[Embodiment]
(Configuration of display input device 1)
FIG. 1A is an exploded perspective view of a display input device according to an embodiment, and FIG. 1B is a schematic view of the inside of a vehicle on which the display input device is mounted. FIG. 2 is a block diagram of the display input device according to the embodiment. In each drawing according to the embodiment, the ratio between parts may differ from the actual ratio.

  As shown in FIGS. 1A, 1B, and 2, for example, the display input device 1 mainly includes a display unit 10 that displays a plurality of selectable images 110 that can be selected, and a selectable image 110. The detection unit 12 that detects the operation performed and calculates the detection point, and the determination area for determining the selection of the selectable image 110 are the selectable image 110 and the selectable image 110. The defining unit 28 that prescribes that the distance is not constant is compared with the detection point and the determination region. When the detection point is inside the determination region, the first process is performed, and the detection point is outside the determination region. When there is a processing unit 30 that performs the second process, the vibration generating unit 42 that performs the first presentation based on the first process and performs the second presentation based on the second process, Are generally configured.

  The display input device 1 is schematically configured to include, for example, a display input ECU (Electronic Control Unit) 20, a memory 38, and a communication unit 40.

  As an example, the display input device 1 can operate electronic devices such as a navigation device, an air conditioner, an audio device, and a driving support device mounted on the vehicle 6, and can input characters and the like. For example, a character or the like is input by performing a tracing operation on the operation surface 122 of the detection unit 12 of the display input device 1 with a fingertip or the like to be detected, and a selectable image 110 as a selectable region displayed on the display unit 10. By performing a push-in operation (hereinafter referred to as a press operation) above, it is possible to perform an input operation of characters, symbols, etc. displayed as the selectable image. The input characters and the like are displayed on a center display 62 described later, for example.

  For example, as shown in FIG. 1B, the display unit 10 of the display input device 1 is disposed on a center console 60 provided between a driver seat and a passenger seat. Further, the detection unit 12 corresponding to the display unit 10 is arranged so as to overlap the display unit 10. That is, the display input device 1 is configured as a touch panel as an example. In the present embodiment, as described above, the display unit 10 and the detection unit 12 are arranged on the same surface, but the display unit 10 and the detection unit 12 can be arranged separately. . For example, instead of the display unit 10, an image corresponding to the detection unit 12 may be displayed on the center display 62.

(Configuration of display unit 10)
The display unit 10 is a known liquid crystal display such as a TFT (Thin Film Transistor) type. For example, the display unit 10 is connected to a display controller 26 described later of the display input ECU 20, and displays an image on the display screen 100 based on a display signal output from the display controller 26.

(Configuration of the detection unit 12)
The detection unit 12 is, for example, a touch sensor that detects a position (detection point) on the touched operation surface 122 when the operation surface 122 is touched with a part of the operator's body (for example, a finger). For example, the operator can input characters and symbols by performing operations such as touching and tracing on the operation surface 122. Further, the input content is determined by this input operation, and the connected electronic device can be operated. As the detection unit 12, for example, a known touch sensor such as a capacitance method, a resistance film method, an infrared method, or a SAW method can be used.

  The detection unit 12 according to the present embodiment detects a change in current that is inversely proportional to the distance between the sensor wire 123 and the sensor wire 124 and the finger due to, for example, the finger approaching or touching (contacting) the operation surface 122. It is a capacitive touch sensor that outputs information.

  In the detection unit 12, for example, as shown in FIG. 1A, a sensor wire 123 and a sensor wire 124 are arranged on a sensor substrate 120. The sensor substrate 120 is formed in a plate shape using a material having high transparency (for example, light transmittance of 90% or more) such as glass or PET (Polyethylene terephthalate). Moreover, the detection part 12 is provided with the drive part 14 and the touch detection part 16, for example, as shown in FIG.

  The sensor wire 123 and the sensor wire 124 are formed by using, for example, a transparent electrode ITO (Indium Tin Oxide).

  For example, as shown in FIG. 2, the sensor wire 123 and the sensor wire 124 are arranged along the vertical direction and the horizontal direction of the paper surface. In the present embodiment, the horizontal direction in FIG. 2 is the x axis, the vertical direction is the y axis, and the upper left of the detection unit 12 is the origin.

