Claims (2)

An information processing device capable of displaying a map in either a first display mode or a second display mode, each having a different display area on the screen of the display device, The first display mode is a mode in which the map is displayed across the entire screen, and the second display mode is a mode in which an image output by an application program other than the application program that performs the display of the map is displayed across the entire screen, and at the same time, the map is displayed in a window on a part of the screen. At a minimum, the scale applied when displaying the map in the first display mode, the scale applied when displaying the map in the second display mode, and the size of the window which is the area where the map is displayed when displaying the map in the second display mode are changeable. A storage unit that stores, at least, the identification information of the first display mode and a first value which is a scale setting value applied when the map is displayed in the first display mode, set by the user, in association with each other, and stores, at least, the identification information of the second display mode and a second value which is a scale setting value applied when the map is displayed in the second display mode, set by the user, and size information which is a window size setting value applied when the map is displayed in the second display mode, set by the user, in association with each other. Based on the first operation performed by the user, the first display mode and the second display mode are switched, Based on the second operation performed by the user, the scale of the displayed map is changed, A control unit that performs the following: It has, When the second operation is performed while the map is being displayed in the first display mode, the control unit changes the first value stored in the storage unit in order to change the scale when displaying the map in the first display mode, and does not change the second value stored in the storage unit in order to not change the scale when displaying the map in the second display mode. The control unit, after the second operation is performed while the map is displayed in the first display mode, switches the map display mode from the first display mode to the second display mode. When the operation is performed, the second value stored in the memory unit is applied as the setting value for the map scale, and the size information stored in the memory unit is applied as the setting value for the window size, and the map is displayed in a window on a part of the screen. Information processing device.
Furthermore, the position of the window on the screen, which is applied when displaying the map in the second display mode, is changeable. The storage unit stores, in association with the identification information of the second display mode set by the user, the second value set by the user, the size information set by the user, and the position information which is the setting value of the window position applied when displaying the map in the second display mode, set by the user. If the first operation is performed to switch the map display mode from the first display mode to the second display mode after the second operation is performed while the map is being displayed in the first display mode, the control unit further applies the position information stored in the storage unit as the setting value for the window's position information, and displays the map in a window on a part of the screen. The information processing apparatus according to claim 1.

Description

This invention relates to an information processing device. In recent years, in-vehicle navigation systems capable of displaying various types of information have emerged. In this regard, for example, Patent Document 1 discloses an in-vehicle terminal capable of displaying multiple content items in a widget format. Patent No. 7044933 A schematic diagram of the in-vehicle device according to the first embodiment.An example of displaying a road map using the first display mode.An example of displaying a road map using the second display mode.An example of configuration data stored in the memory unit.An example of the screen when the display mode is switched.A flowchart of the processes performed by the in-vehicle device. In recent years, in-vehicle devices capable of displaying various types of content on their screens (typically navigation systems) have emerged. Conventional navigation systems primarily featured full-screen displays, with users switching between road map screens, television screens, audio screens, and other displays. However, in recent years, in-car devices have emerged that can display individual applications separately in windows, similar to smartphones and personal computers. With such devices, for example, a specific application can be kept resident on the screen using a floating window, while another application is displayed in the background. However, when displaying a road map within a window, there's a problem: the readability of the road map changes depending on the window size. For example, consider switching a road map from full-screen to windowed view. In this case, the map's display area decreases, potentially causing parts of the screen to be cut off before and after the switch. For example, consider a scenario where a road map is displayed full-screen at a scale of 1:10,000, and the window size shrinks to one-quarter of its original size after a switch. In this case, the area of the map visible to the vehicle's occupants also becomes one-quarter. In other words, three-quarters of the previously displayed map area is cut off. This can lead to a decrease in usability, such as losing track of the relative positions of the vehicle and the destination. To solve this problem, it is preferable to have separate map scales for each display mode, for example, "display the map at a scale of 1:10,000 in full-screen mode" and "display the map at a scale of 1:20,000 in windowed mode." The information processing device described herein solves this problem. An information processing device according to one aspect of this disclosure is an information processing device capable of displaying a map in either a first display mode or a second display mode, each having a different display area on the screen of the display device. Specifically, the system includes a control unit that, based on a first operation performed by the user, switches between the first display mode and the second display mode, and based on a second operation performed by the user, changes the scale of the displayed map, wherein the control unit changes the scale when displaying the map in the first display mode, but does not change the scale when displaying the map in the second display mode, if the second operation is performed while the map is being displayed in the first display mode. The display area of the map on the display device screen differs between the first and second display modes. For example, if the first display mode displays the map using the entire screen area (full-screen display), the second display mode can display the map using a portion of the screen area (window display). The control unit can switch between the first display mode and the second display mode at any time based on user operation (first operation). Furthermore, the control unit can accept an operation to change the map scale (second operation). However, if the scale settings are linked between the first and second display modes, the aforementioned problem of reduced readability may occur. For example, consider a case where the first display mode is a full-screen map display, and the second display mode is a windowed map display on a portion of the screen. In this case, if the user sets the scale to 1/10,000 in the first display mode, and then also sets the scale to 1/10,000 in the second display mode, it will not be possible to continuously display the same range before and after changing the display mode. Therefore, when a scale change operation is performed while the map is being displayed in the first display mode, the control unit changes only the scale used when displaying the map in the first display mode. That is, it separately maintains the scale setting corresponding to the first display mode and the scale setting corresponding to the second display mode, and when a scale change operation is performed, it changes only the scale setting corresponding to the current display mode. When switching from the first display mode to the sec
