. 5, the vibration unit 13 includes a piezoelectric element 21, a shim plate 22, and a base 23. Piezoelectric elements 21 are attached to the front and back of the shim plate 22, and both ends of the shim plate 22 are attached to the base 23. The base 23 is affixed to the touch panel 11.

  The piezoelectric element 21 is formed of a piezoelectric ceramic such as lead zirconate titanate or a piezoelectric single crystal such as lithium niobate. The piezoelectric element 21 expands and contracts by applying a voltage. When one of the piezoelectric elements 21 attached to both sides of the shim plate 22 is expanded and the other is contracted, the shim plate 22 generates a flexural vibration. The frequency of vibration is, for example, about 100 to 400 Hz.

  The shim plate 22 is a spring member such as phosphor bronze. The vibration of the shim plate 22 vibrates the touch panel 11 through the base 23, and the user operating the touch panel 11 can sense the vibration of the touch panel 11. The base 23 is made of a metal such as aluminum or brass, or a plastic such as PET or PP.

  In this embodiment, the piezoelectric element 21 is attached to the shim plate 22, but the piezoelectric element 21 may be attached directly to the touch panel 11. Further, the piezoelectric element 21 may be directly attached to any member constituting the electronic device 10 such as the display panel 18 and the lower cover 15. Further, a thin transparent piezoelectric member may be formed on the touch panel 11 by a method such as sputtering, and used as the vibrating portion 13. In addition, when there is a cover member or the like on the touch panel 11, the piezoelectric element 21 may be attached to the cover member. In addition, when there exists a cover member on the touch panel 11, it is called the panel member which detects a touch position including both the touch panel 11 and a cover member. A vibration motor may be used as the vibration unit 13.

  As illustrated in FIG. 6, the electronic device 10 includes a display control unit 32 that controls display on the display panel 18, a touch panel control unit 31 that controls the touch panel 11, and a vibration control unit 33 that controls vibration of the vibration unit 13. The electronic device 10 also includes a microcomputer 20 that performs various controls and determinations, and various input / output units 37.

<Description of individual configuration>
The display panel 18 displays characters, numbers, icons, keyboards, and the like for receiving input from the user. When the keyboard is displayed on the display panel 18, the user can perform character input or the like by touching an arbitrary position on the keyboard. As the display panel 18, for example, a known display device such as a liquid crystal method, an organic EL method, an electronic paper method, or a plasma method can be used.

  The display control unit 32 controls the display content on the display panel 18 based on a control signal generated by the microcomputer 20.

  The touch panel 11 can detect a user's touch position. Information on the touch position of the user is sent to the microcomputer 20 via the touch panel control unit 31. As the touch panel 11, for example, a touch panel of an electrostatic type, a resistance film type, an optical type, an ultrasonic type, an electromagnetic type, or the like can be used.

  In this example, the touch panel 11 and the display panel 18 are separate components, but the touch panel 11 and the display panel 18 may be integrally formed. For example, a method such as an in-cell type touch panel that integrates a touch panel function inside a liquid crystal panel or an on-cell type touch panel that integrates a touch panel function on the surface of the liquid crystal panel may be used. Also in this case, the panel is formed so that the area of the operable region 40 is wider than the display area 12.

  The vibration unit 13 vibrates the touch panel 11. The vibration control unit 33 controls the vibration pattern of the vibration unit 13.

  FIG. 7 is a schematic diagram illustrating an example of a vibration pattern. In response to a command from the microcomputer 20, the vibration control unit 33 applies a voltage having a waveform as shown in FIG. 7 to the vibration unit 13 to vibrate the touch panel 11, thereby giving the user vibration A <b> 1. The voltage for applying the vibration A1 is a sine wave, for example, 150 Hz, 33 Vrms, and two cycles. The amplitude on the touch panel 11 at this time is about 5 μm. If the frequency and voltage are set so that the vibration amplitude on the touch panel 11 is about 5 to 50 μm, a comfortable touch (vibration) can be presented to a human finger.