  In the x-axis direction, for example, m sensor wires 123 are arranged at equal intervals so as to be orthogonal to the x-axis. This m is, for example, a positive integer. For example, the sensor wire 123 is electrically connected to the drive unit 14 and the touch detection unit 16. The drive unit 14 supplies a voltage to the sensor wire 123, for example.

  In the y-axis direction, for example, n sensor wires 124 are arranged at equal intervals so as to be orthogonal to the y-axis. This n is, for example, a positive integer. For example, the sensor wire 124 is electrically connected to the drive unit 14 and the touch detection unit 16. The drive unit 14 supplies a voltage to the sensor wire 124, for example. The touch detection unit 16 sequentially connects to the sensor wire 123 and the sensor wire 124 according to the clock signal generated by the clock signal generation unit 36 and reads the capacitance. For example, as shown in FIG. 2, this voltage is supplied from the power source of the vehicle 6 or adjusted to a voltage necessary for the operation of the display input device 1.

  For example, the sensor wire 123 in the x-axis direction is formed in a layer closer to the operation surface 122 than the sensor wire 124 in the y-axis direction. The sensor wire 123 is electrically insulated from the sensor wire 124, for example.

Here, the coordinates of the x-axis are indicated by x ₁ to x _m from the left to the right, with subscript numbers ( _{1 to m} ) added to x. The coordinates of the y-axis is denoted by the subscript numbers (1 to n) to y, from top to bottom and indicates the _y 1 ~y _n.

Specifically, the touch detection unit 16 is, for example, _x 1 _~x m in the x-axis direction of the sensor wire 123 in the order of _y 1 ~y _n in the y-axis direction of the sensor wire 124 to read the capacitance It is configured.

Touch detection unit 16 is, for example, on the basis of the read value of the capacitance of each sensor wire 123 and the sensor wire 124 (capacitance value), the capacitance value of the coordinate value (x _m, capacitively y _n A capacitance value, t) is generated, and a detection point is calculated from this coordinate value. The touch detection unit 16 is configured to output, for example, detection information including the calculated coordinates of detection points to the display input ECU 20. The time t indicates, for example, the time when the clock signal is output. As a coordinate calculation method, for example, a known method such as a method using a weighted average is used.

(Configuration of display input ECU 20)
The display input ECU 20 includes, for example, a CPU (Central Processing Unit) that performs operations and processes on acquired data according to a program, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. For example, a program for operating the CPU is stored in the ROM. For example, the RAM is used as a storage area for temporarily storing calculation results and the like.

  The display input ECU 20 includes, for example, a control unit 22, a display image generation unit 24, a display controller 26, a definition unit 28, a processing unit 30, a device control unit 32, a sensor controller 34, and a clock signal generation unit. 36, and is schematically configured.

(Configuration of control unit 22)
For example, the control unit 22 determines an operation performed based on the result determined by the processing unit 30 and the state of the switch unit 125. Specifically, for example, when the detection point is inside the determination region by the processing unit 30 and the switch unit 125 is in the ON state from the switch signal acquired from the switch unit 125, the control unit 22 enters the determination region. It is determined that the corresponding selectable image has been selected and determined. The control unit 22 is configured to output the determination result to the device control unit 32, for example.

(Configuration of display image generation unit 24)
The display image generation unit 24 is configured to, for example, read image information 280 that is information such as the selectable image 110 to be displayed on the display unit 10 from the memory 38, generate a display signal, and output the display signal to the display controller 26. Yes.

(Configuration of display controller 26)
For example, the display controller 26 is configured to control the display unit 10 to display an image based on the display signal on the display unit 10.

  Here, the image information 280 is acquired from the electronic device via the communication unit 40 as an example, and is generated by the defining unit 28 based on display image information to be displayed on the display unit 10. The image information 280 includes, for example, 50-tone display as shown in FIG. 1A and image data such as a frame surrounding each character. The image information 280 includes various display data such as a menu screen and a map screen of an electronic device to be controlled. Furthermore, the image information 280 includes, for example, information related to a display area and a determination area described later.

(Configuration of the defining part 28)
FIG. 3 is a schematic diagram for explaining a determination region according to the embodiment. The boundary line 5, the determination area 114a, and the determination area 114b illustrated in FIG. 3 are not actually displayed on the display unit 10.

