This xy coordinate system is an orthogonal coordinate system, and its origin is, for example, the upper left corner of the input opening 121 on the paper surface of FIG.

  Moreover, the home position 121a which is a reference position is defined to be the center of the input opening 121 as an example.

(Configuration of the housing 10)
The haptic feedback input device 1 includes a casing 10 having a long and thin box shape, for example, as shown in FIG. The housing 10 is schematically configured to include, for example, a lower housing 11 having a box shape and an upper housing 12 that is a lid of the lower housing 11 and has a plate shape.

  For example, as shown in FIG. 3A, the housing 10 is provided in a center console 90 between a driver seat and a passenger seat of the vehicle 9. The housing 10 is housed in an opening formed in the center console 90 so that, for example, a step does not occur between the surface of the center console 90 and the surface 120 of the upper housing 12. The tactile feedback input device 1 may use the center console 90 as the housing 10. At this time, the input opening 121 is formed in the center console 90.

The touch panel 2 detects a position on the touched detection surface 20 by touching the detection surface 20 with a part of the operator's body (for example, a finger) or a dedicated pen, for example, and coordinates of the detected touch position It is a touch sensor that outputs operation information including such information. For example, the operator can operate the connected electronic device by operating the detection surface 20. As the touch panel 2, for example, a well-known resistive film type, capacitive type touch panel, or the like can be used. The touch panel 2 according to the present embodiment is, for example, a capacitive touch panel.

For example, as shown in FIG. 1B, the touch panel 2 is a plate-shaped touch panel having an area larger than the area of the input opening 121. Longitudinal width W ₂ of the touch panel 2 is, for example, is approximately twice the width W ₁ longitudinal input opening 121. The width H ₂ in the short direction is, for example, approximately twice the width H ₁ of the input opening 121 in the short direction. This is the size of the touch panel 2 necessary to move the operator's finger that has contacted the corner of the input opening 121 to the home position 121 a defined by the input opening 121.

That is, the touch panel 2 moves in the positive direction of the x axis. Further, when the ball screw 57 in the y-axis direction rotates clockwise, the holder 3 moves in the negative direction of the y-axis. That is, the touch panel 2 moves in the negative direction of the y axis.

  The holder 3 is formed using, for example, a metal material such as aluminum or iron, an alloy material containing them, or an alloy material such as stainless steel according to the material of the ball screw 47 and the ball screw 57.

And a ball screw 47. Further, the output shaft of the motor 44 and the ball screw 47 are connected by, for example, a connector 46.

  The motor 44 in the x-axis direction is attached to a pedestal 41 that is movably provided on a rail 40 provided in the lower housing 11 along the y-axis, for example. A rail 42 is disposed opposite to the rail 40, and a pedestal 43 provided with a bearing 430 is movably provided on the rail 42. A tip portion 470 of the ball screw 47 is inserted into the bearing 430 and supports the rotation of the ball screw 47. The rail 40 and the rail 42 are connected by a rigid body (not shown), for example.

  The motor 44 is provided with an encoder 45, for example, as shown in FIG. The encoder 45 is configured, for example, to calculate the movement distance of the motor 44 and output first coordinate information as y-axis coordinate information.

A ball screw 57 is schematically configured. Further, the output shaft of the motor 54 and the ball screw 57 are connected by, for example, a connector 56.

  The motor 54 in the y-axis direction is attached to a pedestal 51 movably provided on a rail 50 provided in the lower housing 11 along the x-axis, for example. A rail 52 is disposed to face the rail 50, and a pedestal 53 provided with a bearing 530 is movably provided on the rail 52. The tip 570 of the ball screw 57 is inserted into the bearing 530 and supports the rotation of the ball screw 57. The rail 50 and the rail 52 are connected by a rigid body (not shown), for example.

  In addition, the motor 54 is provided with an encoder 55, for example, as shown in FIG. For example, the encoder 55 is configured to calculate the movement distance of the motor 54 and output second coordinate information as x-axis coordinate information.

  The motor 44 and the motor 54 are configured to rotate forward and backward based on the first drive signal and the second drive signal output from the control unit 6. The forward rotation is, for example, that the output shaft rotates clockwise as viewed from the motor. The reverse rotation is, for example, that the output shaft rotates counterclockwise when viewed from the motor. In addition, the motor 44 and the motor 54 are DC motors as an example.