  Next, a touch operation example will be described. In the electronic device 10 according to the embodiment, when the microcomputer 20 detects that the touched position has moved between the inside and the outside of the display area 12 while the user continues to touch the touch panel 11, The vibration control unit 33 changes the vibration. Further, the display control unit 32 changes the display content of the display panel 18 when the touch position moves between the inside and the outside of the display area 12. By changing the vibration of the touch panel 11 in accordance with the movement of the touch position between the inside and outside of the display area 12, it is possible to provide the user with a realistic operational feeling corresponding to the operation. As a method of changing the vibration of the touch panel 11, it may be changed between a state where there is no vibration and a state where there is vibration, or may be changed from one vibration to another. For example, the amplitude and / or frequency may be changed from a certain vibration state, or the period for generating the vibration may be changed.

<Touch operation example 1>
The operation of the touch operation example 1 will be described with reference to FIGS. 8A to 9. 8A to 8C are diagrams illustrating an operation state of the touch operation example 1. FIG. FIG. 9 is a time chart of the touch operation example 1, and shows the relationship between the touch input time and the touch position moving distance, and the drive timing of the vibration unit 13, the display information 50a, and the display information 50c.

  FIG. 8A shows a state in which display information 50a and 50b are displayed in the display area 12, and the user touches the display information 50a with a finger. FIG. 8B shows a state in which the user slides the display information 50a with the finger in the direction of the arrow 100a from the inside of the display area 12 toward the inner and outer boundaries 12a of the display area 12. At this time, the display information 50a and 50b move in the direction of the arrow 100a in accordance with the slide of the finger, and the display information 50c is newly displayed while moving in the direction of the arrow 100a. FIG. 8C shows a state in which the movement of the display information 50a, 50b, and 50c is completed, the display information 50b and 50c is displayed in the display area 12, and the user releases the finger.

  In FIG. 9, the operation timing chart 200 of the touch input time indicates ON when the user touches the touch panel 11 and OFF when the user does not touch. As shown in FIG. 8A, the operation timing chart 201 of the touch position movement distance has a place where the user first touched the touch panel 11 as a base point (0), a distance moved in the direction of the arrow 100a as X, and a display area 12 The position where the user's finger has reached the boundary 12a is indicated as X0. The operation timing chart 202 of the vibration unit 13 shows whether the vibration unit 13 vibrates and the touch panel 11 vibrates. The operation timing chart 203 of the display information 50a indicates the rate at which the display information 50a is displayed. The state shown in FIG. 8A is 100%, and the state shown in FIG. 8C is 0%. The operation timing chart 204 of the display information 50c shows the ratio at which the display information 50c is displayed. The state shown in FIG. 8A is 0%, and the state shown in FIG. 8C is 100%.

  8A to 8C, the touch operation in the present embodiment performs the following operation when the user touches the touch panel 11 with a finger.

  At time 210, the user touches the touch panel 11. Until time 211, when the user moves his / her finger in the direction of the arrow 100a at a substantially constant speed, the display area of the display information 50a is reduced with respect to the display area 12, and conversely, the display area of the display information 50c is Increase. The state at time 211 is the state shown in FIG. 8B.

  Here, when the user continuously moves his / her finger in the direction of the arrow 100a and exceeds the boundary 12a of the display area 12, the vibration unit 13 generates a pulse-like vibration as shown in FIG. Through 11, vibration is transmitted to the user's finger. Since the operable area 40 of the touch panel 11 is wider than the display area 12, a touch operation outside the display area 12 can also be detected. Moreover, the continuous movement of the touch position between the inside and the outside of the display area 12 can also be detected. At time 211, page display of the display information 50a, 50b, 50c is automatically executed. At time 212, as shown in FIG. 8C, the user's finger leaves the touch panel 11, and the display information 50b and 50c are automatically displayed on the entire screen.

  By vibrating the touch panel 11 in the operation as described above, the user can clearly confirm the page feed of the display information.

<Touch operation example 2>
The operation of the touch operation example 1 will be described with reference to FIGS. 10A to 11. 10A to 10C are diagrams illustrating an operation state of the touch operation example 2. FIG. 11 is a time chart of the touch operation example 2, and shows the relationship between the touch input time and the touch position moving distance, and the driving timing of the vibration unit 13 and the display information 50d. The display control unit 32 moves the display position of the information 50d according to the movement of the touch position. The display position of the information 50d is changed before and after the touch position crosses the inner and outer boundaries 12a of the display area 12. Change the direction of movement.

