  FIG. 3 is a diagram illustrating a personal computer 200 that is a simulation apparatus, a printer 201 that is a printing apparatus, and an example of a QR code that is printed by the printer 201.

  The personal computer 200 includes a display 202 corresponding to the second display device. Simulation software for simulating the operation of the in-vehicle navigation device 100 is installed in the personal computer 200. The simulation software is software that can display on the display 202 of the personal computer 200 a simulated screen that is the same as the screen of the display device 11 of the in-vehicle navigation device 100. This software is used by the second display device control means. Equivalent to.

  A touch switch displayed on the display device 11 of the in-vehicle navigation device 100 is also displayed on the simulation screen. When the switch displayed on the simulation screen is clicked with a mouse, the simulation software displays the touch switch of the in-vehicle navigation device 100. Similar to the display device 11, it is programmed to switch the simulation screen.

  Furthermore, the simulation software is programmed so that characters can be input to the simulation screen using a keyboard when the simulation screen is a character input screen, such as a destination input screen. When a predetermined code creation operation is performed from the keyboard or mouse, a QR code corresponding to the simulated screen displayed on the display 202 is created at that time, and the created QR code is output to the printer 201. The

  The printer 201 is connected to the personal computer 200 with a cable 203 and prints the QR code output from the personal computer 200.

  Next, processing until the QR code is printed will be described with reference to the flowchart of FIG. Note that the flowchart in the figure starts when an application that simulates the operation of the in-vehicle navigation device 100 is started by the user.

  In step S <b> 100, a simulated screen that is the same screen as the display device 11 of the in-vehicle navigation device 100 is displayed on the display 202 of the personal computer 200. When the switch displayed on the simulation screen is clicked with the mouse, the simulation screen is sequentially switched. By this mouse operation, the user switches the simulated screen to the screen intended by the user.

  In step S101, it is determined whether the simulation operation by the user is completed. Specifically, as shown in FIG. 5, an operation completion button 210 is displayed in the corner of the display 202, and the operation is completed depending on whether or not the operation completion button 210 is clicked by the user's mouse operation. It is determined whether or not. FIG. 5 shows a screen for selecting a home as a destination and starting route guidance.

  If it is determined in step S101 that the operation has not been completed, a negative determination is made, the process returns to step S100, and the simulation of the operation of the in-vehicle navigation device 100 is continued. On the other hand, if it is determined that the operation has been completed, an affirmative determination is made, and the process proceeds to step S102.

  In step S102, it is determined whether or not a QR code corresponding to the simulated screen displayed on the display 202 is created and printed. Specifically, as shown in FIG. 6, a pop-up window 501 indicating whether or not to print a QR code is displayed on the display 202. In this window 501, in addition to the inquiry message “Do you want to print the QR code” to the user, “Yes”, “No”, and “Cancel” instructing to re-simulate the operation of the in-vehicle navigation device 100 Is displayed.

  If it is determined that the QR code is to be printed, an affirmative determination is made, and the process proceeds to step S103, where a QR code is created and an instruction signal for printing the QR code is transmitted to the printer 201. In response to the instruction signal, the printer 201 prints out the QR code. Thereafter, the simulation software is terminated. On the other hand, if it is determined not to print the QR code, a negative determination is made, and the simulation software is terminated without outputting an instruction signal instructing printing of the QR code. Moreover, when it determines with performing the simulation of operation | movement of the vehicle-mounted navigation apparatus 100 again, a process is returned to step S100.

  Note that when creating a QR code related to route guidance, a QR code that automatically starts route guidance may be created without the user operating a guidance start switch for starting route guidance. For example, as shown in FIG. 6, a check button 502 for automatically starting route guidance is displayed, and when the check button 502 is clicked by a user's mouse operation, a QR code for automatically starting route guidance is created. .

  Next, processing in which the mobile phone 300 reads the QR code created by the personal computer 200 will be described with reference to the flowchart of FIG. The control circuit 42 performs the processing shown in FIG. Also, the process shown in the figure is started when an application for reading a QR code is started by the user.

  In step S400, the camera 41 is activated. As a result, an image projected by the camera 41 is displayed on the display device 38.

  In step S401, it is determined whether to read the QR code. Specifically, as shown in FIG. 8, first, a reading button 70 for instructing reading of a QR code is displayed on the display device 38, and the QR 71 is determined depending on whether or not the switch 71 corresponding to the reading button 70 is operated. Determine whether to read the code. A user who wants to read the QR code operates the switch 71 after the camera 41 is pointed at the QR code printed in advance and the QR code is displayed on the display device 38.

  If it is determined that the QR code is not read, a negative determination is made, and the process returns to step S400. On the other hand, if it is determined that the QR code is read, an affirmative determination is made, and the process proceeds to step S402.

  In step S402, it is determined whether or not the read QR code is transmitted to the in-vehicle navigation device 100. Specifically, a message or a graphic for inquiring whether or not to transmit the QR code to the in-vehicle navigation device 100 is displayed on the display device 38, and then either an operation for instructing transmission or an operation for instructing not to transmit is displayed. Whether or not to transmit the read QR code to the in-vehicle navigation device 100 is determined depending on whether or not is performed.