  For example, the defining unit 28 generates the image information 280 based on the acquired display image information. That is, as an example, as shown in FIG. 3, the defining unit 28 includes image information including information on a frame image, a character image, a determination region, and a non-determination region as information on the selectable image 110 to be displayed on the display unit 10. 280 is generated. Hereinafter, as an example of the selectable image 110, description will be given using the adjacent selectable image 111a and the selectable image 111b.

  The information of the selectable image 111a included in the image information 280 includes, for example, information on the frame image 112a, the character image 113a, the determination area 114a, and the non-determination area 115. The selectable image 111a is selected by an operation on the detection unit 12, and the selection is determined by pushing the detection unit 12. When the selection is determined, the display input device 1 displays, for example, “A” of 50 sounds on the input frame of the display unit 10 or the center display 62.

  Further, the information on the selectable image 111b included in the image information 280 includes, for example, information on the frame image 112b, the character image 113b, the determination area 114b, and the non-determination area 115. The selectable image 111b is selected by an operation on the detection unit 12, and the selection is determined by pushing the detection unit 12. When the selection is determined (hereinafter referred to as “selection determination”), the display input device 1 displays, for example, “50” of 50 sounds on the input frame of the display unit 10 or the center display 62. In the following, the selectable image 111a will be mainly described, but the selectable image 111b and other selectable images have the same functions and configurations.

  The frame image 112 a and the character image 113 a are images displayed on the display unit 10. The frame image 112a is an image provided as a guideline for selecting and determining the character image 113a displayed in the frame, for example. In the present embodiment, for example, as shown in FIG. 3, it is assumed that the frame image 112a of the selectable image 111a and the frame image 112b of the selectable image 111b overlap. The character image 113a is displayed on the display unit 10 so as to be displayed in the frame image 112a, for example.

  The determination area 114a is an area defined by the defining unit 28. When the detected detection point is inside the determination area 114a, it is determined that the selectable image 111a is selected. For example, when there is a detection point inside the determination region 114a, the display input device 1 controls the vibration generating unit 42 to generate vibration and presents a tactile sensation to the operator. The determination area 114a is defined beyond the boundary between adjacent selectable images, for example.

  Here, the determination area is defined so that the distance from the selectable image is constant, and has an area smaller than the selectable image in order to prevent the adjacent selectable image and the determination area from overlapping each other. When it is defined to be a determination region, when the operator's finger is operated along the boundary line 5 shown in FIG. 3, the detection point does not belong to the inside of the determination region, so that a tactile sense due to vibration is not presented. There is. Although this problem is the operation in the vertical direction of FIG. 3 above, the same phenomenon may occur in the horizontal direction of FIG.

  Therefore, as an example, the defining unit 28 of the present embodiment defines a determination region 114a in which the distance from the selectable image 111a is not constant as illustrated in FIG. In other words, in the determination area 114a, for example, a portion that is convex toward the boundary line 5 is concave in the determination area 114b, and the area between the determination area 114a and the determination area 114b facing each other via the boundary line 5 is A zigzag region having a width d is formed. However, the region formed by the corner of the determination region 114a and the corner of the determination region 114b is not limited to this.

  Since the determination area 114a whose distance from the selectable image 111a is not constant is defined, the convex portion of the determination area 114a toward the boundary line 5 can be defined so as to be in contact with the boundary line 5, for example. Become. By being defined in this way, even when the boundary line 5 is operated, the detection point exists in one of the adjacent determination areas, and thus the detection point is on the selectable image. It is possible to generate a vibration indicating that.

(Configuration of processing unit 30)
For example, the processing unit 30 compares the detection point with the determination region, performs the first process when the detection point is inside the determination region, and when the detection point is in the non-determination region outside the determination region. The second process is performed. Note that the inside of the determination area includes the boundary between the determination area and the non-determination area.

  The first presentation according to the present embodiment is, for example, adding vibration by the vibration generator 42, and the second presentation is stopping vibration by the vibration generator 42. That is, when the operator performs a tracing operation on the operation surface 122 of the detection unit 12, when the detection point enters the determination region, the display input device 1 passes the vibration generation unit 42 to the detection unit 12. A vibration is applied and a tactile sensation is presented to the operator.