  FIG. 10A shows a state in which the display information 50d is displayed in the display area 12, and the user touches the display information 50d with a finger. FIG. 10B shows a state in which the user slides the display information 50d with the finger in the direction of the arrow 100b from the inside of the display area 12 toward the boundary 12a of the display area 12. At this time, the display information 50d moves in the direction of the arrow 100b in accordance with the slide of the finger. Since there is no new display information in the left direction of the display information 50d and it is in the so-called page last state, the display information 50d does not move to the right direction of the display area 12 and disappear. FIG. 10C shows a state in which the display information 50d moves in the direction opposite to the arrow 100b and returns to the center of the display area 12.

  In FIG. 11, the operation timing chart 300 of the touch input time indicates ON when the user touches the touch panel 11 and OFF when the user does not touch. As shown in FIG. 10A, the operation timing chart 301 of the touch position movement distance has a display area 12 as a distance moved in the direction of the arrow 100b, where X is a position where the user first touched the touch panel 11 as a base point (0). The position where the user's finger has reached the boundary 12a is indicated as X0. The operation timing chart 302 of the vibration unit 13 shows whether the vibration unit 13 vibrates and the touch panel 11 vibrates. The operation timing chart 303 of the display information 50d shows the ratio of the display information 50d being displayed, and the state shown in FIG. 10A is 100%.

  10A to 10C, the touch operation in the present embodiment performs the following operation when the user touches touch panel 11 with a finger.

  At time 310, the user touches the touch panel 11. Until time 311, when the user moves his / her finger in the direction of the arrow 100 b at a substantially constant speed, the display area of the display information 50 d is reduced with respect to the display area 12. The state at time 311 is the state shown in FIG. 10B. Here, when the user continuously moves his / her finger in the direction of the arrow 100b and exceeds the boundary 12a of the display area 12, the vibration unit 13 generates a pulse-like vibration as shown in FIG. Through 11, vibration is transmitted to the user's finger. At time 311, the movement of the display information 50 d is automatically canceled and moved to the center of the display area 12. At time 312, as shown in FIG. 10C, the display information 50 d is displayed on the entire display area 12.

  By vibrating the touch panel 11 in the operation as described above, the user can clearly confirm that the page of display information is the last page.

<Touch operation example 3>
The operation of the touch operation example 3 will be described with reference to FIGS. 12A to 13B. 12A to 12C are diagrams illustrating operation states of the touch operation example 3. FIG. 13A and 13B are diagrams illustrating vibration patterns of the vibration unit 13 in the touch operation example 3. FIG. The vibration control unit 33 varies the vibration amplitude of the vibration unit 13 according to the moving speed of the touch position when the touch position reaches the inner and outer boundaries 12 a of the display area 12. For example, the vibration amplitude when the moving speed is higher than when the moving speed is low is increased.

  FIG. 12A shows a state in which the display information 50e is displayed in the display area 12, and the user touches the outside of the display area 12 with a finger. FIG. 12B shows a state in which the user slides with the finger in the direction of the arrow 100c at the speed V1. The display information 50e moves by being flipped in the direction of the arrow 100c. FIG. 12C shows a state in which the user slides with the finger in the direction of the arrow 100c at the speed V2 from the state of FIG. 12A. The display information 50e moves by being flipped in the direction of the arrow 100c. The speed V1 and the speed V2 are in a relationship of V1 <V2, and the display information 50e moves faster in FIG. 12C than in FIG. 12B. 12B and 12C, when the finger exceeds the boundary 12a of the display area 12, the vibration unit 13 vibrates, so that the vibration is transmitted to the user's finger. FIG. 13A shows a vibration pattern when the speed is V1, and FIG. 13B shows a vibration pattern when the speed is V2. As shown in FIGS. 13A and 13B, the amplitude A of vibration is larger at the speed V2 than at the speed V1. The user feels a stronger vibration at the speed V2 than at the speed V1.

  By vibrating the touch panel 11 in the operation as described above, when the user performs an operation of flipping the display information 50e quickly, the user can obtain a realistic operational feeling by feeling a strong tactile sensation accordingly.

  Even if the finger sliding speed is the same, the strength of vibration may be changed according to the content of the display information 50e. For example, if the display information 50e is large, heavy, and rugged information such as “rock”, the vibration can be increased, and if the display information 50e is light and small information such as “pebbles”, the vibration can be reduced. You can get a good feeling of operation.

  In addition, although the method of changing the amplitude A in order to change the strength of vibration was shown, it is not limited to that method, and various vibration patterns such as vibration frequency and vibration time may be used.