(Configuration of control unit 6)
The control unit 6 includes, for example, a CPU (Central Processing Unit) that performs operations and processing on the acquired data according to a stored program, a RAM (Random Access Memory) that is a semiconductor memory, a ROM (Read Only Memory), and the like. Microcomputer. For example, the RAM is used as a storage area for temporarily storing calculation results and the like.

  For example, as shown in FIG. 3C, the control unit 6 decomposes the vector 60 formed by the contact position 20 a and the home position 121 a into an x-axis component 61 and a y-axis component 62, The driving unit 4 is controlled to move the touch panel 2 by a distance corresponding to the x-axis component 61, and the second driving unit 5 is controlled to move the touch panel 2 by a distance corresponding to the y-axis component 62. ing.

  Specifically, for example, the control unit 6 calculates the vector 60 based on the operation information acquired from the touch panel 2 and the position information 70 stored in the memory 7, and further, the vector 60 is calculated in the x-axis direction. The x-axis component 61 and the y-axis component 62 are calculated by decomposing the component into components in the y-axis direction.

  The position information 70 includes, for example, information on coordinates on the touch panel 2 obtained by mapping the center position of the input opening 121 to the touch panel 2. Therefore, for example, when calculating the vector 60, the control unit 6 uses the coordinates obtained by mapping the center position of the input opening 121 when the contact is detected on the touch panel 2 as the coordinates of the home position 121a. To do. In addition, for example, the control unit 6 performs coordinate conversion in accordance with the amount of movement so that coordinates obtained by mapping the center position of the input opening 121 are always obtained while the touch panel 2 is moving.

  The control unit 6 calculates the length (distance) of the x-axis component 61 and generates a first drive signal for driving the motor 44 in the x-axis direction so that the touch panel 2 moves according to the distance. .

  In addition, the control unit 6 calculates the length (distance) of the y-axis component 62, and outputs a second drive signal for driving the motor 54 in the y-axis direction so that the touch panel 2 moves according to the distance. Generate.

  For example, the control unit 6 calculates the movement amount of the touch panel 2 based on the first coordinate information acquired from the first drive unit 4 and the second coordinate information acquired from the second drive unit 5, and the contact position The first drive unit 4 and the second drive unit 5 are controlled so that 20a coincides with the home position 121a.

  For example, after the touch panel 2 is moved, the control unit 6 moves the touch panel 2 to the initial position before driving when the operator's finger leaves the touch panel 2, that is, when contact is not detected. Drive signal and second drive signal are generated.

(Configuration of memory 7)
The memory 7 is, for example, a semiconductor memory. For example, the memory 7 stores position information 70 and display image information 71. Note that the memory 7 may be, for example, the RAM of the control unit 6.

  The display image information 71 is, for example, information on an image displayed on the display device 91 by the electronic device connected to the haptic feedback input device 1. The display image information 71 includes, for example, information on an image determined to present a tactile sensation. For example, when the pointer 93 is positioned at the boundary of the image, the image determined to present a tactile sensation is caused by the vibration generated by the first drive unit 4 and the second drive unit 5 to the operator. It is an image determined to present a tactile sensation.

(Configuration of communication unit 8)
The communication unit 8 is configured to communicate with an electronic device to which the haptic feedback input device 1 is connected, for example. The communication unit 8 is configured to communicate display image information 71, operation information, and the like with the electronic device, for example.

  4A to 4C are schematic views for explaining the operation of the haptic feedback input device according to the first embodiment. Hereinafter, the operation of the haptic feedback input device 1 according to the present embodiment will be described with reference to the flowchart of FIG.

(Operation)
The touch panel 2 of the tactile feedback input device 1 detects whether or not there is a contact of the detection target at a predetermined cycle when the power of the vehicle 9 is turned on and a voltage is supplied.

  When Yes is established in step 1, that is, as shown in FIG. 4A, when the contact of the finger is detected (S1: Yes), the control unit 6 determines the finger based on the operation information and the position information 70. The vector 60 formed by the contact position 20a and the home position 121a where the contact is detected is calculated, and further, the length of the x-axis component 61 and the length of the y-axis component 62 of the vector 60 are calculated (S2).

  Next, the control unit 6 generates a first drive signal and a second drive signal based on the calculated length of the x-axis component 61 and the length of the y-axis component 62, and the first drive unit 4 and It outputs to the 2nd drive part 5 (S3).

  Next, as shown in FIG. 4B, the first drive unit 4 and the second drive unit 5 move the motor 44 and the motor 54 based on the acquired first drive signal and second drive signal. Driven to move the touch panel 2 (S4).

