Description

  The present invention relates to an input device, a display device, an input device control method, and a program.

  2. Description of the Related Art Conventionally, there has been known a device that places an input device away from a display device such as a liquid crystal display, such as a touch pad. In such a device, operation switches are arranged around the touchpad (see, for example, Patent Document 1).

JP 2013-159273 A

  However, the conventional apparatus only has an operation switch arranged around the touch pad, and the design is not considered at all. Further, when performing an operation in which the touch pad and the operation switch come and go, it is necessary to visually confirm the position of the operation switch at that time. For example, a blind operation without looking at the hand cannot always be performed smoothly. Thus, the conventional apparatus cannot be said to have a high degree of freedom in operability and design.

  The present invention has been made in view of the above, and an object thereof is to provide an input device, a display device, an input device control method, and a program capable of improving the operability and the degree of freedom in design. .

  In order to solve the above-described problems and achieve the object, an input device of the present invention includes detection means, switch means, at least one vibration element, and vibration control means. The detecting means detects a contact position of the user with respect to the operation surface. The switch means detects the user's pressing operation with respect to a pressing surface that is disposed adjacent to the operating surface on a surface having continuity with the operating surface. The vibration element vibrates the operation surface. Based on the detection result of the detection means, the first vibration state occurs when the contact position moves on the operation surface, and the contact position moves between the operation surface and the pressing surface. The vibration element is controlled so as to be in a second vibration state different from the first vibration state.

  According to the present invention, the degree of freedom in design is improved by arranging the operation surface of the operation unit such as a touch pad and the pressing surface of the switch on the surface having continuity, and also has continuity. By transferring the movement between the operation surface and the pressing surface on the surface by vibration, it is possible to improve the operability such that the operation surface and the pressing surface can be moved by, for example, a blind operation without looking at the hand. An input device, a display device, an input device control method, and a program can be provided.

<1. Control method of input device>
FIG. 1 is a diagram for explaining a control method of the input device 10 according to the embodiment of the present invention. In the present embodiment, for example, a case will be described in which the in-vehicle display device 1 mounted on a car navigation system includes the input device 10.

  First, the outline | summary of the display apparatus 1 which concerns on this embodiment is demonstrated using FIG. Here, it is assumed that the display device 1 includes the input device 10 such as a touch panel.

  As shown in FIG. 1, the display device 1 according to this embodiment includes an input device 10 and a display unit 20. The display unit 20 is, for example, a liquid crystal display, and displays an image to the user in accordance with an input operation received by the input device 10. The display unit 20 displays an image such as an image for performing vehicle navigation such as a map, an image such as a television, a moving image on the Internet, or a still image.

  The input device 10 is arranged at a location different from the display unit 20. The input device 10 receives an input operation from a user. The input device 10 includes an operation unit 110, a vibration element 130 that vibrates the operation surface 120A of the operation unit 110, and first to third switch elements 140a to 140c.

  The operation unit 110 is, for example, a flat pad having a capacitive information input function. The operation unit 110 includes an operation surface 120A. When the user contacts the operation surface 120A with a pointing device such as a finger U1 or a touch pen, the input device 10 detects the contact position C of the user via the operation surface 120A.

  The vibration element 130 is, for example, a piezoelectric element, and vibrates the operation surface 120A of the operation unit 110 at a high frequency (for example, an ultrasonic frequency band). For example, when the vibration element 130 is vibrated while the user's finger U1 is in contact with the operation surface 120A, the state of the air layer between the finger U1 and the operation surface 120A changes, and the frictional force changes. When the finger U1 is moved in such a state, a tactile sensation according to the changed frictional force can be given to the finger U1. Also, by changing the vibration state of the vibration element 130, the magnitude of the frictional force between the finger U1 and the operation surface 120A can be changed, and the tactile sensation applied to the finger U1 can be changed.

  The first to third switch elements 140a to 140c (hereinafter also referred to as switches 140) have pressing surfaces 150a to 150c, respectively, and accept a user's pressing operation on the pressing surfaces 150a to 150c. The pressing surfaces 150a to 150c (hereinafter also referred to as the pressing surface 150) are arranged adjacent to the operation surface 120A so as to be flush with the operation surface 120A. Here, although the pressing surfaces 150a to 150c and the operation surface 120A are arranged on the same plane, the present invention is not limited to this. The pressing surfaces 150a to 150c may be arranged on a surface having smooth continuity with the operation surface 120A or on a surface without a discontinuous portion. For example, the pressing surfaces 150a to 150c are on the same curved surface as the operation surface 120A. You may arrange so that.

  As described above, the input device 10 according to the present embodiment accepts an input operation through the operation unit 110 and the switch 140 and vibrates the operation surface 120 </ b> A using the vibration element 130 to give a tactile sensation to the user. Hereinafter, a method for controlling the input device 10 will be described.

  The input device 10 detects the contact position C of the user with respect to the operation surface 120A. The input device 10 controls the vibration element 130 according to the detected contact position C. For example, when the contact position C is moving on the operation surface 120A as indicated by an arrow TB1 in FIG. 1, the input device 10 controls the vibration element 130 so as to be in the first vibration state.

  Further, for example, when the contact position C moves between the operation surface 120A and the pressing surface 150, as shown by an arrow TB2 in FIG. 1, the input device 10 causes the vibration element to be in the second vibration state. 130 is controlled.

  Here, the vibration state of the vibration element 130 being the first vibration state refers to a state where the vibration element 130 is vibrating at a high frequency, for example. When the vibration element 130 vibrates at a high frequency, the frictional force between the operation surface 120A and the contact surface (for example, the finger U1) with the user is reduced, and the user's finger U1 is easily slipped on the operation surface 120A. That is, the input device 10 can give the user's finger U1 a smooth tactile sensation, for example, by making the vibration state of the vibration element 130 the first vibration state.