  If it is determined that the read QR code is not transmitted to the vehicle-mounted navigation device 100, a negative determination is made and the process exits this flowchart. On the other hand, when it determines with transmitting, affirmation determination is carried out, In step S403, QR code is transmitted to the vehicle-mounted navigation apparatus 100 using the BT communication apparatus 30, Then, this flowchart is exited. Since the QR code is transmitted to the in-vehicle navigation device 100 using the BT communication device 30 as described above, the QR code printed by the printer 201 is prepared in the vehicle interior, and the processing of FIG. 7 is performed in the vehicle interior. Need to run.

  The above-described inquiry message or figure can be instructed to reread the QR code. If it is determined that the QR code is to be read again based on the instruction (cancellation), the process returns to step S400. .

  FIG. 9 is a flowchart showing the processing of the in-vehicle navigation device 100 when acquiring the QR code from the mobile phone 300. This process is performed by the control circuit 9.

  In step S500, it is determined whether the BT communication apparatus 17 has received a QR code. This process is repeated until a QR code is received (No determination at step S500). On the other hand, if a QR code is received, the process proceeds to step S501.

  In subsequent step S501, the content of the received QR code is decoded. Next, in step S502, the screen of the display device 11 is switched to a screen corresponding to the QR code based on the result decoded in step S501. Thus, for example, as shown in FIG. 10, the home is switched to the guidance start screen set as the destination, as shown in FIG. 11, the screen is switched to a screen in the middle of inputting the destination, as shown in FIG. In this way, the screen is switched to the screen after the route from the departure point to the destination is set. In addition, after the process of step S502 is complete | finished, a process is returned to step S500.

  As described above, in the present embodiment, a simulation screen that is the same screen as the screen displayed on the display device 11 of the navigation device 100 can be displayed on the display 202 of the personal computer 200. QR code corresponding to can be printed. Accordingly, the screen of the display device 11 that has to be subjected to troublesome operations several times or more can be displayed on the personal computer 200, and the QR code corresponding to the screen can be printed and prepared by the printer 201. .

  If the QR code is prepared in such a manner, the QR code prepared by the camera 41 of the mobile phone 300 is read thereafter, and the QR code read by the camera 41 of the mobile phone 300 is read by the BT communication device 17. If acquired, the screen corresponding to the QR code acquired by the BT communication device 17 is displayed on the display device 11, so that the operation burden on the user for displaying the intended screen on the display device 11 is reduced.

  In this embodiment, since the mobile phone 300 including the camera 41 is used as the mobile communication device, and the QR code is read by the camera 41 of the mobile phone 300, the in-vehicle navigation device 100 reads the QR code. It is not necessary to provide the device.

  In addition, this invention is not limited to this embodiment, Based on the meaning of this invention, it can implement with a various form.

  For example, in the above-described embodiment, the mobile phone 300 is used to read the QR code into the in-vehicle navigation device 100. However, the in-vehicle navigation device 100 may be connected to a QR code reader that can read the QR code.

  In the above-described embodiment, the screen corresponding to the QR code read by the camera 41 is not displayed on the display device 38 of the mobile phone 300, but the camera 41 is read by the control circuit 42 of the mobile phone 300. A function for causing the display device 38 to display a screen corresponding to the QR code may be added. FIG. 13 is a diagram illustrating an example in which a screen corresponding to the QR code read by the camera 41 is displayed on the display device 38 of the mobile phone 300. In this way, if the screen corresponding to the QR code is also displayed on the display device 38 of the mobile phone 300, it is confirmed whether the QR code transmitted to the in-vehicle navigation device 100 is a QR code corresponding to the intended screen. can do.

  Further, when the screen corresponding to the QR code is a screen in the middle of setting the destination, the user needs to operate the in-vehicle navigation device 100 and input the final destination. At this time, the destination may be input from the mobile phone 300. In this case, the destination may be input by operating the push switch of the mobile phone 300, or the destination may be input by the user's voice. FIG. 14 is a diagram showing the cellular phone 300 at this time, and the display device 38 displays characters (“showa”) input from the push switch. In addition, what is necessary is just to operate the transfer switch 72, in order to transfer the character input with the push switch to the vehicle-mounted navigation apparatus 100. FIG. Further, when inputting the destination by the user's voice, the voice is input from the voice input device 40 after the voice recognition switch 73 is operated.

  FIG. 15 is a diagram showing a screen displayed on the display device 11 of the in-vehicle navigation device 100 when the transfer switch 72 is operated in the state of FIG. Has been. When the voice recognition switch 73 is operated, the graphic 23 indicating the voice recognition mode is displayed on the screen of the display device 11 (see FIG. 15).

  The example in which the destination at the time of route search is input by the mobile phone 300 has been described above, but other operations of the in-vehicle navigation device 100 may be operated by the mobile phone 300.
