The estimated arrival time 36 indicates the estimated arrival time to the destination when traveling along the route being guided.

The mode bar 40 is an area indicating buttons corresponding to commands related to map display and the like, and in this example, a menu button 40, a current location button 42, and a route button 43 are displayed. The menu button 40 is a button for displaying the main menu of this navigation application. The current location button 42 is a button for instructing display in the current location mode. The route button 43 is a button for newly setting or changing the route to the destination.

Now, in the display example of FIG. 3A, when the user touches the guide plate 20, the display of the display 110 shifts to the guide point mode shown in FIG. 3B. The guide point mode outlines a guide route including the current location and a specific guide point.

In the guide point mode, the guide plate 20, the partial route image 30X, and the mode bar 40 are displayed on the display 110. In the guide point mode, the guide plate 20 displays a left button 24 and a right button 25 in addition to the direction arrow 21, the distance 22 to the next guide point, and the name 23 of the next guide point. The left button 24 and the right button 25 are buttons for changing the guide points to be displayed to the front and rear guide points on the guide route. Specifically, when the user touches the left button 24, the guide point (intersection A) immediately before the currently displayed guide point (intersection B) is displayed. Further, when the user touches the right button 25, the guide point (C intersection) next to the currently displayed guide point (B intersection) is displayed. The left button 24 is not displayed when the previous guide point does not exist in the guide route, and the right button 25 is not displayed when the next guide point does not exist. Also, even if the guide plate 20 is flicked to the right instead of touching the left button 24, the previous guide point is displayed, and even if the guide plate 20 is flicked to the left instead of touching the right button 25, the next guide point is displayed. The guide point is displayed. Note that "flick" refers to an operation in which a finger touching the screen on the touch panel is slightly slid or swiftly swept.

Further, in the guide point mode, the list button 27a is displayed adjacent to the guide plate 20. The list button 27a is used to display a guide point list, which is a list of guide points, and the details thereof will be described later.

The partial route image 30X displays the guide route 31 and the current location mark 32 on the map in the same manner as the current location image 30, but by simultaneously displaying the specific guide point specified by the user and the current location mark 32. , Shows the route of the part from the current location to the guide point. Specifically, as shown in FIG. 3B, in the partial route image 30X, the map and the guide route 31 so that the guide point to be displayed comes to the central position, that is, the position of the cross mark 37. , The current location mark 32 is displayed. Further, in the partial route image 30X, the distance 38 from the current location to the guide point (intersection B) to be displayed is displayed.

Also in the partial route image 30X, the scale change buttons 33 and 34 and the scale bar 35 are displayed as in the current location image 30. Further, the display content of the mode bar 40 in the partial route image 30X is the same as that of the current location image 30.

FIG. 3C is an example in which the next guide point is displayed in the guide point mode. That is, in the display example of FIG. 3 (b), when the user touches the right button 25 or flicks the guide plate 20 to the left, the example of FIG. 3 (c) is displayed. By touching the right button 25 or flicking to the left, the C intersection, which is the next guide point of the B intersection, is selected as the display target. Therefore, in FIG. 3C, the direction arrow 21, the distance 22, and the name 23 for the C intersection are displayed in the guide plate 20, and the map so that the C intersection coincides with the cross mark 37 in the partial route image 30X. , Guidance route 31, and current location mark 32 are displayed. When a guide point far from the current location is selected as the display target, the mobile terminal 100 automatically changes the scale of the map so that the guide point and the current location mark 32 can be displayed on one screen.

In this way, by touching the left button 24 and the right button 25 in the guide plate 20 or flicking the guide plate 20 left and right, the user selects an arbitrary guide point and selects the guide plate 20 and the partial route image 30X. Can be displayed. In the guide point mode shown in FIGS. 3 (b) and 3 (c), when the user touches the current location button 42, the display screen returns to the current location mode shown in FIG. 3 (a).

Next, the display of the guide point list will be described. In this embodiment, the guide point list, which is a list of guide points on the guide route, can be displayed by the operation of the user. Specifically, on the guide point mode display screen shown in FIGS. 3 (b) and 3 (c), when the user touches the list button 27a or flicks the guide plate 20 downward, the guide point list is displayed.