  Further, the vibration state of the vibration element 130 being the second vibration state refers to a state where the vibration element 130 is not vibrating, for example. When the vibration element 130 is not vibrating, a predetermined frictional force is generated between the operation surface 120A and the contact surface (for example, the finger U1) between the user and the user's finger U1 is compared with the first vibration state. It becomes difficult to slide on 120A. That is, the input device 10 can give a tactile sensation that is difficult to slip, for example, to the user's finger U1 by setting the vibration state of the vibration element 130 to the second vibration state.

  Here, it is assumed that the user's finger U1 moves from the operation surface 120A to the pressing surface 150 by moving in the order of the arrow TB1 and the arrow TB2. In this case, the input device 10 gives a smooth tactile sensation to the finger U1 by controlling the vibration element 130 in the first vibration state, for example, on the operation surface 120A where the contact position C is along the arrow TB1, and vibrates with the arrow TB2. By controlling the element 130 to the second vibration state, a great sense of resistance is given to the finger U1.

  At this time, when the user moves from the operation surface 120 </ b> A to the pressing surface 150, for example, the user feels a great resistance feeling over a step. Thereby, the input device 10 can make the user recognize the boundary between the operation surface 120 </ b> A and the pressing surface 150.

  Thus, in the control method of the input device 10 according to the present embodiment, when the contact position C moves on the operation surface 120A, the vibration state of the vibration element 130 is set to the first vibration state so that the user's finger U1 is moved. When a smooth tactile sensation is given to move between the operation surface 120A and the pressing surface 150, a tactile sensation that is difficult to slip is given by setting the vibration state to the second vibration state.

  Thereby, even when there is no physical boundary between the operation surface 120A and the pressing surface 150 of the input device 10, the user can recognize the boundary between the operation surface 120A and the pressing surface 150. . Therefore, for example, the operation unit 110 and the switch 140 of the input device 10 can be integrally formed, and the degree of freedom in design of the input device 10 can be improved.

  Further, emphasizing the design of the input device 10, for example, even when a physical boundary is not provided between the operation surface 120 </ b> A and the pressing surface 150, the boundary between the operation surface 120 </ b> A and the pressing surface 150 is indicated to the user. It can be recognized, and the convenience of the user's input operation can be improved.

  From the viewpoint of the design of the input device 10, for example, the operation unit 110 such as a touch pad and the surfaces (the operation surface 120A and the pressing surface 150) of the switch unit 140 disposed around the operation unit 110 are continuous surfaces (for example, flat surfaces). Or a curved surface) is known as one typical design. In the case of such a design, for example, for a blind operation in which the operation is performed without visually checking the hand, it is difficult to identify the region of each operation part (the operation unit 110 and the switch unit 140), and the operability is somewhat difficult. There is.

  Therefore, in the input device 10 according to the present embodiment, the operation unit 110 such as a touch pad and the switch unit 140 are arranged on the same plane, thereby improving the degree of freedom in design and the operation unit on the same plane. By transmitting the movement between 110 and the switch unit 140 by vibration, the operation unit 110 and the switch unit 140 can be moved back and forth by, for example, a blind operation without looking at the hand, thereby improving the operability with respect to the input device 10. Can be made.

  For example, when the display device 1 including the input device 10 is mounted on a vehicle, a driver who is a user needs to pay attention to the surrounding situation, and may not be able to perform an input operation while watching the input device 10. There is. Even in such a case, the user can easily operate the input device 10 by changing the vibration state of the vibration element 130 to allow the user to recognize the boundary between the operation surface 120A and the pressing surface 150. .

  Although the case where the display device 1 is a display device of a navigation system mounted on a vehicle has been described here, the present invention is not limited to this. For example, the display device 1 may be a personal computer having a touch pad or a pen tablet. Hereinafter, the display device 1 including the input device 10 controlled by the control method will be further described.

<2. Outline of Display Device 1>
FIG. 2 is a diagram showing an overview of the display device 1 according to the present embodiment. The display device 1 is mounted in a vehicle as shown in FIG. The display device 1 includes a display unit 20 and an input device 10. The display unit 20 of the display device 1 is disposed, for example, at a position that is easily visible from the driver in the driver's seat in the vehicle.

  The input device 10 is disposed at a position where it can be easily operated by the driver, for example, near the shift lever of the center console. In the example of FIG. 2, the palm rest P is disposed around the input device 10. By providing the palm rest P around the input device 10, fatigue due to the input operation of the user (driver) can be reduced.

  Further, for example, a switch (not shown) may be provided on the palm rest P, and the user may operate the switch by pushing the palm rest P with a palm. The input operation accepted by the switch includes a determination operation for determining the operation selected by the input device 10. As described above, the input device 10 may include the palm rest P as means for receiving an input operation.

  The display unit 20 is arranged at a position where it can be easily seen by a user who is a driver, and the input device 10 is arranged at a position away from the display unit 20 so that the driver can easily operate. Can be easily performed.

<3. Details of Display Device 1>
Next, details of the display device 1 will be described with reference to FIG. FIG. 3 is a block diagram illustrating a configuration of the display device 1 according to the present embodiment. The display device 1 includes an input device 10, a display unit 20, a display control unit 30, and a storage unit 40.

<3.1. Input device 10>
The input device 10 is an information input device such as a touch pad or a switch, for example. The input device 10 receives an input operation by the user on the display device 1 and outputs a signal corresponding to the user's input operation to the display control unit 30. The input device 10 includes an operation unit 110, a vibration element 130, a switch 140, and a control unit 160.

<3.1.1. Operation unit 110>
The operation unit 110 is a flat plate sensor such as a touch pad or a pen tablet. As shown in FIG. 4, the operation unit 110 is disposed in the housing 170 of the input device 10. The operation unit 110 includes an operation surface 120A that receives an input operation by a user. When the user touches operation surface 120 </ b> A, operation unit 110 outputs a sensor value corresponding to user contact position C to control unit 160.

