[2. Operation of input device]
Next, the operation of the input device according to the embodiment will be described with reference to FIGS.

(2.1 Operation example of input unit status setting)
First, an operation example of setting the state of the input unit will be described with reference to FIGS.
FIG. 4 is a schematic diagram illustrating an example of the state setting of the input unit by the user. FIG. 5 is a flowchart illustrating an example of an operation for setting the state of the input unit in the input device according to the first embodiment. FIG. 6 is a schematic diagram illustrating an example of how a user's finger touches the input unit. FIG. 7 is a schematic diagram illustrating an example of a locus touched by a user's finger.

  As shown in FIG. 4, in order to set the state of the input unit 11, the user sits in the driver's seat of the vehicle and holds the steering wheel unit 32. Then, the user places the left and right thumbs on the input unit 11. Specifically, the left thumb is applied to the input unit 11L, and the right thumb is applied to the input unit 11R. Then, the user traces the surfaces of the input units 11R and 11L with the thumb downward while holding the steering wheel unit 32.

  Next, as illustrated in FIG. 5, the input device 10 acquires contact position information in the input unit 11 (step S <b> 1). Specifically, as illustrated in FIG. 6, as an example of the position information acquisition unit, the system control unit 15 of the input device 10 includes the x coordinate of the portion traced by the user's finger 5 on the surface of the input unit 11 </ b> R, and The y coordinate position information (an example of position information related to the position where the user's finger reaches) is acquired from the input unit 11R. More specifically, as shown in FIG. 7, the system control unit 15 determines the position information of the x-coordinate and y-coordinate of the contact area C of the part in contact with the user's finger at a certain time (the user's finger reaches). An example of position information regarding the position is acquired from the input unit 11. Then, the system control unit 15 acquires the position information of the contact area C at a certain time interval, so that the position information of the x coordinate and the y coordinate of the trajectory T1 of the contact area C (position information on the position where the user's finger reaches) Example).

  Note that the system control unit 15 also acquires position information from the input unit 11L. Further, in the input portion 11R, the x-axis is a direction from the central portion of the steering body 31 toward the steering wheel portion 32 side. In the input portion 11L, the x-axis is a direction from the steering wheel portion 32 side toward the center portion of the steering body portion 31.

  As described above, the system control unit 15 of the input device 10 receives the user's finger from the input unit 11 that receives an input from the user in a state where the steering 30 as an example of an attachment target to which the input device 10 is attached is held by the user's hand. Functions as an example of position information acquisition means for acquiring position information related to the position where the message reaches from the input unit 11.

  Next, the input device 10 calculates a dividing line from the acquired position coordinates (step S2). Specifically, the system control unit 15 of the input device 10 calculates the dividing line D1 from the position information of the x coordinate and the y coordinate of the locus T1 of the contact area C as an example of the position information. For example, the system control unit 15 calculates a curve on the center side of the steering body 31 opposite to the steering wheel unit 32 side (an example of the side held by the user's hand in the input unit) in the trajectory T1 of the contact region C. The dividing line D1. At this time, the system control unit 15 calculates the dividing line D1 from the locus of the point having the minimum value of the x coordinate of the contact area C. That is, the dividing line D1 is set at a position away from the side held by the user's hand in the input unit 11R. The system control unit 15 calculates a dividing line from the input unit 11L from the locus of the point having the maximum x coordinate value of the contact area C.

  Here, a user with a short finger is more likely to have the division line D1 closer to the steering wheel unit 32 than a user with a long finger. Further, in the input unit 11R and the input unit 11L, the shape, position, etc. of the dividing line may be different.

  Next, the input device 10 sets the first part and the second part in the input unit 11 based on the dividing line (step S3). Specifically, the system control unit 15 of the input device 10 includes a steering wheel unit 32 side (outside of steering) on the side held by the user's hand from the dividing line D1 in the input unit 11R (outside of the steering wheel). Side example) is set to the first portion 11a, and the center portion side (inside the steering) of the steering body 31 is set to the second portion 11b. The input device 10 stores the position coordinates of the area of the first portion 11a and the position information of the area of the second portion 11b in the storage unit 13. Note that the input device 10 may store the coordinate information of the dividing line D1 in the storage unit 13.

  Thus, the system control unit 15 of the input device 10 functions as an example of a part setting unit that sets the first part 11a and the second part 11b in the input part 11 based on the position information. In addition, the system control unit 15 of the input device 10 functions as an example of a part setting unit that sets the first part 11 a to the side held by the user's hand in the input unit 11. The system control unit 15 of the input device 10 calculates a dividing line D1 that divides the input unit 11 into the first part 11a and the second part 11b based on the position information, and the input unit according to the dividing line D1. 11 functions as an example of a part setting means for setting the first part 11a and the second part 11b.