  Here, as a modification, the display input device 1 may be configured to stop the vibration generated by the vibration generating unit 42 as the first presentation and add the vibration generated by the vibration generating unit 42 as the second presentation. . That is, in this case, when the operator is performing a tracing operation on the operation surface 122 of the detection unit 12, the display input device 1 sets the vibration generation unit 42 when the detection point is outside the determination region. Then, vibration is applied to the detection unit 12 to present a tactile sense, and when the detection point enters the determination region, the vibration is stopped.

(Configuration of device control unit 32)
The device control unit 32 is based on the operation determined by the control unit 22 and the device information 320 that defines the function assigned to the operation, and the navigation device, the air conditioner, the audio device, and the operation mounted on the vehicle 6. A device control signal for controlling an electronic device such as a support device is generated and output to the corresponding electronic device via the communication unit 40.

(Configuration of sensor controller 34)
For example, the sensor controller 34 controls the detection unit 12. Specifically, it is configured to control the voltage to be supplied, control the supply time, control the readout timing of the capacitance, and the like.

(Configuration of clock signal generator 36)
The clock signal generator 36 generates, for example, a clock signal necessary for the operation of the display input device 1 and supplies the clock signal to each unit.

(Configuration of memory 38)
The memory 38 is a semiconductor memory, for example. The memory 38 stores image information 280 and device information 320. The device information 320 is information on an electronic device to which the display input device 1 is connected. The memory 38 may be configured using a memory such as a ROM of the display input ECU 20, for example.

(Configuration of communication unit 40)
The communication unit 40 is configured to be able to communicate with a connected electronic device, for example. The device information 320 is stored in the memory 38 via the communication unit 40, for example. The communication unit 40 is connected to the electronic device by, for example, wired or wireless.

(Configuration of vibration generating unit 42)
As shown in FIG. 1A, the vibration generation unit 42 is disposed so as to be in contact with the detection unit 12, and vibrates the operation surface 122 to which a finger approaches or touches (contacts). Make a tactile presentation. The vibration generating unit 42 can use various actuators such as a piezo (electrostrictive element), a solenoid, a motor, and an electromagnetic coil, for example. A plurality of vibration generators 42 may be provided.

(Configuration of switch unit 125)
For example, as shown in FIG. 2, the switch unit 125 is attached to the back surface 121 of the display unit 10 or the back surface 101 of the detection unit 12. In addition, each of the switch units 125 is electrically connected to the display input ECU 20, for example. When the operator selects (selects) a desired selectable image 110 displayed on the display unit 10 and performs an operation (pressing operation) to push in the detecting unit 12, the switch unit 125 is turned on. As a result, a pressing operation following the selection operation is possible.

  For example, various switches can be used as the switch unit 125 as long as the switch is turned on or off by a pressing operation such as a tact switch. In the present embodiment, for example, as shown in FIG. 2, switch portions 125 are attached to the four corners of the back surface 101 of the display unit 10 or the back surface 121 of the detection unit 12, and a pressing operation is performed on the detection unit 12. When at least one switch outputs a switch signal indicating an ON state, the control unit 22 determines that a pressing operation has been performed.

  Hereinafter, the operation of the display input device 1 according to the present embodiment will be described with reference to the flowchart shown in FIG.

(Operation of display input device 1)
First, the defining unit 28 acquires display image information via the communication unit 40 (S1).

  Next, the prescription | regulation part 28 sets a determination area | region based on the acquired display image information, and produces | generates the image information 280 (S2). The generated image information 280 is stored in the memory 38.

  Next, the display image generation unit 24 generates a display signal based on the image information 280 acquired from the memory 38 and outputs the display signal to the display controller 26. The display controller 26 outputs the acquired display signal to the display unit 10 and causes the display unit 10 to display an image (S3).

  Next, the detection part 12 reads the electrostatic capacitance for every sensor wire based on a clock signal, and calculates a detection point (S4).

  Next, the processing unit 30 compares the calculated detection point with the determination region. When the detection point is inside the determination region (S5: Yes), the processing unit 30 performs the first process on the vibration generation unit 42. .

  Next, the vibration generation unit 42 applies vibration to the first presentation based on the first process, that is, the detection unit 12 (S6). Note that while the vibration generating unit 42 performs the first presentation, the display input device 1 may be configured to perform a display indicating a state in which the selectable image is selected. This display is a reverse display as an example.

  Here, in Step 5, when the processing unit 30 determines that the detection point is not inside the determination region (S5: No), the processing unit 30 performs the second process on the vibration generating unit 42. The vibration generating unit 42 stops the second presentation (S7) based on the first process, that is, the vibration, and proceeds to step 4. Therefore, vibration is not added to the detection unit 12 while the detection point is located outside the determination region.