<3.1.2. Vibration Element 130>
The vibration element 130 is a piezoelectric actuator such as a piezoelectric element (piezo element), for example, and vibrates the operation unit 110 by expanding and contracting according to a voltage signal given from the control unit 160. In the example of FIG. 4, the vibration element 130 is disposed on a surface facing the operation surface 120 </ b> A of the operation unit 110. FIG. 4 is a schematic diagram for explaining an arrangement example of the vibration element 130 and the switch 140, and illustration of components unnecessary for explanation is omitted. 4A is a top view of the input device 10, and FIG. 4B is a cross-sectional view of the input device 10 taken along line L1 in FIG. 4A.

  Note that the number and arrangement of the vibration elements 130 illustrated in FIG. 4 are merely examples, and the present invention is not limited thereto. For example, the operation surface 120A may be vibrated by one or more vibration elements. As described above, the number and arrangement of the vibration elements 130 are arbitrary, but it is desirable that the number and arrangement be such that the entire operation surface 120A is vibrated uniformly.

  Although the case where a piezoelectric element is used as the vibration element 130 has been described here, the present invention is not limited to this. For example, the vibration element 130 may be an element that vibrates the operation surface 120A in an ultrasonic frequency band.

<3.1.3. Switch 140>
The switch 140 has, for example, a pressing surface 150 and detects a user's pressing operation on the pressing surface 150. When the user presses down the pressing surface 150 of the switch 140, for example, a contact (not shown) comes into contact, and a signal flows through the switch 140. For example, the switch 140 outputs such a signal to the control unit 160. As illustrated in FIG. 4, the switch 140 is disposed in the casing 170 of the input device 10 so as to be adjacent to the operation unit 110.

  In the example of FIG. 4A, the switch 140 includes first to third switch elements 140a to 140c. Each switch element 140a-140c is arrange | positioned so that one side of corresponding pressing surface 150a-150c may contact | connect one side of the outer periphery of 120 A of operation surfaces. As shown in FIG. 4B, the switch elements 140a to 140c are arranged such that the pressing surfaces 150a to 150c are flush with the operation surface 120A.

  As shown in FIG. 4B, the first to third switch elements 140a to 140c have elastic bodies such as springs, for example, and the first to third switches are pushed by the user pushing the elastic bodies. Contacts (not shown) of the elements 140a to 140c come into contact with each other, and a signal flows. For example, when the user lifts his / her finger from the pressing surfaces 150a to 150c, the pressing surfaces 150a to 150c return to their original positions by the repulsive force of the elastic body. Thus, the first to third switch elements 140a to 140c are so-called mechanical switch means.

  Here, the first to third switch elements 140a to 140c are mechanical switch means, but are not limited thereto. The first to third switch elements 140a to 140c may be any switches that can detect a user's pressing operation, and are capacitive switches that can detect a pressing force perpendicular to the pressing surface 150, for example. Also good.

  Although FIG. 4 shows the case where the pressing surface 150 of the switch 140 and the operation surface 120A of the operation unit 110 are configured by different flat plates, the present invention is not limited to this. For example, the pressing surface 150 and the operation surface 120A may be formed of the same flat plate. Alternatively, the pressing surface 150 and the operation surface 120A may be integrally formed by covering them with a resin sheet, for example. In this way, the degree of freedom in design of the input device 10 can be improved.

  Further, for example, the pressing surface 150 and the operation surface 120 </ b> A may be configured by the same flat plate, and the pressing surface 150 may be vibrated using the vibration element 130. Alternatively, the pressing surface 150 may be vibrated by arranging a vibration element that vibrates the pressing surface 150. Thereby, the movement between the pressing surface 150 and the operation surface 120A on the same plane can be transmitted by vibration, and the movement between the pressing surface 150 and the operation surface 120A can be performed by, for example, a blind operation without looking at the hand, The operability with respect to the input device 10 can be improved.

  Note that the number and arrangement of the switch elements illustrated in FIG. 4 are examples, and are not limited thereto. For example, the two switch elements may be arranged so as to be in contact with different sides of the operation surface 120A. As described above, the number and arrangement of the switch elements are arbitrary, but it is desirable that the number and arrangement be such that, for example, the user can perform an input operation without viewing the input device 10.

<3.1.4. Control unit 160>
The control unit 160 controls each unit of the input device 10. In addition, the control unit 160 outputs a signal corresponding to the input operation received via the operation unit 110 or the switch 140 to the display control unit 30. The control unit 160 includes a detection unit 161, a movement determination unit 162, a switch detection unit (SW detection unit) 163, a press determination unit 164, and a vibration control unit 165.

<3.1.4.1. Detection unit 161>
Based on the sensor value output from the operation unit 110, the detection unit 161 detects the contact position C of the user with respect to the operation surface 120A. For example, the detection unit 161 detects the contact position C of the user at a predetermined cycle, so that even if the user's finger U1 moves on the operation surface 120A and the contact position C changes, the detection unit 161 starts. The contact position C can be detected following the change. The detection unit 161 outputs the contact position C of the user as a detection result to the movement determination unit 162.

<3.1.4.2. Movement determination unit 162>
The movement determination unit 162 determines whether the contact position C moves on the operation surface 120A or whether the contact position C moves between the operation surface 120A and the pressing surface 150 based on the detection result of the detection unit 161. . For example, the movement determination unit 162 determines that the contact position C moves between the operation surface 120A and the pressing surface 150 when the contact position C moves in the adjacent region D1 of the operation surface 120A. Further, when the contact position C moves in the movement region D2 excluding the adjacent region D1 of the operation surface 120A, it is determined that the contact position C moves on the operation surface 120A.