  Next, the input device 10 sets the states of the first part and the second part (step S4). Specifically, the system control unit 15 of the input device 10 sets the state of the first part 11 a to a state where no operation input to the operation target 20 is accepted, and changes the state of the second part 11 b to the operation target 20. Set to the state that accepts the operation input. For example, in the traveling state in which the vehicle has started traveling, the system control unit 15 sets the state of the first portion 11a to a state in which no operation input to the operation target 20 is accepted, and changes the state of the second portion 11b to the operation state. It sets to the state which receives the operation input to the object 20. Here, examples of the running state include a case where the speed of the vehicle is equal to or higher than a predetermined speed, a case where the gear is in a driving state, and the like.

  As described above, the system control unit 15 of the input device 10 sets the first part 11a to a state in which the operation input for operating the operation target 20 is not accepted, and sets the second part 11b to a state in which the operation input is accepted. It functions as an example of input unit state setting means to be set.

(2.2 Example of hold release operation)
Next, an operation example of releasing the hold state that blocks the operation input to the operation target 20 will be described with reference to FIGS. 8 and 9.
FIG. 8 is a flowchart illustrating an example of the hold release operation in the input device according to the first embodiment. FIG. 9 is a schematic diagram illustrating an example of display on the input device after the hold is released.

  When the system control unit 15 of the input device 10 acquires travel-related information via the communication unit 14 and determines that the vehicle is in a travel state, the input to the operation target 20 is prevented in order to prevent an operation unintended by the user. The states of the units 11R and 11L are set to a hold state in which an operation input to the operation target 20 is not accepted. The car navigation device 22 may be in a hold state where it does not accept direct operation input.

  As described above, the system control unit 15 of the input device 10 functions as an example of a hold state setting unit that sets the input unit 11 to a hold state that does not accept an operation input.

  And the system control part 15 sets the state of the 1st part 11a to the state which does not receive the operation input of cancellation | release of the hold state to the operation target 20, and the system control part 15 changes the state of the 2nd part 11b. The operation target 20 is set in a state of accepting an operation input for releasing the hold state.

  As described above, the system control unit 15 of the input device 10 sets the first part 11a to a state in which the hold state is not canceled even if an input is received from the first part 11a, and the second part 11b is set to the second part. When an input is received from 11b, it functions as an example of an input unit state setting means for setting the state to cancel the hold state.

  Next, as illustrated in FIG. 8, the input device 10 acquires contact position information in the input unit 11 (step S <b> 10). Specifically, the system control unit 15 of the input device 10 acquires the position information of the x coordinate and the y coordinate of each pixel in the contact area C of the portion where the user's finger of the input units 11R and 11L is in contact.

  Next, the input device 10 determines whether or not the contact position is the second portion (step S11). Specifically, the system control unit 15 of the input device 10 refers to the storage unit 13 and determines whether a part of the area of the contact area C is in the area of the second part 11b. For example, the system control unit 15 determines whether each pixel in the area of the contact area C of the input unit 11R is a pixel in the area of the second portion 11b.

  When the contact position is not the second part (step S11; NO), the input device 10 returns to the process of step S10.

  When the contact position is the second portion (step S11; YES), the input device 10 releases the hold state (step S12). Specifically, the system control unit 15 of the input device 10 releases the hold state of the input units 11R and 11L so that an operation input can be accepted. For example, as shown in FIG. 9, the system control unit 15 displays a screen for accepting an operation input on the screen of the input unit 11R. At this time, the input device 10 may transmit a signal for releasing the hold state of the car navigation device 22 via the communication unit 14 so as to release the hold state of the car navigation device 22. Further, the input device 10 may send a signal via the communication unit 14 so that the display as shown in FIG.

  When it is determined that the user's finger is in contact with the second portion 11b of the input unit 11R, the system control unit 15 does not cancel the hold state of the input unit 11L, and cancels the hold state of only the input unit 11R. May be.

  Next, the input device 10 receives an operation input (step S13). Specifically, the system control unit 15 of the input device 10 receives an operation input to the operation target 20 from the input units 11R and 11L. For example, as illustrated in FIG. 9, the input unit 11 </ b> R accepts an operation input for increasing or decreasing the temperature of the air conditioning based on the contacted position.

  When there is no contact with the input units 11R and 11L and there is no input from the input units 11R and 11L during the hold release state, for example, when no operation state without operation input continues for a certain period of time, system control is performed. The state of the unit 15 and the input units 11R and 11L is returned to the hold state.