FIG. 4A shows an example of a guide point list. FIG. 4A shows an example in which the number of guide points is 6, the number of guide points that can be displayed on one screen in the guide point list is 6, and all the guide points can be displayed on one screen. Is. As will be understood by comparing FIGS. 3 (b) and 3 (c) with FIG. 4 (a), the guide point list is displayed instead of the guide plate 20 and the partial route image 30X. The mode bar 40 is displayed even when the guide point list is displayed.

As shown in FIG. 4A, the guide point list is composed of guide point plates 60 showing information on a predetermined number of guide points. Each guide point plate 60 includes a direction arrow 61 indicating the direction of travel, a distance 62 from the previous guide point to the guide point (that is, a distance between the guide points) 62, and a name 63 of the guide points. .. The plurality of guide point plates 60 are arranged so that the guide point plate 60 of the guide point near the departure point is located on the upper side and the guide point plate 60 of the guide point close to the destination is located on the lower side.

When the user touches any of the guide point plates 60 while the guide point list is displayed as shown in FIG. 4A, the display of the guide point list ends, and the guide plate 20 and the partial route for the guide point are finished. Image 30X is displayed. For example, when the user touches the guide point plate 60 at the B intersection while the guide point list is displayed as shown in FIG. 4 (a), the display screen becomes as shown in FIG. 3 (b), and the user is at the C intersection. When the guide bar 60 is touched, the display screen becomes as shown in FIG. 3 (c).

Further, when the user flicks the guide point list upward in FIG. 4A, the display of the guide point list ends, and the display screen returns to the display of the guide plate 20 and the partial route image 30X. If the user flicks the guide point list up without touching any of the guide point plates 60 after the guide point list is displayed, the display screen returns to the state before the guide point list is displayed.

The number of guide points that can be displayed on one screen of the guide point list is predetermined (6 in this embodiment). When the number of guide points existing on the guide path is larger than the number of guide points that can be displayed on one screen, the upper button 64 and the lower button 65 are displayed as shown in FIG. 4 (b). When the user touches the upper button 64, the guide point list scrolls downward, and the guide point plate 60 of the guide point before the A intersection (closer to the departure point) is displayed. When the user touches the lower button 65, the guide point list scrolls upward, and the guide point plate 60 of the guide point after the F intersection (closer to the destination) is displayed. The user can scroll the guide point list upward by flicking the guide point list down instead of touching the up button 64, and flicks the guide point list up instead of touching the down button 65. Even so, you can scroll down the guide point list.

Further, when the number of guide points existing on the guide route is larger than the number of guide points that can be displayed on one screen, the list button 27b is displayed as shown in FIG. 4 (b). In this case, since the flick to the top of the guide point list is determined to be a scroll instruction of the guide point list, a list button 27b is separately prepared as a button for closing the guide point list. When the user touches the list button 27b, the display of the guide point list ends, and the display screen returns to the display of the guide plate 20 and the partial route image 30X as shown in FIGS. 3 (b) and 3 (c). When the user touches the list button 27b without touching any of the guide point plates 60 after the guide point list is displayed, the display screen returns to the state before the guide point list is displayed.

Next, the route display processing according to this embodiment will be described. FIG. 5 is a flowchart of the route display process. This process is realized by the control unit 17 of the mobile terminal 100 executing the program stored in the storage unit 13. As a premise, it is assumed that the guidance route to the destination has been determined and the route guidance is being executed.

The control unit 17 basically displays in the current location mode as shown in FIG. 3A during route guidance (step S10). The control unit 17 determines whether the mobile terminal 100 has arrived at the destination (step S11), and if the mobile terminal 100 has arrived at the destination (step S11: Yes), the process ends.

When the destination has not arrived (step S11: No), the control unit 17 monitors the touch input to the touch panel 120 and determines whether or not the user has touched the guide plate 20 (step S12). If the user has not touched the guide plate 20 (step S12: No), the process returns to step S10, and the display in the current location mode is continued.

On the other hand, when the user touches the guide plate 20 (step S12), the control unit 17 ends the display in the current location mode and starts the display in the guide point mode exemplified in FIGS. 3 (b) and 3 (c). (Step S13). Then, the control unit 17 determines whether or not the instruction to change the guide point to be displayed has been given (step S14). Specifically, the control unit 17 determines whether the user touches the left button 24 or the right button 25 or flicks the guide plate 20 to the left or right. If the instruction to change the guide point has not been given (step S14: No), the process proceeds to step S16.