  Next, the control unit 6 calculates the coordinates of the contact position 20a accompanying the movement of the touch panel 2 based on the first coordinate signal and the second coordinate signal, and Yes is established in Step 5, that is, FIG. As shown in (c), when the contact position 20a coincides with the home position 121a due to the movement of the touch panel 2 (S5: Yes), the operations of the first drive unit 4 and the second drive unit 5 are terminated (S6). . For example, when the answer is No in Step 5 (S5: No), the control unit 6 returns to Step 4 so that the contact position 20a and the home position 121a coincide with each other. Are controlled to finely adjust the movement of the touch panel 2.

  After the operator's operation is finished, the control unit 6 generates and outputs a first drive signal and a second drive signal for returning the touch panel 2 to the initial position when the finger contact is not detected for a certain time. Then, the touch panel 2 is moved to the initial position.

(Effects of the first embodiment)
The haptic feedback input device 1 according to the present embodiment enables a manipulation from the reference position by moving the finger to the reference position when touching any position in the operable region of the touch panel 2.

  Specifically, the haptic feedback input device 1 uses the first drive unit 4 and the second drive unit 5 to translate the touch panel 2 in the x-axis direction and the y-axis direction, and thus follows the selected pattern. Compared with the case where the finger is guided by vibration, the finger can be easily moved to the home position 121a. The operator can start the operation from the home position 121a without moving the line of sight to the touch panel 2 because the finger moves to the home position 121a simply by touching the operable area exposed at the input opening 121. , Operability is improved.

  Further, since the tactile feedback input device 1 calculates the movement amount in the x-axis direction and the y-axis direction based on the contact position 20a and the home position 121a, it does not require advanced processing and can be manufactured at low cost. .

  In addition, since the tactile feedback input device 1 translates the touch panel 2 in the x-axis direction and the y-axis direction, the operator first touches the touch panel 2 based on the movement of the touch panel 2 as compared with the case where the touch panel is displaced by vibration. The position is easy to recognize.

(Modification of the first embodiment)
FIGS. 6A and 6B are schematic views for explaining a modification of the home position of the haptic feedback input device. FIG. 6A shows an image of 50 sounds displayed on the display device 91, and FIG. 6B is a top view of the input opening 121.

  Although the home position 121a in the above is the center of the input opening 121, it is not limited to this. As an example, the home position 121a of the modification shown in FIGS. 6A and 6B is the position of the input opening 121 corresponding to the button image 94 indicating “A”. In this case, when the operator touches the touch panel 2, the finger moves to the home position 121a, and the operation can be started from the button image 94 indicating “A”.

[Second Embodiment]
The second embodiment is different from the first embodiment in that the touch panel 2 moves only in one direction by the first drive unit. In the following embodiments, portions having the same functions and configurations as those of the first embodiment are denoted by the same reference numerals as those of the first embodiment, and description thereof is omitted.

  FIG. 7A is a top view of the haptic feedback input device according to the second embodiment, and FIG. 7B is a diagram VII (b) -VII (b) shown in FIG. 7A of the haptic feedback input device. It is sectional drawing which looked at the cross section cut | disconnected by the line from the direction of the arrow. As an example, the tactile feedback input device 1 can be used as an operation unit for setting a set value of an air conditioner or the like.

  The haptic feedback input device 1 according to the present embodiment is mainly provided in the housing 10 in which the input opening 121 is formed and the detection surface 20 is exposed from the input opening 121, and the detection target is A flexible touch sensor 200 as a detection unit that detects the contact position 20a of the contacted detection surface 20, a first drive unit 4 that moves the flexible touch sensor 200 in the x-axis direction, and the first drive unit 4 are controlled. And a control unit 6 that moves the flexible touch sensor 200 in the x-axis direction so that the contact position 20a on the flexible touch sensor 200 coincides with the home position 121a defined by the input opening 121. .

  The haptic feedback input device 1 is configured to detect an operation in the x-axis direction, for example, as shown in FIG. Note that the positive direction of the x-axis is, for example, the right side of the paper surface of FIGS. 7A and 7B, and the negative direction is the left side.

  Further, as an example, the input opening 121 according to the present embodiment is assumed to have a length in the vertical direction on the paper surface of FIG. 7A that is about the width of a finger that contacts the flexible touch sensor 200. Therefore, for example, the operator can perform an operation only in the left-right direction of the plane of FIG. 7A, that is, in the x-axis direction.