  Here, the determination method of the movement determination unit 162 will be described with reference to FIG. FIG. 5 is a schematic diagram illustrating details of the input device 10. First, the adjacent area D1 is an outer peripheral area of the operation surface 120A and is adjacent to the pressing surface 150. In the example shown in FIG. 5A, the adjacent region D1 is a rectangular region having a predetermined width W with a length adjacent to the switch elements 140a to 140c of the operation surface 120A.

  For example, as shown in FIG. 5A, when the contact position C1 of the user U1 is located in the movement area D2, the movement determination unit 162 determines that the contact position C is moved in the movement area D2, and the contact position C is operated. It determines with moving on the surface 120A.

  For example, when the contact position C2 of the user U2 is located in the adjacent area D1, the movement determination unit 162 assumes that the contact position C1 moves in the adjacent area D1, and the contact position C is between the pressing surface 150 and the operation surface 120A. Determine to move between. The movement determination unit 162 outputs the determination result to the vibration control unit 165 and the display control unit 30.

  In the above-described example, when the contact position C is located in the adjacent region D1, the movement determination unit 162 determines that the contact position C moves between the pressing surface 150 and the operation surface 120A. Not limited. For example, when the contact position C is located on the operation surface 120A, the operation surface 120A is moved, and when the contact position C is not located on the operation surface 120A, the contact position C is moved between the pressing surface 150 and the operation surface 120A. Then, it may be determined.

  Alternatively, when the contact position C detected in the adjacent area D1 is no longer detected on the operation surface 120A, or when the contact position C not detected on the operation surface 120A is detected in the adjacent area D1 It may be determined that C moves between the pressing surface 150 and the operation surface 120A.

<3.1.4.3. SW detection unit 163>
The SW detection unit 163 is a switch unit that detects a user's pressing operation on the pressing surface 150. The SW detection unit 163 detects the pressing operation by detecting a signal output by the switch 140 in response to the pressing operation by the user. The SW detection unit 163 outputs the detection result to the press determination unit 164.

<3.1.4.4. Press determination unit 164>
The press determination unit 164 determines whether any of the switch elements 140a to 140c of the switch 140 is pressed according to the detection result of the SW detection unit 163. Further, the pressing determination unit 164 determines whether the pressing operation has been completed, that is, whether the pressing surface 150 has returned to the original state, according to the detection result of the SW detection unit 163.

  As described above, the pressing determination unit 164 determines whether or not the switch 140 is pressed and determines the position of the pressing surface 150 of the switch 140. The pressing determination unit 164 outputs the determination result to the vibration control unit 165 and the display control unit 30.

<3.1.4.5. Vibration Control Unit 165>
The vibration control unit 165 enters the first vibration state when the contact position C moves on the operation surface 120A according to the determination result of the movement determination unit 162, and the contact position C becomes the operation surface 120A and the pressing surface 150. The vibration element 130 is controlled so as to be in the second vibration state when moving between the two.

  For example, as illustrated in FIG. 5A, when the contact position C1 is located in the movement region D2, the vibration control unit 165 enters the first vibration state in which the frictional force between the user and the operation surface 120A is reduced. Thus, the vibration element 130 is controlled. For example, when the contact position C2 is located in the adjacent region D1, the vibration control unit 165 controls the vibration element 130 so as to be in the second vibration state in which the frictional force between the user and the operation surface 120A is increased. .

  Here, a case where the finger U moves along the arrow TB3 in FIG. When the finger U moves along the arrow TB31, the contact position C is located in the movement area D2. Therefore, in this case, the vibration control unit 165 controls the vibration element 130 to be in the first vibration state. As a result, the input device 10 can give a predetermined resistance R1 to the finger U as shown in FIG. 5B, for example, and the user can easily move the finger U with a slippery tactile sensation.

  When the finger U moves along the arrow TB32, the contact position C is located in the adjacent region D1. Therefore, in this case, the vibration control unit 165 controls the vibration element 130 to be in the second vibration state. Thereby, the input device 10 can give the finger U a resistance R2 greater than the resistance R1 as shown in FIG. 5B, for example, and the user is less likely to move the finger U with a non-slip tactile sense.

  When the finger U moves along the arrow TB33, the finger U feels resistance according to the frictional force of the pressing surface 150b of the switch element 140b. For example, when the pressing surface 150 is made of the same material as the operation surface 120A of the operation unit 110, the input device 10 gives a resistance R2 to the finger U as shown in FIG. This makes it difficult to move the finger U.

  Thereby, when the finger U moves along the arrow TB3, when the finger U moves from the moving region D2 to the adjacent region D1, the resistance R increases greatly as shown in FIG. Therefore, for example, the input device 10 can give the finger U a tactile sensation as if over the step at the side where the moving region D2 and the adjacent region D1 are in contact, and recognizes the boundary between the operation surface 120A and the pressing surface 150 to the user. Can be made. For this reason, for example, by arranging the operation surface 120A and the pressing surface 150 to be in the same plane, even if it is difficult to understand the boundary between the operation surface 120A and the pressing surface 150, the user can easily recognize the boundary. be able to.

  The vibration control unit 165 controls the vibration element 130 according to the determination result of the pressing determination unit 164. For example, when the finger U is pressing the switch 140, the vibration control unit 165 performs control so that the vibration element 130 does not operate.

  Further, when the pressing operation is finished, the vibration control unit 165 controls the vibration element 130 to be in a predetermined vibration state. For example, the vibration control unit 165 controls the vibration element 130 to be in the second vibration state. Thereby, when the finger U moves from the pressing surface 150 of the switch 140 to the operation surface 120A, the vibration control unit 165 can give the finger U a resistance R2.

  Further, when the finger U moves from the adjacent region D1 to the moving region D2 on the operation surface 120A, the vibration control unit 165 controls the vibration element 130 so as to be in the first vibration state, so that the finger U is switched. Even when moving from the pressing surface 150 of 140 to the operation surface 120A, for example, a tactile sensation that steps down a step can be given to the finger U.