On the other hand, when the instruction to change the guide point is given (step S14: Yes), the control unit 17 changes the guide point to be displayed (step S15). That is, the guide points designated by the above touch or flick operation are displayed in the guide point mode as shown in FIGS. 3 (b) and 3 (c).

Next, the control unit 17 determines whether or not the user has instructed to display the guide point list (step S16). Specifically, the control unit 17 determines whether or not the user touches the list button 27a or flicks the guide plate 20 downward. If the display of the guide point list is not instructed (step S16: No), the process proceeds to step S20.

When the display of the guide point list is instructed (step S16: Yes), the control unit 17 displays the guide point list as illustrated in FIGS. 4A and 4B (step S17). Next, the control unit 17 determines whether or not the user has selected one of the guide points or instructed the end of the guide point list (step S18). Specifically, the control unit 17 determines whether or not the user touches any of the guide point plates 60 in the guide point list or touches the list button 27b. When the user has not selected the guide point or instructed to end the guide point list (step S18: No), the process returns to step S17.

When the user selects a guide point or gives an instruction to end the guide point list (step S18: Yes), the control unit 17 ends the display of the guide point list, and the guide point selected at that time is shown in FIG. Display in the guide point mode as in (b) and (c) (step S19).

Next, the control unit 17 determines whether or not the user has given an instruction to end the guide point mode (step S20). Specifically, the control unit 17 determines whether or not the user has touched the current location button 42. If the user has not instructed the end of the guide point mode (step S20: No), the process returns to step S14, and the display in the guide point mode is continued. On the other hand, when the user gives an instruction to end the guide point mode (step S20: Yes), the process returns to step S10, and the control unit 27 displays in the current location mode.

As described above, in the present embodiment, the intersection name and the traveling direction of the next guidance point may be displayed at the time of route guidance, and the guidance point list which is a list of guidance points may be displayed according to the user's operation input. can. Therefore, the amount of information to be displayed on one screen can be reduced, and the display can be easily viewed even on a small screen.

[Modification example]
(Modification 1)
As shown in FIG. 4B, when the number of guide points is larger than the number of guide points that can be displayed on one screen of the guide point list, the guide point list can be scrolled by flicking up and down. .. Generally, when the user performs a flick operation, the length of scrolling the display screen is determined according to the strength and length of the input, and scrolling continues for a while due to inertia even after the user releases the finger from the screen. (This is called "scrolling by inertia"). Here, when a plurality of guide points to the destination include notable guide points (hereinafter referred to as "attention guide points"), the control unit 17 includes the attention guide points in the display range. You may want to stop scrolling in this state. That is, when the user flicks with a certain strength, if the attention guide point does not exist in the scroll display direction, the scroll is performed by the length corresponding to the strength, but if the attention guide point exists. Scrolling is forcibly stopped at the position of the attention guide point. This prevents scrolling due to inertia from passing the attention guide point and ensuring that the attention guide point is displayed on the guide point list.

At this time, the attention guide point may be displayed in a manner different from that of other guide points. For example, the color of the attention guide point may be changed or surrounded by a thick frame so that the guide point is emphasized more than other guide points. The "attention guide point" is a point that the user needs to check in particular, such as an intersection that is congested or an intersection that corresponds to an entrance to a toll road.

(Modification 2)
In the above embodiment, the mobile terminal 100 searches for a route to the destination, but instead, a server device connected via a network may perform the route search.

FIG. 6 shows a configuration example of the system according to the modified example. As shown in FIG. 6, the mobile terminal 100 is connected to the server device 200 via the network 150. Then, the mobile terminal 100 provides route guidance by receiving necessary information from the server device 200.

Specifically, the mobile terminal 100 transmits a destination specified by the user, a stop-by place, the current position of the mobile terminal 100, and the like to the server device 200. The server device 200 performs a route search based on this information, determines a guidance route including a guidance point, and transmits the information to the mobile terminal 100. The mobile terminal 100 provides route guidance according to the guidance route received from the server device 200.