  The flexible touch sensor 200 is, for example, a touch sensor in which detection electrodes are formed on a flexible substrate. The flexible touch sensor 200 has, for example, a shape in which a front end and a terminal end are connected as shown in FIG.

  For example, as shown in FIG. 7B, the first drive unit 4 can rotate to the motor 400, the wheel 401 attached to the output shaft of the motor 400, the rotation support unit 402, and the rotation support unit 402. And a wheel 403 supported by the motor.

  For example, the motor 400 is configured to rotate clockwise and counterclockwise on the paper surface of FIG. The wheel 401 and the wheel 403 are inserted into a ring formed by the flexible touch sensor 200 and are arranged apart from each other so that the detection surface 200a of the flexible touch sensor 200 is flat. This flat portion is exposed from the input opening 121.

  In the tactile feedback input device 1, for example, when the wheel 401 rotates with the clockwise rotation of the motor 400, the flexible touch sensor 200 exposed to the input opening 121 moves in the positive direction of the x axis. Here, the clockwise rotation of the motor 400 on the paper surface of FIG. 7B is referred to as forward rotation, and the counterclockwise rotation is referred to as reverse rotation. When the motor 400 rotates in the forward direction, the flexible touch sensor 200 exposed to the input opening 121 moves in the positive direction of the x axis, and moves in the negative direction of the x axis when performing reverse rotation.

  The tactile feedback input device 1 is configured to move a finger to a home position 121a that is the center of the input opening 121 when, for example, the finger contacts the contact position 20a shown in FIG.

  That is, for example, the control unit 6 rotates the motor 400 forward based on the contact position 20a and the home position 121a, and moves the contact position 20a in the positive direction of the x axis so as to coincide with the home position 121a.

(Effect of the second embodiment)
Even if the tactile feedback input device 1 according to the present embodiment can be operated only in a one-dimensional direction, the finger is moved to the home position 121a, and the operation from the home position 121a is enabled.

[Third Embodiment]
The third embodiment is different from the above-described embodiments in that the tactile sensation by vibration is presented at the boundary of the image determined to present the tactile sensation by vibration.

  FIG. 8 is a schematic diagram of a display device for explaining a haptic presentation operation of the haptic feedback input device according to the third embodiment.

  The control unit 6 of the haptic feedback input device 1 according to the present embodiment includes the first driving unit 4 at the boundary of an image that is displayed on the connected display device 91 and is determined to present a haptic sense caused by vibration. And it is comprised so that the 2nd drive part 5 may be controlled and a vibration may be added to the touch panel 2. FIG.

  For example, as shown in FIG. 8, when an image (icon 95 and icon 96) determined to present two haptics is displayed on the display screen 92 of the display device 91, the surroundings of the icon 95 and the icon 96 are displayed. In FIG. 8, a boundary 95a and a boundary 96a indicated by dotted lines in FIG.

  For example, when the pointer 93 crosses the boundary, the control unit 6 controls the first driving unit 4 and the second driving unit 5 to vibrate the touch panel 2 and presents a tactile sensation to the operator.

  Specifically, for example, when the icon 95 and the icon 96 that are determined to present a tactile sensation are displayed on the display screen 92 and the pointer 93 reaches the boundary 96a of the icon 96 by the operation of the operator, the control is performed. The unit 6 generates and outputs a first drive signal and a second drive signal that vibrate the motor 44 and the motor 54 based on the operation information and the display image information 71. Based on the first drive signal and the second drive signal, the motor 44 and the motor 54 repeat forward and reverse rotations to vibrate the touch panel 2. The operator can recognize the icon 96 by feeling this vibration with a finger, that is, by presenting this tactile sensation.

(Effect of the third embodiment)
The tactile feedback input device 1 according to the present embodiment presents a tactile sensation due to vibration at a boundary of an image determined to present a tactile sensation due to vibration. By presenting the tactile sensation, the operator can feel the presence of an image to be selected with a finger without moving the line of sight to the touch panel 2 and the display device 91.

  In each of the above-described embodiments, the haptic feedback input device 1 presents tactile sensation by vibration, that is, haptic feedback, for example, in order to make the operator recognize that a selectable image has been selected by the pointer 93 or the like. It is good also as a structure provided to an operator.

  Further, the haptic feedback input device 1 may be configured to apply different vibrations for each image, for example.

  Further, the tactile feedback input device 1 may have a configuration in which, for example, when the finger is removed from the operable region displayed on the display device 91, vibration is applied to the touch panel 2 and a tactile sensation is presented to the operator.

  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.
