[Communications system]
Next, a communication system 100 to which the navigation device 1 described above is applied will be described with reference to FIG. FIG. 2 shows a schematic configuration of a communication system 100 to which the navigation device 1 is applied.

  The communication system 100 mainly includes a DSRC roadside device 91, a DSRC vehicle-mounted device 92, and the navigation device 1. FIG. 2 shows only the minimum components of the navigation device 1 when performing road-to-vehicle communication.

  The communication system 100 is a road-vehicle communication system that performs dedicated narrow area communication (DSRC) between the DSRC roadside device 91 and the DSRC on-vehicle device 92. The DSRC roadside unit 91 is installed in a road, a parking lot, a fast food restaurant, or the like, and is configured to be able to perform IP communication and non-IP communication. When performing IP communication, the DSRC roadside unit 91 accesses a www server (not shown) through, for example, Internet connection. The DSRC roadside device 91 transmits the acquired IP system information and non-IP system information to the DSRC in-vehicle device 92.

  The DSRC onboard unit 92 is mounted on the vehicle and receives the IP system information and the non-IP system information transmitted from the DSRC roadside unit 91. The DSRC in-vehicle device 92 has an IC card for authenticating personal information. The DSRC vehicle-mounted device 92 transmits the received IP system information and non-IP system information to the navigation device 1. Thus, the DSRC in-vehicle device 92 functions as an IP system information receiving unit and a non-IP system information receiving unit.

  The navigation device 1 mainly includes a system controller 20, a communication device 38, and a display unit 40. The communication device 38 receives the IP system information and the non-IP system information transmitted from the DSRC in-vehicle device 92 and outputs the IP system information and the non-IP system information to the system controller 20.

[IP information and non-IP information]
Next, non-IP system information and IP system information will be described in detail.

  The use of non-IP information for information that can be processed by a simple operation by a user is under study. Specifically, it can be considered that the non-IP system information is used when the user selects either affirmative (yes) or negative (no). In this case, on the non-IP screen, an image, a character, and the like are displayed as push type information, and an amount, a time, and the like are displayed as instruction information. In addition, “Yes” and “No” buttons are displayed for use by the user. For example, the use scene of non-IP system information includes fixed services such as parking lot settlement and settlement. For this reason, it can be said that non-IP information has the advantage of high visibility with a small amount of information, and the advantage that the operation is simple and the operation is simple. However, the non-IP system information basically cannot allow the user to freely select from a plurality of options.

  On the other hand, the use of IP-based information when a service side provides a lot of information to a user using a browser is being studied. Specifically, it is conceivable that the IP system information is used when a user can freely select from a plurality of options by providing a plurality of images and options. For example, a use site of IP information includes a shopping site that compares many products. For this reason, it can be said that IP-based information has the advantage of high selectivity for information. However, IP-based information tends to be time-consuming for operations such as scrolling, and it takes time for html and image processing.

  Here, an example of a non-IP screen and an IP screen will be described with reference to FIG. FIG. 3A shows an example of a non-IP screen. On this non-IP system screen, an image A1 showing a product, an image A2 showing the price of the product, and an image A3 used for user confirmation are displayed. The image A1 is an image corresponding to push type information, and the image A2 is an image corresponding to instruction information. In addition, the image A3 displays a button A3a indicating “Yes” for selecting “Yes” and a button A3b indicating “No” for selecting “No”. The non-IP screen is created by the non-IP control unit 20b and the navigation UI 20d in the system controller 20 of the navigation device 1.

  FIG. 3B shows an example of an IP screen. This IP screen is composed of a screen A5 generated by a browser (hereinafter referred to as “browser screen” where appropriate). A plurality of images, options, and the like are displayed on the browser screen A5. The IP screen is created by the IP control unit 20a and the browser 20c in the system controller 20 of the navigation device 1.

[Display control method]
Next, a display control method executed by the system controller 20 in the present embodiment will be described.

  In the present embodiment, the system controller 20 performs processing by using both IP system information and non-IP system information for one service. Specifically, the system controller 20 obtains information from the user by performing control to display one or both of the IP screen and the non-IP screen, and causing the user to operate the display screen. . The system controller 20 performs processing related to one service by using a combination of information input by the user operating the IP screen and information input by operating the non-IP screen. That is, the system controller 20 sequentially displays the IP screen and / or the non-IP screen, acquires information input by the user operating the display screen, and sequentially uses the acquired information. Complete processing for one service.