  As described above, according to the operation according to the embodiment, in the input device 10 that has the input unit 11 that receives an input from the user and operates the operation target 20, an attachment target (for example, an attachment device to which the input device 10 is attached) In the state where the steering body 31) is held by the user's hand, the position information related to the position where the user's finger 5 reaches the input unit 11 is acquired from the input unit 11, and the input unit 11 is based on the acquired position information. The first portion 11a and the second portion 11b are set, the first portion 11a is set to a state in which no operation input for operating the operation target 20 is accepted, and the second portion 11b is in a state to accept the operation input. By setting the first portion 11a and the first portion 11a according to the user, the position where the user's finger 5 reaches the input unit 11 while being held by the user's hand is set as a reference. Since a portion 11b can be set, according to the user, the user can prevent the occurrence of unintended operation.

  Moreover, when setting the 1st part 11a to the side (for example, the steering wheel part 32 side) hold | maintained by the user's hand in the input part 11, operation object 20 of releasing a hold state from a user's finger | toe 5 etc. Since the second portion 11b that accepts an operation input for operating is set at a farther position, it is possible to further prevent an operation unintended by the user.

  Further, the input unit 11 is set to a hold state in which no operation input is received, the first portion 11a is set to a state in which the hold state is not canceled even if an input is received from the first portion 11a, and the second portion 11b is set to When an input is received from the second portion 11b, when the hold state is set to be released, a one-cushion operation of releasing the hold state is required, so that an operation unintended by the user can be further prevented.

  Further, based on the position information, a dividing line that divides the input part into the first part 11a and the second part 11b is calculated, and the first part 11a and the second part 11b are connected to the input part 11 according to the dividing line. In the case of setting, the movable region of the user's finger 5 holding the attachment target such as the steering wheel 30 can be detected, so that it is possible to further prevent an operation unintended by the user according to the user.

  When the input unit 11 of the input device 10 is attached to the steering 30 of the moving body, it is possible to further prevent an operation unintended by the user during the traveling of the moving body.

  Note that the operation input in step S13 may be accepted without the hold release process in step S12. For example, when receiving a phone call as an example of the operation target 20, when the phone rings and the user's finger touches the second portion 11b of the hold release area, the operation of step S13 is not performed without the hold release processing of step S12. As an input reception process, it may be possible to connect to a telephone line. Further, when a confirmation screen such as traffic jam information appears on the display unit 22a of the car navigation device 22 while traveling, the confirmation is performed as the operation input acceptance process in step S13 without the hold release process in step S12. The screen may disappear. Further, when the user's finger touches the second portion 11b of the hold release area, the set temperature of the air conditioner or the like may be raised or lowered without undergoing the hold release process.

(2.3 Modifications related to lane markings)
Next, modified examples related to the dividing line will be described with reference to FIGS. 10 to 18.

  As shown in FIG. 10, in the case of the contact trajectory T2 with respect to the input unit 11R, the system control unit 15 extrapolates a line on the steering body 31 central portion side of the trajectory T2 of the contact area C as an example of position information. The dividing line D2 may be calculated. The extrapolation line may be a straight line or a curve corresponding to the curvature of the trajectory T2. In the input unit 11R, the system control unit 15 sets the steering wheel portion 32 side of the lane marking D2 as the first portion 11a and the center portion side of the steering body 31 of the lane marking D2 as the second portion 11b.

  Moreover, as shown in FIG. 11, the dividing line may be a tangent line of two contact areas C as an example of position information. The user touches two places on the input unit 11 </ b> R, and the system control unit 15 stores the position information of the two contact areas C in the storage unit 13.

Further, as shown in FIG. 15, the dividing line may be elliptical like the dividing line D6.

  In addition, as shown in FIG. 16, a predetermined area may be set in the second portion 11b from a position at a predetermined distance from the contact area C where the user's finger 5 is in contact. The system control unit 15 sets the center of the second portion 11b from the contact area C in the direction of the center of the steering body 31 in the x-axis direction. Then, the system control unit 15 sets a dividing line D7 having a predetermined shape from the central portion, and sets the second portion 11b of the predetermined region from the central portion. The system control unit 15 sets other than the second portion 11b in the input unit 11R as the first portion 11a. Further, as shown in FIG. 17, the second portion 11b of the predetermined area may be a dividing line D8 having a shape recessed toward the contact area C side. In this case, since the 2nd part 11b is dented in the steering body part 31 center part side, generation | occurrence | production of operation which a user does not intend can be prevented more.

Next, a modified example of setting the lane marking will be described with reference to FIG.
FIG. 18 is a schematic diagram showing how the lane markings are set.