  When vibrating the pressing surface 150 using the vibration element 130, the vibration control unit 165 controls the vibration element 130 so that the frictional resistance between the pressing surface 150 and the finger U changes. For example, at the arrow TB33 in FIG. 5A, the vibration control unit 165 may control the vibration element 130 so as to be in the first vibration state, that is, to give a resistance R1 to the finger U.

  In this case, only when the input device 10 moves to the finger U along the arrow TB32, a large resistance R2 is given. For example, the finger U can be given a tactile sensation as if the finger U got over the convex portion.

  Further, when the finger U moves between the switch elements 140a to 140c, the vibration control unit 165 may control the vibration element 130 so that the frictional resistance between the pressing surface 150 and the finger U changes. .

  For example, an adjacent region is provided on adjacent sides of the switch elements 140a to 140c, and the vibration control unit 165 causes the vibration element 130 to vibrate in the second vibration state when the contact position C of the user is located in the adjacent region. To control. The vibration control unit 165 controls the vibration element 130 to vibrate in the first vibration state when the contact position C of the user is located on the pressing surface 150 excluding the adjacent region.

  Thereby, for example, when the contact position C of the user moves between the plurality of switch elements 140a to 140c, the user can recognize the boundary between the plurality of switch elements 140a to 140c by changing the tactile sensation of the adjacent region. .

  Further, the vibration control unit 165 may change the vibration state of the vibration element 130 according to the detection result of the SW detection unit 163. For example, when the press determination unit 164 determines that the switch 140 is pressed, the vibration control unit 165 controls the vibration element 130 so as to be in the first vibration state. For example, when the pressing determination unit 164 determines that the pressing operation of the switch 140 has ended, the vibration control unit 165 controls the vibration element 130 so as to be in the second vibration state.

  Thereby, for example, the input device 10 gives a tactile sensation as if the switch 140 was pressed with a larger stroke to the user who pressed the switch 140 or a tactile sensation as if the switch 140 was clicked. Thus, the user operability can be improved.

  Note that the method of notifying the boundary when moving between the operation surface 120A and the pressing surface 150 is not limited to the notification by the tactile sensation described above. For example, notification may be made by outputting a sound when moving between the operation surface 120A and the pressing surface 150. At this time, for example, sound may be output through a speaker (not shown), or the vibration control unit 165 causes the vibration element 130 to vibrate in the audible region, thereby changing the tactile sensation according to the change in vibration or audible operation. Sound may be output by vibration of frequency. Or you may make it transmit a vibration directly to a user by controlling the vibration element 130 so that the input device 10 itself may vibrate.

<3.2. Display unit 20>
The display unit 20 is a liquid crystal display, for example, and presents an image output from the display control unit 30 to the user. The display unit 20 is a so-called remote display disposed at a position away from the input device 10.

<3.3. Display Control Unit 30>
For example, the display control unit 30 generates an image to be displayed on the display unit 20 based on an input operation received by the input device 10 from the user. In addition, the display control unit 30 generates an image corresponding to the contact position C on the operation surface 120 </ b> A detected by the input device 10. The display control unit 30 outputs the generated image to the display unit 20. The display control unit 30 controls the display unit 20 to cause the user to present an image.

  The display control unit 30 generates an image corresponding to the determination result of the movement determination unit 162 of the input device 10 and causes the display unit 20 to display the image. For example, as shown in FIG. 6, when the user's finger U moves from the operation surface 120A to the pressing surface 150b along the arrow TB, the display control unit 30 generates an image G1 corresponding to the pressing operation accepted by the switch 140. To be displayed on the display unit 20. FIG. 6 is a diagram illustrating an example of the image G1 displayed on the display unit 20.

  In addition, the display control unit 30 changes the display color of the image G1 corresponding to the switch 140 according to the determination result of the pressing determination unit 164 of the input device 10 and causes the display unit 20 to display the display color. For example, the switch 140 being pressed is notified to the user by changing the display color of the image G1 corresponding to the switch 140 being pressed and causing the display unit 20 to display it. In this manner, the display control unit 30 displays the image G1 corresponding to the pressing operation of the switch 140 detected by the SW detection unit 163 on the display unit 20.

  Moreover, you may make it the press determination part 164 determine which switch element 140a-140c the user is contacting, for example. In this case, the display control unit 30 changes the display color of the image G1 corresponding to the switch 140 in contact with the user and causes the display unit 20 to display the image G1.

  Thus, the display control unit 30 displays the image G1 corresponding to the input device 10 on the display unit 20 in accordance with the user's contact operation. Thereby, it becomes easy for the user to perform an input operation while visually recognizing the display unit 20 instead of the input device 10.

  In addition, by changing the frictional force of the operation surface 120A of the input device 10, the user can recognize the position of the switch 140 of the input device 10 by touch, and the image G1 corresponding to the switch 140 is displayed on the display unit 20. The user recognizes the position of the switch 140 also visually. Thereby, the operativity with respect to a user's input operation can further be improved.

<3.4. Storage unit 40>
The storage unit 40 stores, for example, the adjacent region D1 and the movement region D2 that the movement determination unit 162 uses to determine the contact position C. In addition, the storage unit 40 stores determination results obtained by the movement determination unit 162 and the press determination unit 164. The storage unit 40 stores the image G1 generated by the display control unit 30. As described above, the storage unit 40 stores information and processing results necessary for processing performed by each unit of the display device 1.

  The storage unit 40 is a semiconductor memory device such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk.

<4. Control processing>
Next, a processing procedure executed by the input device 10 according to the present embodiment will be described with reference to FIG. FIG. 7 is a flowchart illustrating a processing procedure executed by the input device 10 according to the present embodiment.

  As illustrated in FIG. 7, the input device 10 determines whether or not the detection unit 161 has detected the contact position C of the user (Step S <b> 101). When the detection unit 161 does not detect the contact position C (step S101; No), the input device 10 ends the process.