  Specifically, in the present embodiment, the system controller 20 considers the advantages of the IP system information and the non-IP system information as described above, and the IP system screen and the non-IP system according to the content of the information to be operated by the user. Control is performed to display either one or both of the screens. In this case, the system controller 20 displays at least a non-IP system screen in a situation where the user's operability should be prioritized, and displays at least an IP system screen in a situation where the information selectivity should be prioritized. . For example, the system controller 20 displays an IP screen when the user selects a product, and displays a non-IP screen when the user performs payment.

  Furthermore, in the present embodiment, the system controller 20 divides the display screen according to the contents of the received service, the user's operation, etc. and displays both the IP screen and the non-IP screen at the same time (hereinafter referred to as the following). The display screen is appropriately switched between the IP screen and the non-IP screen. For example, when the information used by the user is switched between the non-IP system information and the IP system information, the system controller 20 performs such divided display and display screen switching. Further, the system controller 20 performs split display when, for example, non-IP information and IP information are received simultaneously. As described above, the system controller 20 functions as a processing unit and a display control unit.

  According to the display control method described above, it is possible to perform processing efficiently by using IP system information and non-IP system information together. Specifically, it is possible to allow the user to perform processing efficiently by appropriately utilizing both the advantages such as simple operability of non-IP information and the high selectivity of IP information. . That is, when a simple determination is requested from the user, information can be displayed in an easy-to-understand manner using a non-IP screen, thereby allowing the user to perform a quick operation. On the other hand, when the user makes a complicated selection, the user can make an appropriate selection by displaying detailed information using the IP screen.

(Display screen example)
Next, an example of a display screen according to the above-described display control method will be described with reference to FIG. The display screen described below is displayed when, for example, a product is purchased at a drive-through of a fast food restaurant. The display screen is generated by the system controller 20 of the navigation device 1 and displayed on the display 44 of the display unit 40.

  FIG. 4A shows a screen B1 displayed when the DSRC in-vehicle device 92 or the navigation device 1 detects DSRC information. The screen B1 is a non-IP screen and is used for allowing the user to select whether or not to select a product using the Web. In such a situation, a non-IP system screen is used from the viewpoint of user operability in order to allow the user to select one of two options.

  Specifically, the screen B1 displays an image B1a that displays a message for allowing the user to select whether or not to select a product using the Web, and an image B1b that is used for user confirmation. In the image B1b, a button B1b1 indicating “Yes” for selecting affirmation and a button B1b2 indicating “No” for selecting No are displayed. When the navigation device 1 cannot use the Web, it is not possible to select a product using the Web.

  FIG. 4B shows a screen B2 that is displayed after the user selects to select a product on the Web using the screen B1. The screen B2 corresponds to a screen that is divided and displayed. Specifically, the screen B2 includes a screen B2a displayed by reducing the screen B1 (non-IP screen) shown in FIG. 4A to a half size in the horizontal direction of the screen (see arrow C1), The screen B2b is newly displayed in a display area other than the screen B2a. The newly displayed screen B2b is an IP system screen and is displayed to notify that Internet information has been received. Thus, the screen B2 is divided into one screen, and the screen B2a that is a non-IP screen and the screen B2b that is an IP screen are displayed at the same time. This screen B2 is displayed when the user sets the display setting of the navigation device 1 to split display. Since the user selects to select a product on the Web, basically, the user cannot operate the screen B2a that is a non-IP screen. That is, the screen B2a is not active.

  On the screen B2b, which is an IP system screen, an image B2b1 that displays a message for notifying that the Internet information has been received and for allowing the user to select whether or not to open the browser is displayed. In addition, on the screen B2b, a button B2b2 showing “Yes” for selecting affirmative for the selection, and a button B2b3 showing “No” for selecting negative for the selection, Is displayed. The notification that the Internet information has been received may be automatically activated by providing a predetermined setting.

  Note that the system controller 20 receives IP system information in advance when the non-IP system screen as shown in FIG. 4A is displayed, and performs processing on the IP system information behind the scenes. be able to. Thereby, it is possible to quickly process the IP system information.

