The process defined in the icon is executed.

  FIG. 2 shows the configuration of the touch panel device 19 in one embodiment of the present invention. The touch panel device 19 includes a touch panel 21, a touch panel control unit 22, an optical position detection device 23, and an optical position detection device control unit 24. Further, as shown in the exploded view of the touch panel device 19 in the embodiment of the present invention in FIG. 3, the touch panel 21 is provided on the display screen of the display monitor 16, and the optical position detection device 23 is superimposed on the touch panel 21. Provide.

  As shown in FIG. 4, the touch panel 21 is of a transparent resistance film type, in which an ITO (Indium Tin Oxide) film 31 that is a kind of resistance film and an ITO film 32 are arranged opposite to each other via a spacer. Composed. Upper electrodes 41a and 41b are attached to both ends in the X-axis direction of the ITO film 31, and lower electrodes 42a and 42b are attached to both ends in the Y-axis direction of the ITO film 32, respectively. The ITO film 31 has a certain degree of elasticity. When pressure is applied to the upper surface of the ITO film 31, the portion where the pressure is applied bends and contacts the ITO film 32. Hereinafter, the ITO film-forming film 31 is referred to as a horizontal resistance film R1, and the ITO film-forming glass 32 is referred to as a vertical resistance film R2.

  The touch panel control unit 22 calculates a pressed position on the touch panel 21. The pressing position is calculated as follows. By applying a predetermined voltage to the upper electrodes 41a and 41b and detecting the voltage value of the lower electrodes 42a and 42b, the X coordinate of the pressed position is calculated, and the predetermined voltage is applied to the upper electrodes 42a and 42b. The Y coordinate of the pressed position is calculated by detecting the voltage value of the electrodes 41a and 41b.

  As shown in FIG. 3, the optical position detection device 23 has a frame shape, and the display screen of the display monitor 16 is observed through the rectangular opening 25. As shown in FIG. 5, the optical position detection device 23 includes a light emitting diode 51 and a photodiode 52, and the light emitting diode 51 and the photodiode 52 are disposed facing each other toward the inside of the rectangular opening 25. ing. The light emitting diode 51 emits infrared light, and the photodiode 52 detects the infrared light emitted by the light emitting diode 51.

  When the touch panel 21 is pressed with a finger or the like, the infrared light emitted from the light emitting diode 51 is shielded by the finger or the like, and the photodiode 52 disposed opposite to the light emitting diode 51 does not detect the infrared light. The optical position detection device control unit 24 calculates the pressed position from the position of the photodiode 52 that does not detect such infrared rays.

  The pressed position calculated in the touch panel control unit 22 and the optical position detection device control unit 24 is output to the control circuit 11.

  Next, with reference to FIG. 6, the principle of determining whether the driver's seat user has operated the touch panel device 19 or the passenger's seat user has operated the touch panel device 19 will be described. Reference numeral 61 denotes an infrared ray emitted from the light emitting diode 51, and a part thereof is shielded by a finger.

  In the case of a right-hand drive vehicle in which steering is provided on the right side with respect to the traveling direction of the vehicle, when the user at the driver's seat presses the touch panel device 19 with a finger, as shown in FIG. The finger extends and presses the touch panel device 19. At this time, when the coordinate system of the touch panel device 19 is the right direction of the X coordinate toward the paper surface, the X coordinate (X2) of the pressed position detected by the optical position detection device 23 is detected by the touch panel 21. The value is larger than the X coordinate (X1) of the pressed position. That is, the pressing position detected by the optical position detection device 23 is shifted to the driver's seat side compared to the pressing position detected on the touch panel 21. From this, it can be detected that the pressing direction of the touch panel device 19 is the driver seat direction, and it can be determined that the user of the driver seat has operated the touch panel device 19.