  When the detection part 161 detects the contact position C (step S101; Yes), the input device 10 determines whether the contact position C is moving between the operation surface 120A and the pressing surface 150 (step S102). ).

  When the contact position C is moving between the operation surface 120A and the pressing surface 150 (step S102; Yes), the input device 10 controls the vibration element 130 to be in the second vibration state (step S103). ), The process is terminated.

  When the contact position C does not move between the operation surface 120A and the pressing surface 150, that is, when the contact position C moves on the operation surface 120A (step S102; No), the input device 10 includes the vibration element 130 in the first position. 1 is controlled (step S104), and the process is terminated.

<5. Hardware configuration>
The display device 1 according to the present embodiment can be realized by a computer 600 having a configuration illustrated as an example in FIG. FIG. 8 is a hardware configuration diagram illustrating an example of a computer that implements the functions of the display device 1.

  The computer 600 includes a CPU (Central Processing Unit) 610, a ROM (Read Only Memory) 620, a RAM (Random Access Memory) 630, and an HDD (Hard Disk Drive) 640. The computer 600 also includes a media interface (I / F) 650, a communication interface (I / F) 660, and an input / output interface (I / F) 670.

  The computer 600 may include an SSD (Solid State Drive), and the SSD may execute a part or all of the functions of the HDD 640. Further, an SSD may be provided instead of the HDD 640.

  The CPU 610 operates based on a program stored in at least one of the ROM 620 and the HDD 640 and controls each unit. The ROM 620 stores a boot program executed by the CPU 610 when the computer 600 starts up, a program depending on the hardware of the computer 600, and the like. The HDD 640 stores a program executed by the CPU 610, data used by the program, and the like.

  The media I / F 650 reads programs and data stored in the storage medium 680 and provides them to the CPU 610 via the RAM 630. The CPU 610 loads such a program from the storage medium 680 onto the RAM 630 via the media I / F 650, and executes the loaded program. Alternatively, the CPU 610 executes a program using such data. The storage medium 680 is, for example, a magneto-optical recording medium such as a DVD (Digital Versatile Disc), an SD card, or a USB memory.

  The communication I / F 660 receives data from other devices via the network 690 and sends the data to the CPU 610, and transmits the data generated by the CPU 610 to other devices via the network 690. Alternatively, the communication I / F 660 receives a program from another device via the network 690, sends the program to the CPU 610, and the CPU 610 executes the program.

  The CPU 610 controls a display unit 20 such as a display, an output unit such as a speaker, and input units such as a keyboard, a mouse, a button, and an operation unit 110 via an input / output I / F 670. The CPU 610 acquires data from the input unit via the input / output I / F 670. In addition, the CPU 610 outputs the generated data to the display unit 20 and the output unit via the input / output I / F 670.

  For example, when the computer 600 functions as the display device 1, the CPU 610 of the computer 600 executes a program loaded on the RAM 630, thereby pressing the detection unit 161, the movement determination unit 162, and the SW detection unit 163. Each function of the control unit 160 and the display control unit 30 of the input device 10 including the determination unit 164 and the vibration control unit 165 is realized.

  For example, the CPU 610 of the computer 600 reads these programs from the storage medium 680 and executes them, but as another example, these programs may be acquired from other devices via the network 690. Further, the HDD 640 can store information stored in the storage unit 40.

<6. Modification>
In the following, various modifications of the embodiment will be given with respect to how to give a tactile sensation in the input device 10 that gives a tactile sensation to the user by vibrating the operation surface. By using these tactile sensation imparting techniques, including the techniques described above, in combination as appropriate, it becomes possible to give tactile sensations having a wide variety of effects to the user.

  The modification of this embodiment is demonstrated using FIGS. 9-13. FIG. 9 is a block diagram showing a configuration of the display device 2 according to this modification. The input device 11 of the display device 2 according to this modification includes a second display unit 190 and a control unit 260 in addition to the configuration of the input device 10 shown in FIG. The control unit 260 includes an area determination unit 166 and a second display control unit 167 in addition to the configuration of the control unit 160 shown in FIG. The same components as those of the display device 1 shown in FIG.

  The second display unit 190 is, for example, a liquid crystal display, and is disposed so as to be in contact with a surface facing the operation surface 120A of the operation unit 110 as illustrated in FIG. Here, the operation unit 110 is a transmissive panel having a capacitive information input function such as a touch panel. As illustrated in FIG. 10, the operation unit 110 of the input device 11 includes a step 200 having a predetermined height between the operation surface 120 </ b> A and the pressing surface 150. The step 200 is formed to be higher than the plane on which the operation surface 120A and the pressing surface 150 are formed. FIG. 10 is a schematic diagram showing the configuration of the input device 11 according to this modification. 10A is a top view of the input device 11, and FIG. 10B is a cross-sectional view of the input device 11 taken along line L1 in FIG. 10A.

  The second display unit 190 displays the image generated by the second display control unit 167. The user can view the image displayed in the display area of the second display unit 190 through the transmissive operation surface 120A. Here, it is assumed that the second display unit 190 is, for example, a display means having a lower resolution than the display unit 20 and simpler than the display unit 20.

  Or you may comprise the 2nd display part 190 by illumination, such as a some LED light, for example. In this case, the second display unit 190 turns on / off the LED light in accordance with an instruction from the second display control unit 167.

  The area determination unit 166 includes an area setting unit 168 that sets a divided area on the operation surface 120 </ b> A based on an image displayed on the display unit 20. When the area setting unit 168 receives information on the image to be displayed on the display unit 20 from the display control unit 30, the area setting unit 168 divides the operation surface 120A based on the information and sets divided areas.

  The divided areas will be described with reference to FIG. FIG. 11 is a diagram for explaining the divided regions D11 to D14. For example, as illustrated in FIG. 11, it is assumed that an image G10 indicating a map and images G11 to G14 corresponding to four operations received by the display device 2 are displayed on the display unit 20. In this case, the area setting unit 168 divides the operation surface 120A into four divided areas D11 to D14 corresponding to the images G11 to G14 along the boundary line L.