  FIG. 4C shows a screen B3 displayed when the user selects a product on the Web after selecting that the browser is opened using the screen B2b. The screen B3 is also equivalent to the screen displayed in a divided manner, similarly to the screen B2. Specifically, the screen B3 is divided into one screen, and a screen B3a that is a non-IP screen and a screen B3b that is an IP screen are displayed at the same time. As described above, since the user selects the product on the Web, basically, the user cannot select the product by operating the non-IP system screen. Therefore, an image B3a1 showing a message for prompting the user to operate the browser screen is displayed on the screen B3a that is a non-IP screen. In addition, for the screen B2 displayed after the user selects to select a product on the Web, an image B3a showing such a message is displayed instead of the screen B2a shown in FIG. 4B. You may do it.

  The browser screen B3b1 is displayed on the screen B3b which is an IP system screen. The browser screen B3b1 displays a list of products (not shown), the price and number of products ordered by the user, the total price of these products, and the like. The browser screen B3b1 has a button B3b2 indicating “Yes” for selecting affirmation and a button indicating “No” for selecting negative in order to confirm the order contents of the product by the user. B3b3 is displayed. When the user presses the button B3b2 in which “Yes” is indicated, the order content of the product shown on the browser screen B3b1 is transmitted to the DSRC roadside device 91 via the DSRC onboard unit 92.

  FIG. 4D shows a screen B4 that is displayed after the order details of the product are transmitted by the user operating the browser screen B3b1. The screen B4 is a non-IP screen, and is displayed by automatically deleting the browser screen B3b1 when the order content of the product is transmitted. That is, when the order contents of a product are transmitted, the display screen is switched from the IP screen to the non-IP screen. Specifically, the screen B4 is used for allowing the user to select whether or not to settle by DSRC. In such a situation, a non-IP system screen is used from the viewpoint of user operability in order to allow the user to select one of two options.

  On the screen B4, an image B4a showing a message for allowing the user to select whether or not to settle by DSRC, an image B4b showing the total price of the ordered product, and an image B4c used for user confirmation Is displayed. In the image B4c, a button B4c1 indicating “Yes” for selecting “Yes” and a button B4c2 indicating “No” for selecting “No” are displayed. The details of the product ordered by the user may be displayed on the image B4a showing the message.

  When the user presses the button B4c1 indicating “Yes”, that is, when the user chooses to make a payment by DSRC, the payment is made with a card. On the other hand, when the user presses the button B4c2 in which “No” is indicated, that is, when the user selects not to settle by DSRC, payment is made in cash.

  By using the display screen as described above, the user can efficiently perform processing related to one service by seamlessly operating the IP screen and the non-IP screen. Specifically, by using the IP screen, the user can visually select many options and can make an appropriate selection. In addition, by using a non-IP screen, the user can make a payment with a simple operation, and can make a payment quickly.

  In the above example, when a non-IP screen is displayed, the non-IP screen and the IP screen are simultaneously displayed (divided display) by reducing the non-IP screen to a half size. Although shown, this is not a limitation. In another example, when an IP system screen is displayed, the IP system screen and the non-IP system screen may be simultaneously displayed (divided display) by reducing the IP system screen to a half size. In the above example, the display screen is switched from the IP screen to the non-IP screen. However, the display screen can be switched from the non-IP screen to the IP screen.

  Further, in the above, when the user selects to select a product on the Web, that is, when the user selects to operate the IP system screen, basically, the user cannot operate the non-IP system screen. Explained. However, even when the user selects to operate the IP screen, it is possible to change from the operation on the IP screen to the operation on the non-IP screen according to the user's intention. In this case, the content operated using the IP system screen is cancelled. Conversely, even when the user selects to operate the non-IP screen, it is possible to change from the operation on the non-IP screen to the operation on the IP screen according to the user's intention. In this case, the content operated using the non-IP system screen is cancelled.

  Next, switching from split display to full screen display will be described with reference to FIG. In this embodiment, the system controller 20 displays the screen operated by the user in full screen when the user operates one of the non-IP screen and the IP screen that are displayed in a divided manner. For example, the system controller 20 displays a full screen when the user touches a screen that is divided and displayed. Furthermore, when the user operates the screen displayed on the full screen in this way, the system controller 20 returns to the original divided display screen.

