Shall be assigned. Note that the number, arrangement, and shape of the touch sensors 311 are not limited to this, and can be changed according to the application.

  In addition, the input unit 31 transmits an operation signal (output signal) based on a gesture input to the touch pad 310 by the operator to simulate a predetermined gesture (predetermined locus) to the control unit 30.

  Note that the gesture refers to an operation of directly touching the touch pad 310, but the case where the capacitance of the touch sensor 311 changes sufficiently to be determined to be in contact is also included in the gesture.

(About judgment part)
4A is a schematic diagram of a left circle gesture according to the embodiment of the present invention, FIG. 4B is a schematic diagram of an upper straight gesture, and FIG. 4C is a schematic diagram of a right straight gesture. FIG. 5A is a schematic diagram of a first gesture according to the embodiment of the present invention, and FIG. 5B is a schematic diagram regarding determination of a gesture. For example, the circle in FIG. 5B is a point obtained by dividing the left circle gesture 50 described in the gesture dictionary 350 into 12 parts for determination, and the triangle is a point of the calculated touch coordinates. The number in the middle indicates the order of reference, and the number in the triangle indicates the calculated order. Note that the number of divided points is not limited to 12, but can be changed according to the application, and the touch coordinates calculated in a predetermined period are not limited to 12.

  As an example, the determination unit 32 calculates the touch coordinates in the XY coordinate system every cycle (for example, 16 ms) based on the operation signal from the input unit 31 acquired via the control unit 30, and in a predetermined period. The obtained plurality of touch coordinates are stored in the storage unit 35 via the control unit 30 as a touch coordinate group 351 arranged in the order of the acquired time.

  Here, as an example, the touch coordinates are calculated based on the coordinates of the touch sensor 311 in the on state, and a method for calculating an average value of the coordinates of the touch sensor 311 in the on state, and in the on state. A weight function is assigned to the touch sensor 311 and is calculated by a known method such as a method of calculating by weighted average.

  The predetermined period is, for example, a period from when the touch sensor 311 in the on state is detected for the first time among all the touch sensors 311 to when all the touch sensors 311 are in the off state, and is not limited thereto. .

  The determination unit 32 includes the calculated touch coordinate group 351 and the left circle, upper straight line, and right straight gesture (a plurality of trajectories) 50, 51, 52, and the like shown in FIGS. 4 (a), 4 (b), and 4 (c). The gesture input using the described gesture dictionary 350 is determined based on a predetermined criterion.

  Here, the left circle gesture 50 is a gesture input so as to draw a circle in a clockwise direction, and the upper straight line gesture 51 is a gesture input so as to draw a straight line in the upward direction. The right straight gesture 52 is a gesture input so as to draw a straight line from the left direction to the right direction. Although not shown, a gesture that draws a circle in a counterclockwise direction as a gesture opposite to the previous gesture is called a right circle gesture, and a gesture that is input so as to draw a straight line downward is called a lower straight line gesture. The gesture input so as to draw a straight line from the left to the right is called a left straight gesture. The gesture is not limited to this, and an oblique gesture or the like can be added / deleted depending on the application.

  As an example, when the first gesture 53 illustrated in FIG. 5A is input to the touch pad 310, the determination unit 32 performs the gesture points described in the gesture dictionary 350 as illustrated in FIG. 5B. And the distances L1 to L12 with respect to the points constituting the touch coordinate group 351 are compared in numerical order, and the distances L1 to L12 are based on the obtained touch coordinate group 351 when they are within two threshold conditions. It is determined that the gesture is a left circle gesture 50.

  Here, the two threshold conditions are, for example, the number of points within the distance threshold in which the average distance of the distances L1 to L12 is set and the distance is shorter than the average distance. It is within the threshold value (for example, the distance is less than the average distance at half or more points).

  For example, the determination unit 32 calculates a determination value by multiplying the degree of coincidence, which is the ratio of the number of points that satisfy two threshold conditions, by a determination criterion (usually 1) as a predetermined criterion. To do. The degree of coincidence is “1” when all the points satisfy the predetermined criterion, and is “0.5” when half of the points satisfy the predetermined criterion. It shall be calculated for all described gestures.

  In addition, when the calculated determination value is equal to or greater than the determination threshold value (for example, 0.7) in the determination criterion information 352, the determination unit 32 inputs the first gesture illustrated in FIG. 5B as an example. 53 is determined as a left circle gesture 50.

  The determination criterion information 352 is created for each operator who is authenticated by the portable device 5, and the determination unit 32 determines a gesture input based on the determination criterion information 352 of the operator authenticated by the authentication unit 34.

  The determination method is not limited to the above example, and may be determined by a known shape recognition method such as pattern matching, and the matching degree calculation method is also changed based on the selected shape recognition method. good.

(About the Standard Change Department)
For example, the reference changing unit 33 changes the determination reference information 352 stored in the storage unit 35 based on the first and second conditions. Details of the first and second conditions will be described in the description of the operation.

(Operation)
Hereinafter, the operation of the input device according to the present embodiment will be described in detail with reference to the drawings.