  Note that the divided regions D11 to D14 illustrated in FIG. 11 are examples, and the number and arrangement of the regions are not limited thereto. The divided areas D11 to D14 may be set so as to correspond to the image displayed on the display unit 20, and may be an arbitrary number and arrangement.

  Based on the detection result of the detection unit 161, the region determination unit 166 moves the contact position C in the first region (for example, the divided region D11) of the operation surface 120A or is adjacent to the first region of the operation surface 120A. It is determined whether to move the second area (for example, the divided area D12) or between the first and second areas. That is, the area determination unit 166 determines whether the contact position C moves within the plurality of divided areas D11 to D14 or between the plurality of divided areas D11 to D14.

  For example, as illustrated in FIG. 12, the region determination unit 166 sets a second adjacent region D3 including the boundary line L of the divided regions D11 to D14 set by the region setting unit 168. For example, as shown in FIG. 11, when four divided regions D11 to D14 of 2 rows and 2 columns are set on the operation surface 120A, the second adjacent region D3 is divided into four divided regions D11 as shown in FIG. A cross-shaped region D3 having a width W including D14. In addition, FIG. 12 is a figure explaining 2nd adjacent area | region D3.

  For example, when the contact position C of the user U is located in the movement areas D41 to D44 excluding the second adjacent area D3 based on the detection result by the detection unit 161, the area determination unit 166 determines that the contact position C is the movement areas D41 to D44. It is determined that the contact position C moves within the divided areas D11 to D14 of the operation surface 120A.

  For example, when the contact position C of the user U is located in the second adjacent area D3, the area determination unit 166 assumes that the contact position C moves in the second adjacent area D3, and the contact position C is divided into the divided areas D11 to D14. Determine to move between. The area determination unit 166 outputs the determination result to the vibration control unit 165 and the second display control unit 167. In addition, the region determination unit 166 outputs information regarding the divided regions D11 to D14 set by the region setting unit 168 to the second display control unit 167.

  Based on the determination result of the region determination unit 166, the vibration control unit 165 enters the first vibration state when the contact position C moves in the first or second region, and the contact position C is in the first and second states. When moving between these regions, the vibration element 130 is controlled so as to be in the second vibration state.

  For example, in the example illustrated in FIGS. 11 and 12, when the contact position C is located in the movement region D41 to D44, the vibration control unit 165 performs the first vibration in which the frictional force between the user and the operation surface 120A is reduced. The vibration element 130 is controlled so as to be in a state. For example, when the contact position C is located in the second adjacent region D3, the vibration control unit 165 causes the vibration element 130 to be in the second vibration state in which the frictional force between the user and the operation surface 120A is increased. Control.

  As a result, when the contact position C moves between the divided areas D11 to D14, for example, a tactile sensation as if over the step at the boundary between the divided areas D11 to D14 can be given to the finger U, and the divided areas D11 to D14 can be given to the user. The boundary of D14 can be recognized. For this reason, when the operation surface 120A is divided into a plurality of divided areas D11 to D14, the divided areas D11 to D14 can be recognized by the user with the antenna.

  In the example illustrated in FIG. 12, the adjacent region D1 provided at the boundary between the operation surface 120A and the pressing surface 150 is configured to be the same region as the step 200. Thereby, when the user's finger U exceeds the step 200, the frictional force between the user and the step 200 can be increased. For example, even when the height of the step 200 is low, the user can It becomes easy to recognize. Therefore, for example, even when the step 200 is provided between the operation surface 120A and the pressing surface 150, the height of the step 200 can be set low, and the degree of freedom in design of the input device 10 is improved. be able to. As described above, by arranging the operation surface 120A and the pressing surface 150 on the same plane, the degree of freedom in design is improved, and the movement between the operation surface 120A and the pressing surface 150 on the same plane is vibration. By telling the difference in level, the operation surface 120A and the pressing surface 150 can be moved back and forth by a blind operation without looking at the hand, for example, and the operability with respect to the input device 10 can be improved.

  The second display control unit 167 causes the second display unit 190 to display an image corresponding to the determination result of the region determination unit 166 and information regarding the divided regions D11 to D14. For example, the boundary line L of the divided areas D11 to D14 is displayed on the second display unit 190. Alternatively, by changing the background color of the divided area (for example, divided area D11) where the user's contact position C is located to a different color from the other divided areas (for example, divided areas D12 to D14), the operation surface 120A of the finger U is displayed to the user. You may make it notify the position in.

  In addition, the second display control unit 167 may display an image corresponding to the image displayed on the display unit 20 on the second display unit 190. For example, as shown in FIG. 11, when the image G13 including the characters “telephone” is displayed on the display unit 20, for example, a telephone icon is displayed in the corresponding divided area D13.

  Thus, by displaying a simple image corresponding to the image displayed on the display unit 20 on the second display unit 190, the user can perform an input operation while viewing the input device 11, and the user's operation Convenience can be improved.

  In the input device 11 described above, for example, as illustrated in FIG. 10, one vibration element 130 is disposed at a substantially central portion of the operation unit 110, but the number and arrangement of the vibration elements 130 are not limited thereto. For example, the vibration element 130 may be provided so as to correspond to the divided regions D11 to D14 set by the region setting unit 168. In FIG. 13, for example, vibration elements 130 a to 130 d are provided at substantially the center of each divided region D <b> 11 to D <b> 14. By providing the vibration element 130 so as to correspond to the divided areas D11 to D14, the operation surface 120A can be vibrated for each of the divided areas D11 to D14.

  Further, when the input devices 10 and 11 described above have the palm rest P shown in FIG. 2 and the user operates the switch of the palm rest P (not shown) by pushing the palm rest P with the palm of the hand, an operation of pushing the palm rest P is performed. The vibration state of the vibration element 130 may be changed according to whether or not the vibration element is present.