  FIG. 5 is a diagram for specifically explaining the full screen display. FIG. 5A shows a screen B2 similar to FIG. That is, the screen B2 is a screen in which a screen B2a that is a non-IP screen and a screen B2b that is an IP screen are displayed separately. FIG. 5B shows a screen D1 in which the IP screen is displayed on the full screen when the user touches the screen B2b which is the IP screen. On the screen D1, a button D1a for returning from the full screen display to the original divided display is displayed. FIG. 5C shows a screen D2 in which the non-IP screen is displayed on the full screen when the user touches the screen B2a that is a non-IP screen. On the screen D2, a button D2a for returning from the full screen display to the original divided display is displayed.

  By switching from split display to full screen display as described above, a screen that is easy to view for the user can be displayed appropriately.

  In the above description, when the IP screen and the non-IP screen are divided and displayed, the non-IP screen and the IP screen are each displayed in half the size of the display screen. However, the present invention is not limited to this. In addition, the size of the IP screen and the non-IP screen when the divided display is performed can be freely set. For example, when the information used by the user is switched between non-IP system information and IP system information, the size of the screen to be newly displayed out of the IP system screen and the non-IP system screen is displayed from the beginning. Such a divided display can be performed by making it larger than the size of the screen. As an example, a screen to be newly displayed can be displayed with a size of 3/4 of the display screen, and a screen currently displayed can be displayed with a size of 1/4 of the display screen.

  In addition, when the IP screen and the non-IP screen are divided and displayed, the display screen is not limited to being divided in the horizontal direction, and the display screen may be divided in the vertical direction.

  Furthermore, in the above, when the user operates one of the non-IP screen and the IP screen that are divided and displayed, an example in which the screen operated by the user is displayed in full screen is shown. There is no limitation. In another example, instead of performing such full screen display, the size of one screen operated by the user can be displayed larger than the size of the other screen not operated by the user.

(Display control flow)
Next, a display control flow in the present embodiment will be described with reference to FIG. This flow is repeatedly executed by the system controller 20.

  First, in step S101, the system controller 20 determines whether IP information or non-IP information has been interrupted. When the IP system information or the non-IP system information is interrupted (step S101; Yes), the process proceeds to step S102, and when the IP system information or the non-IP system information is not interrupted (step S101; No), the process is step S101. Return to.

  In step S102, the system controller 20 determines whether a screen corresponding to the IP system information or the non-IP system information has already been displayed. Hereinafter, such display is referred to as “existing display”. On the other hand, display using interrupted IP system information or non-IP system information is referred to as “interrupt display”.

  If there is an existing display (step S102; Yes), the process proceeds to step S104. On the other hand, when there is no existing display (step S102; No), the process proceeds to step S103. In step S103, the system controller 20 displays a screen corresponding to the IP system information or non-IP system information interrupted in step S101. That is, the system controller 20 displays either the IP screen or the non-IP screen alone. Then, the process ends.

  In step S104, the system controller 20 determines whether the types of the existing display and the interrupt display are different. Specifically, the system controller 20 determines whether or not the types of information (either IP system information or non-IP system information) used for the existing display and the interrupt display are different. When the types of the existing display and the interrupt display are different (step S104; Yes), the process proceeds to step S105. On the other hand, when the types of the existing display and the interrupt display are the same (step S104; No), the process proceeds to step S107. In step S107, the system controller 20 displays a screen in which the information related to the existing display is overwritten by the IP system information or non-IP system information interrupted in step S101. In this case, one of the IP screen and the non-IP screen is displayed. Then, the process ends.

  In step S105, the system controller 20 determines whether or not the display setting of the navigation device 1 is set to split display. When it is in the divided display setting state (step S105; Yes), the process proceeds to step S106. In step S106, the system controller 20 performs split display using interrupt display using the IP system information or non-IP system information interrupted in step S101 and the existing display (step S106). That is, the system controller 20 performs split display using an IP screen and a non-IP screen. Then, the process ends.

  On the other hand, when it is not in the divided display setting state (step S105; No), the process proceeds to step S107. In step S107, the system controller 20 displays a screen in which the information related to the existing display is overwritten by the IP system information or non-IP system information interrupted in step S101. In this case, the display screen is switched between the IP screen and the non-IP screen. Then, the process ends.

  According to the processing described above, appropriate display can be performed by comparing the types of the existing display and the interrupt display. Specifically, both the interrupt display and the existing display are appropriately displayed simultaneously by split display even when the existing display and the interrupt display are different, that is, when information different from the information used for the existing display is interrupted. Can be made.