(About gesture judgment operation)
First, as an example, an operation when the first gesture 53 described above is input to the input unit 31 by a driver as an operator, that is, when there is a gesture corresponding to the gesture dictionary 350 will be described with reference to the flowchart of FIG. Note that the determination value is calculated with the determination criterion “1”.

  When the driver approaches the vehicle 1 with the portable device 5, the authentication unit 34 of the vehicle 1 communicates with the portable device 5 and starts an authentication operation.

  The authentication unit 34 releases the door lock of the vehicle 1 when the authentication operation with the portable device 5 is completed and the authentication is established.

  The driver gets into the vehicle 1 and turns on the power supply system of the vehicle 1. At this time, the control unit 30 reads the criterion information 352 for the driver authenticated by the portable device 5 (S1).

  The input unit 31 scans the electrode 313 based on a predetermined cycle to acquire an on / off state, and outputs it to the control unit 30 (S2).

  With the intention of inputting the left circle gesture 50 shown in FIG. 4A to the touch pad 310 while grasping the steering wheel 21, the driver puts the first gesture 53 shown in FIG. Input (S3).

  The determination unit 32 calculates touch coordinates in a predetermined period based on the input of the first gesture 53, and stores the calculated touch coordinates in the storage unit 35 via the control unit 30 as the touch coordinate group 351 (S4). ).

  The determination unit 32 determines that a gesture is input to the touch pad 310 when the amount of movement of the touch coordinates is above a predetermined threshold based on the touch coordinate group 351 calculated in a predetermined period (S5; Yes). Determine (S6).

  The determination unit 32 calculates the degree of coincidence with the gesture dictionary 350 based on the input touch coordinate group 351 of the gesture and the determination criterion information 352 corresponding to the authentication information recognized by the authentication unit 34, and the calculated left When the determination value based on the degree of coincidence of the circle gesture 50 exceeds the determination threshold value, the input gesture is determined as the left circle gesture 50 (S7).

  The control unit 30 controls the controlled device, that is, the display device 4 based on the determination of the left circle gesture 50 by the determination unit 32, and executes the command assigned to the left circle gesture 50 (S8). The process for the gesture made is finished.

  Here, in step S5, when the movement amount of the touch coordinates is below a predetermined threshold based on the touch coordinate group 351 calculated in the predetermined period (S5; No), the determination unit 32 determines that the touch pad 310 is not touched. It is determined that touch or area touch is input (S9).

  As an example, the touch and the area touch are that the same touch sensor 311 of the touch pad 310 is in an on state for a certain period of time, and an area touch is a state in which more touch sensors 311 are in an on state than a touch. It shall be.

  After determining the touch or the area touch, the determination unit 32 determines “long press” or “short press” based on the time during which the same touch sensor 311 is in an on state, that is, the length of the staying time (S10). The unit 30 controls the controlled device based on the determination (S8).

(About judgment operation when there is no corresponding gesture)
FIG. 7A is a schematic diagram of the second gesture according to the embodiment of the present invention, and FIG. 7B is a schematic diagram of the third gesture. In the following, a case where the gesture input to the touch pad 310 is determined to have no corresponding gesture (first result) by the determination unit 32 will be described with reference to the flowchart shown in FIG. Portions overlapping with the above-described determination operation are described in a simplified manner.

  The driver inputs the second gesture (first trajectory) 54 shown in FIG. 7A with the intention of inputting the left circle gesture 50 shown in FIG. 4A to the touch pad 310.

  The determination unit 32 calculates the degree of coincidence with the gesture dictionary 350 based on the input touch coordinate group 351 of the second gesture 54 and the determination criterion information 352 corresponding to the authentication information recognized by the authentication unit 34. The determination criterion at this time is “1”.

  For example, when the left circle gesture 50, the upper straight gesture 51, and the right straight gesture 52 shown in FIGS. 4A, 4 </ b> B, and 4 </ b> C are described in the gesture dictionary 350, the determination unit 32 performs these gestures. As an example, the degree of coincidence of the left circle gesture 50 is calculated as 0.6, the degree of coincidence of the upper straight line gesture 51 is 0.3, and the degree of coincidence of the right straight line gesture 52 is calculated as 0.1. The determination threshold value based on the determination criterion information 352 is 0.7.

  At this time, the determination unit 32 determines that there is no corresponding gesture because there is no determination value exceeding the determination threshold (S20; determination step).

  Since there is no corresponding gesture, the determination unit 32 uses the gesture having the highest degree of coincidence, that is, the information of the left circle gesture 50 and the degree of coincidence of 0.6 as the history information 353 together with the authentication information of the portable device 5. 30 in the storage unit 35 (S21).

  The driver inputs the third gesture (second trajectory) 55 shown in FIG. 7B to the touch pad 310 again when it is determined that the input gesture does not exist (S22).

  When the determination unit 32 acquires an operation signal corresponding to the third gesture 55 based on a predetermined cycle from the input unit 31 via the control unit 30, the determination unit 32 performs the above-described determination process, and as an example, the left circle gesture 50 The degree of coincidence is calculated as 0.8, the degree of coincidence of the upper straight line gesture 51 is 0.2, and the degree of coincidence of the right straight line gesture 52 is calculated as 0.25.