  For example, when the SW detection unit 163 detects the pressing operation of the palm rest P, the vibration control unit 165 controls the vibration element 130 to be in the first vibration state, and the SW detection unit 163 presses the palm rest P. When the operation is not detected, the vibration control unit 165 controls the vibration element 130 to be in the second vibration state. Thereby, for example, the finger can easily slip while the palm rest P is pressed, and the user can easily perform the pressing operation of the palm rest P and the contact operation of the operation unit 110 at the same time.

The vibration state of the vibration element 130 may be changed when the user touches any position on the operation surface 120A of the input devices 10 and 11 described above. For example, when the vibration control unit 165 touches the central portion of the operation surface 120A based on the detection result of the detection unit 161, the vibration control unit 165 has a vibration state different from the vibration state when the region other than the central portion is touched. The vibration element 130 is controlled.

  Thereby, for example, even when the user is performing a contact operation on the operation surface 120A without visually recognizing the input devices 10 and 11, the user can be presented with a predetermined position on the operation surface 120A.

  Further, the input devices 10 and 11 described above may perform user authentication using biometric authentication such as fingerprint authentication and vein authentication. For example, the settings of the input devices 10 and 11 such as the first vibration state and the second vibration state may be changed for each user, and the vibration control unit 165 vibrates the vibration element 130 according to the user authentication result. You may do it.

  In addition, when the switch 140 of the input devices 10 and 11 described above receives an input operation for adjusting the volume of a speaker (not shown) or the temperature of an air conditioner, for example, the tactile sensation given to the user is changed according to the volume and temperature. May be.

  For example, when the user adjusts the volume of the speaker or the temperature of the air conditioner, the vibration control unit 165 switches the operating frequency of the vibration element 130 at a predetermined cycle, that is, the frictional force on the contact surface between the operation surface 120A and the user. Switch between large and small. Thereby, for example, a tactile sensation can be given to the user. Thereby, a tactile sensation according to the volume of the speaker or the set temperature of the air conditioner can be given to the user.

  At this time, for example, as the volume of the speaker increases or the set temperature of the air conditioner increases, the predetermined cycle for switching the operating frequency is lengthened. Further, the predetermined period for switching the operating frequency is shortened as the volume of the speaker decreases or the set temperature of the air conditioner decreases.

  For example, when the user increases the volume of the speaker or increases the set temperature of the air conditioner, the user is given a convex tactile sensation such that the pressing surface 150 is swollen, and the volume of the speaker is decreased, or When the set temperature of the air conditioner is lowered, the user may be given a concave tactile sense that the pressing surface 150 is recessed. As a result, the user can recognize what operation is being performed by tactile sense.

  Further, for example, when the control unit 160 determines that the user has touched a certain part of the operation surface 120A for a predetermined period or more according to the detection result of the detection unit 161, the display control unit 30 and the second display are determined according to the determination result. The control unit 167 may display a predetermined operation menu button on the display unit 20 and the second display unit 190.

  Such an operation menu button is, for example, a circular button, and an image indicating an operation for accepting an input is arranged along the circumference. For example, the user selects an operation by moving the contact position C along the outer periphery of the operation menu button.

  At this time, as the circular button rotates according to the contact operation by the user, it is possible to give a tactile sensation as if actually turning the dial by giving a tactile sensation to the user. For example, the vibration control unit 165 switches the operating frequency of the vibration element 130 at a predetermined cycle, that is, switches the magnitude of the friction force on the contact surface between the operation surface 120A and the user. Thereby, for example, a tactile sensation can be given to the user.

  For example, when an input operation that cannot be canceled if an operation such as complete deletion of a file is executed, the input devices 10 and 11 can cancel the input operation and return to the original state. You may make it give the warning to the effect that there is no tactile sense. For example, as the user's contact position C approaches a button that accepts an operation that cannot be canceled, the frictional force on the operation surface 120A is increased.

  Thereby, as the contact position C of the user approaches the button, the resistance given to the user's finger U can be increased, and a warning can be given to the user by touch.

  Further, when the user performs an input operation on the input devices 10 and 11, for example, when an obstacle is approaching the vehicle, or the user is gazing at the display unit 20 and the input devices 10 and 11. In some cases, it may be necessary to notify the user of the danger. At this time, the input devices 10 and 11 may notify the danger by giving the user a specific tactile sensation.

  For example, when it becomes necessary to notify the user of the danger, the input devices 10 and 11 notify the danger by changing the tactile sensation given to the user greatly. For example, when the vibration control unit 165 controls the vibration element 130 so as to give a large frictional force to the user, the vibration element 130 is controlled so that the frictional force approaches zero. Thereby, a tactile sensation such that the finger U slides suddenly can be given to the user.

  For example, when the vibration control unit 165 controls the vibration element 130 so as to give a small frictional force to the user, the vibration element 130 is controlled so that the frictional force is maximized. Thereby, it is possible to give a tactile sensation that suddenly stops the finger U that has moved smoothly.

  Thus, the input devices 10 and 11 can notify danger by changing the tactile sensation given to the user abruptly. Note that, for example, whether or not an obstacle is approaching the vehicle is determined using a detection result of an unillustrated proximity sensor mounted on the vehicle. Whether or not the user is gazing at the display unit 20 or the input devices 10 and 11 is determined by detecting the user's line of sight based on an image captured by an imaging device (not shown).

  In the above-described embodiment and modification, the shapes of the display unit 20 and the operation unit 110 of the display device 1 are flat, but are not limited thereto. For example, the shape of the display unit 20, the operation unit 110, and the switch 140 of the display device 1 may be a shape having a curved surface. At this time, for example, the tactile sensation given to the user may be changed in accordance with the shapes of the operation unit 110 and the switch 140.