  On the other hand, when the user at the passenger seat presses the touch panel device 19 with his / her finger, as shown in FIG. 6B, the finger extends from the left direction from the paper surface and presses the touch panel device 19. At this time, when the right direction toward the paper surface is the positive direction of the X coordinate, the X coordinate (X2) of the pressed position detected by the optical position detection device 23 is the X coordinate (X1) of the pressed position detected by the touch panel 21. ) Will be smaller. That is, the pressing position detected by the optical position detection device 23 is shifted to the passenger seat side compared to the pressing position detected on the touch panel 21. From this, it can be detected that the pressing direction of the touch panel device 19 is the passenger seat direction, and it can be determined that the user of the passenger seat has operated the touch panel device 19.

  Next, a push button determination process for determining whether the button displayed on the display screen has been pressed by the driver seat user or the passenger seat user will be described with reference to FIGS. 7 and 8.

  FIG. 7 is a diagram for explaining a display screen displayed on the display monitor 16. A map 70 is displayed on the display screen. A self-vehicle position mark 71 is superimposed on the map 70.

Here, since the vehicle is running, it is assumed that the user at the driver's seat is prohibited from opening the menu screen.

  As shown in FIG. 7, when the menu button 72c is pressed, if the pressing direction is the driver's seat side, it is determined that the user at the driver's seat has operated, and the menu screen is not displayed even when the menu button 72c is pressed. . On the other hand, when the pressing direction is the passenger seat side, it is determined that the user of the passenger seat has operated, and a menu screen 73 is displayed on the display monitor 16 as shown in FIG. Here, the menu screen 73 includes a search button 74a for searching for a destination facility, a setting button 74b for performing various settings, a search button 74c for searching for a recommended route, and a traffic information button 74d for displaying traffic information.

  Next, referring to the flowchart of FIG. 9, for a button invalidation process that does not execute the process defined for the button even if the user at the driver's seat presses a button that is prohibited from being operated by the user at the driver's seat. I will explain. The process of FIG. 9 is performed by executing a program that starts when a button is displayed on the display screen in the control circuit 11.

  In step S901, it is determined whether the touch panel 21 of the touch panel device 19 is pressed. If it is pressed, an affirmative decision is made in step S901 and the process proceeds to step S902. If not, step S901 is repeated. In step S902, the pressed position of the touch panel 21 is calculated by the touch panel control unit 22, and the pressed position of the touch panel 21 is detected. In step S <b> 903, the pressed position of the touch panel 21 is detected by the optical position detection device 23.

  In step S904, the pressing position detected by the optical position detection device 23 and the pressing position detected by the touch panel 21 are compared to determine whether the pressing direction is the driver's seat side. In the case of the driver's seat side, an affirmative determination is made in step S904, and the process proceeds to step S905. If it is not on the driver's seat side, a negative determination is made in step S904, and the process proceeds to step S906. In step S905, the button 72c for which the operation of the driver's seat user is restricted is disabled. At this time, even if the button 72c is pressed, the processing defined for the button 72c is not executed. In step S906, the button 72c in which the operation of the driver's seat user is restricted is enabled. At this time, when the button 72c is pressed, the processing defined for the button 72c is executed.

The navigation device 1A according to the first embodiment described above has the following operational effects.
It can be determined which of the user in the driver seat and the passenger in the passenger seat has operated the touch panel device 19 from the pressing direction in which the touch panel 21 is pressed. Therefore, it is not necessary to hide the button 72c that restricts the operation of the driver's seat user.

The navigation device 1A of the above embodiment can be modified as follows.
(1) The optical position detection device 23 is not limited to the embodiment as long as it is optical. For example, an apparatus that detects light emitted to the retroreflective frame with an image sensor and detects a pressed position by a triangulation method may be used.

(2) The distance between the infrared ray radiated from the light emitting diode 51 of the optical position detection device 23 and the touch panel 21 is not particularly limited as long as the pressing direction can be detected. For example, it may be about the first joint (3 cm) of the finger.