  The operations from step 4 to step 7 are performed according to the cycle of the clock signal, for example, until the operation is completed or the supply of power is stopped. When a new screen is displayed, the process returns to step 1 for processing regardless of which step is executed.

  Next, the control unit 22 determines whether or not a pressing operation has been performed based on the switch signal. When the control unit 22 determines that the pressing operation has been performed, the control unit 22 generates a device control signal based on the device information 320 and the selectable image selected and determined, and the display input device 1 is connected via the communication unit 40. Output to the electronic device.

(Effect of embodiment)
The display input device 1 according to the present embodiment can present a tactile sensation even when the detection target moves between adjacent selectable regions (selectable images). For example, when the determination region matches a selectable image, the boundary between adjacent selectable images overlaps. In order to avoid this overlap, it is necessary to make the determination area smaller than the selectable image. However, there is a problem that a tactile sensation is not presented when the finger passes between the determination areas. However, since the display input device 1 according to the present embodiment defines a determination region in which the distance from the selectable image is not constant, the determination region is set without overlapping the vicinity of the boundary between the selectable image and the selectable image. It is possible to avoid the problem of the finger passing between the determination areas, and to present a sense of touch reliably.

  Since the display input device 1 can add vibration as the first presentation, the display unit 10 and the detection unit 12 for executing a desired operation as compared with the case where the display input device 1 presents by flashing light or a change in an image. Can be suppressed.

(Modification)
FIGS. 5A and 5B are schematic diagrams for explaining a modified example of the determination region.

  The modified example shown in FIG. 5A is different from the above-described embodiment in that a determination area and a detection area for detecting selection of a selectable image are separately defined. In this modification, as an example, one side of the frame image 112a of the selectable image 111a and one side of the frame image 112b of the selectable image 111b overlap.

  As shown in FIG. 5A, for example, the selectable image 111a is roughly configured to include a frame image 112a, a character image 113a, a determination area 114a, and a detection area 116a. Further, for example, as shown in FIG. 5A, the selectable image 111b is schematically configured to include a frame image 112b, a character image 113b, a determination area 114b, and a detection area 116b.

  Each detection region has a larger area than the corresponding determination region, in other words, so as to include the determination region.

  In the detection area 116a and the detection area 116b, for example, when the detection point exists inside the area and the detection unit 12 is pressed, the displayed characters are input to a predetermined input frame. This is an area where For example, the defining unit 28 generates the image information 280 including the detection area 116a and the detection area 116b based on the display image information.

  In the display input device 1 according to this modified example, since the determination area and the detection area are set separately, the finger is displaced and deviates from the determination area by performing a pressing operation near the convex vertex of the determination area. The problem that is not made can be avoided.

  Further, the modification shown in FIG. 5B is different from the above-described embodiment and modification in that a determination area is set outside the frame image.

  In this modification, the frame image 112a of the selectable image 111a and the frame image 112b of the selectable image 111b are arranged so as not to overlap.

  As shown in FIG. 5B, the determination area 114a of the selectable image 111a is set by the defining unit 28 outside the frame image 112a and beyond the boundary line 5, for example. The determination area 114b of the selectable image 111b is set outside the frame image 112b and beyond the boundary line 5 by the defining unit 28, for example. However, the determination area 114a and the determination area 114b are set so as not to overlap.

  In the display input device 1 according to this modified example, when the selectable image 111a and the selectable image 111b are arranged apart from each other and a tracing operation along the boundary line 5 is performed, the determination area exceeds the boundary line 5. Since the 114a and the determination area 114b are set, a tactile sensation can be surely presented.

  It should be noted that the selectable images and determination areas according to the above-described embodiments and modifications are examples, and the shapes thereof are not limited and can be changed.

  As mentioned above, although some embodiment and modification of this invention were demonstrated, these embodiment and modification are only examples, and do not limit the invention based on a claim. These novel embodiments and modifications can be implemented in various other forms, and various omissions, replacements, changes, and the like can be made without departing from the scope of the present invention. In addition, not all combinations of features described in these embodiments and modifications are necessarily essential to the means for solving the problems of the invention. Furthermore, these embodiments and modifications are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalents thereof.
