Hereinafter, a map display system according to an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram illustrating a configuration of a map display system 1 according to an embodiment. The map display system 1 includes a map display device 10 that displays a map, and an operation terminal 20 that receives an operation on a map displayed on the map display device 10. The map display system 1 can be applied to an application in which a map is displayed on a monitor of a navigation device in a navigation system in which a navigation device and a mobile terminal are connected by wireless communication. In this case, the navigation device corresponds to the map display device 10, and the mobile terminal corresponds to the operation terminal 20.

  The map display device 10 includes a monitor 11, a map change display unit 12, a map database (hereinafter referred to as “map DB”) 13, an operation content display unit 14, and a communication unit 15. The communication unit 15 has a function of communicating with the operation terminal 20. When the communication unit 15 detects the operation terminal 20, the communication unit 15 transmits map data including the area being displayed on the monitor 11 to the operation terminal 20. In addition, the communication unit 15 receives data indicating the operation content transmitted from the operation terminal 20. Note that the communication unit 15 can also transmit and receive data other than the above.

  The map change display unit 12 has a function of changing the map being displayed on the monitor 11 according to the operation content using the data of the map DB 13. For example, the map change display unit 12 scrolls the map or changes the scale of the map. The operation content display unit 14 has a function of displaying an image indicating the operation content superimposed on a map.

  The operation terminal 20 includes a touch panel 21, a memory 22, an operation content detection unit 23, and a communication unit 24. The communication unit 24 has a function of communicating with the map display device 10. The communication unit 24 receives, from the map display device 10, map data including an area being displayed on the map display device 10. In addition, the communication unit 24 transmits data indicating the operation content detected by the operation content detection unit 23 to the map display device 10. Note that the communication unit 24 can also transmit and receive data other than those described above.

  The touch panel 21 has a function of displaying a map being displayed on the map display device 10 and receiving a touch input. The touch panel 21 transmits touch input data to the operation content detection unit 23.

  The operation content detection unit 23 has a function of detecting the operation content based on the touch input data transmitted from the touch panel 21. For example, the operation content detection unit 23 detects the operation content of scale enlargement of the map from a touch input traced from two opposing directions toward a predetermined point on the touch panel 21 almost simultaneously. This touch input is detected by tracing the touch panel 21 so that the operator grasps a predetermined point. As another example, the operation content detection unit 23 detects the operation content of scrolling in the traced direction from a touch input tracing the touch panel 21. The operation content detection unit 23 transmits data indicating the detected operation content to the map display device 10 through the communication unit 24. In addition, the operation content detection unit 23 feeds back data indicating the detected operation content to the touch panel 21 and changes the map displayed on the touch panel 21 according to the operation content. Thereby, the map displayed on each of the touch panel 21 of the operation terminal 20 and the monitor 11 of the map display device 10 is linked.

  FIG. 2 is a diagram illustrating an operation of the map display system 1 according to the embodiment. When the map display device 10 detects the operation terminal 20, the map display device 10 transmits map data including the area being displayed to the operation terminal 20 (S10).

By transmitting map data in a wider range than the area being displayed, it is not necessary to transmit map data indicating a new area to the operation terminal 20 each time scrolling or changing the scale is performed. When the display of the map is changed, the data indicating the display range, for example, the coordinates of the center of the displayed area and the scale data are notified. Thereby, the data communication amount between the map display apparatus 10 and the operation terminal 20 can be reduced, and the interlocked map can be smoothly displayed.

  When receiving the map data transmitted from the map display device 10, the operation terminal 20 stores the received map data in the memory 22, and displays the same map as the map currently displayed on the map display device 10 on the touch panel 21. It is displayed (S12). Subsequently, the operation terminal 20 receives an operation input to the touch panel 21 (S14), and detects the received operation content (S16). The operation terminal 20 transmits data indicating the operation content detected by the operation content detection unit 23 to the map display device 10 (S18), and subsequently changes the map displayed on the touch panel 21 according to the operation content. (S20).