  The determination unit 32 determines that the corresponding gesture is present because the determination threshold value is 0.7, and determines that the input gesture is the left circle gesture 50 (S23).

  The reference changing unit 33 determines, as the first condition, that the corresponding gesture is not present since it is determined that the corresponding gesture is present within a certain time (first time) after it is determined that the corresponding gesture is absent. 54 is considered to have input the left circle gesture 50, and the determination criterion of the left circle gesture 50 in the determination criterion information 352 of the driver is changed (S24; first change step).

As an example, the reference changing unit 33 calculates a new determination criterion by the following equation, where A is a determination threshold value and B is a calculated degree of coincidence.

  Since the reference change unit 33 has a determination threshold value of 0.7 and the calculated degree of coincidence is 0.6, if this is substituted into (Equation 1), the determination reference is calculated to be approximately 1.08.

  For example, when the determination criterion is 1.08, when the driver inputs the second gesture 54 shown in FIG. 7A to the touch pad 310, the determination value of the second gesture 54 is set to 0.6 × 1. .08 (approximately 0.65).

  Since the newly calculated determination value 0.65 is smaller than the determination threshold value 0.7, the second gesture 54 is not immediately determined to be the left circle gesture 50, but by repeatedly changing the determination criterion It is possible to suppress a decrease in determination accuracy based on individual differences when inputting information by gestures.

  The reference changing unit 33 changes the determination reference information 352 based on the calculated determination reference, stores it in the storage unit 35 via the control unit 30 (S25), and ends the process.

(About the judgment operation when the previous gesture is canceled)
FIG. 9A is a schematic diagram of the fourth gesture according to the embodiment of the present invention, and FIG. 9B is a schematic diagram of the fifth gesture. Hereinafter, a case where a gesture for canceling a gesture input to the touch pad 310 is input within a predetermined time will be described with reference to the flowchart shown in FIG. Portions overlapping with the above-described determination operation are described in a simplified manner.

  The driver inputs the fourth gesture 56 shown in FIG. 9A with the intention of inputting the left circle gesture 50 shown in FIG. 4A to the touch pad 310 (S30).

  As an example, the determination unit 32 calculates the degree of coincidence of the left circle gesture 50 as 0.4, the degree of coincidence of the upper straight line gesture 51 as 0.1, and the degree of coincidence of the right straight line gesture 52 as 0.75. Based on the determination threshold value 352, a right straight gesture (different trajectory) 52 is determined (S31; determination step, second result).

  The control unit 30 stores the information of the determined right straight gesture 52 in the storage unit 35 as history information 353 (S32), and changes the image displayed on the controlled device, that is, the display device 4 (S33).

  For example, the control unit 30 displays the hierarchy one level lower than the menu displayed on the display device 4.

  Since the image displayed on the display device 4 is different from the desired one, the driver cancels the control of the control unit 30 within a certain time (second time) as the second condition (third trajectory). ), That is, a left straight line gesture (a gesture from the right direction to the left direction) that returns to the next higher level is input (S34).

  After the determination unit 32 determines the left straight line gesture, the control unit 30 controls the display device 4 to return to the next higher level, and stores the left straight line gesture in the storage unit 35 (S35).

  The driver again inputs the fifth gesture (fourth locus) 57 shown in FIG. 9B intended for the left circle gesture 50 to the touch pad 310 (S36).

  When the determination unit 32 acquires the operation signal via the input unit 31 and the control unit 30, for example, the matching degree of the left circle gesture 50 is 0.75, the matching degree of the upper straight gesture 51 is 0.1, and the right straight line The degree of coincidence of the gesture 52 is calculated as 0.5, and the left circle gesture 50 is determined based on the determination threshold value of the determination reference information 352 (S37).

  Since the left straight line gesture stored in the storage unit 35 in step 35 is a gesture for canceling the right straight line gesture 52 stored in the storage unit 35 in step 32, the reference changing unit 33 is shown in FIG. Since the fourth gesture 56 is considered to have been input with the intention of the left circle gesture 50, the degree of coincidence 0.4 of the left circle gesture 50 in step 32 and the determination threshold value 0.7 are set as (Equation 1). And the criterion is changed to 1.38. Further, as an example, the reference changing unit 33 substitutes the degree of coincidence 0.75 of the right straight gesture 52 in Step 31 and the determination reference 0.7 into (Equation 1), and changes the determination reference to 0.97. (S38; second change step).

  The reference changing unit 33 changes the determination reference information 352 based on the calculated determination reference, stores it in the storage unit 35 via the control unit 30 (S39), and ends the process.

  In any of the cases described above, since the gesture is determined based on the degree of coincidence, the determination criterion is set higher and higher so that it is not determined that there is no corresponding gesture depending on the value of the determination criterion even if they completely match. A lower limit value may be provided.

  In the above-described example, the gesture operation is used as a control method for some controlled devices. However, the present invention is not limited to this, and it goes without saying that various modifications are possible.
