FIG. 3 is a flowchart showing an example of a processing procedure performed by the navigation device 10 according to the present embodiment. Hereinafter, a processing procedure when the navigation device 10 displays a demonstration of the route guidance function will be described.

In step S101, the operation receiving unit 103 receives the input of the destination from the user. Further, the position acquisition unit 102 acquires the current position of the navigation device 10. Subsequently, the route search unit 104 sets the current location acquired by the position acquisition unit 102 as a departure place and searches for a route from the departure place to the destination. The point designated by the user on the map screen may be set as the departure point.

The display unit 105 displays the route searched by the route search unit 104 on the map screen. At this time, the display unit 105 may reduce or enlarge the map screen so that the entire route including the departure point and the destination is displayed in the map screen.

In step S102, the operation receiving unit 103 receives designation of any two arbitrary points on the route as a section for displaying a demonstration of the route guidance function. As will be described later, the operation receiving unit 103 may repeatedly receive designation of two points on the route on the enlarged and displayed map screen.

In step S103, the operation reception unit 103 receives an instruction to start the demonstration display from the user. For example, the operation receiving unit 103 may receive the start of the demonstration display by detecting that the demo running start button on the map screen is pressed.

In step S104, the demo display control unit 106 starts the demonstration display of the route guidance function from the point on the route closer to the departure point, out of the two points received by the operation receiving unit 103, and the destination on the route. The demonstration display of the route guidance function ends at a point near the side.

Here, the route displayed on the map screen may be enlarged or reduced according to a user operation, so that the user can easily specify a section of the entire route to be demonstrated.

FIG. 4 is a diagram for explaining a screen display example when performing a demonstration. Each screen shown in FIG. 4 is a map screen (navigation screen) displayed on the display of the navigation device 10. First, when the route search is completed, the route R from the origin NS to the destination NE is displayed on the map screen 201.

First, the operation reception unit 103 receives, from the user, designation of two points included in the route displayed on the map screen as a section for demonstrating the retrieved route. For example, it is assumed that the user has designated two points on the map screen 201, a point T1 and a point T2 on the route.

Here, the operation receiving unit 103 may recognize that the user has designated two points on the route when the two touched points satisfy a predetermined condition. The predetermined condition may be, for example, a case where the timing at which the point T1 is touched and the timing at which the point T2 is touched are within a predetermined time (for example, within 0.5 seconds). If the predetermined condition is not satisfied, it may be assumed that the user has performed another operation instead of designating the two points T1 and T2 on the route.

The operation receiving unit 103 may receive the designation of two points included in the route by the user tracing the route displayed on the map screen. For example, when the user touches the route and slides his/her finger along the route, the point touched on the route and the point released are recognized as two points on the route designated by the user. You may do it. At this time, the operation accepting unit 103 may determine that the user is tracing on the route when the mode is switched to a predetermined mode (for example, a mode for designating a section where the demonstration display is performed). It is possible to prevent the user from being determined to be tracing the route even though he/she wants to move the map screen up/down/left/right and impair the operational feeling.

Further, when the point specified on the map screen is not the point on the route and the distance on the map between the point and the route is less than or equal to the predetermined distance, the operation reception unit 103 determines that the point is the most A point on the near route may be regarded as a designated point on the route. As a result, the operation receiving unit 103 can estimate the point that is assumed to be designated by the user, even if the point at which the user touches the map screen is slightly off the route. If there are multiple points on the route that are closest to the designated point, the point on the departure side may be regarded as the designated point, or the point on the destination side may be regarded as the designated point. You may consider it as the designated point.

Subsequently, as shown on the map screen 202, the display unit 105 displays a map screen in which an area (area) including a route between two points designated by the user is enlarged. At this time, the display unit 105 may enlarge and display the map screen 202 so that the two points designated by the user are located at the edges of the map screen. Alternatively, the display unit 105 may display the map screen 202 in an enlarged manner so that the two points designated by the user are located inside a predetermined distance from the edge of the map screen. For example, when the user specifies two points T1 and T2 on the map screen 201, the map screen 202 in which the range of the area A1 with the point T1 as the upper end and the point T2 as the right end is enlarged is displayed. You can In the example of the map screen 202, the points SS1 and SE1 correspond to the points T1 and T2 designated by the user on the map screen 201, respectively.

Further, when the operation reception unit 103 recognizes that the user has designated two points (point T3 and point T4) on the enlarged map screen 202, the display unit 105 displays the map screen 203 as shown in FIG. , The area including the route between the two points is enlarged and displayed. Also in this case, when the user designates two points T3 and T4 on the map screen 202, the map screen 203 in which the range of the area A2 including the point T3 at the upper end and the point T2 at the right end is enlarged is displayed. You may do so. In the example of the map screen 203, the points SS2 and SE2 correspond to the points T3 and T3 designated by the user on the map screen 201, respectively.

That is, when the operation reception unit 103 receives the input of two points, the display unit 105 may repeatedly perform the process of enlarging and displaying the area including the two points. Further, when the region including the two points is enlarged and displayed, the map screen may be enlarged so that the two points are located at the ends of the map screen or inside the predetermined distance from the ends. As a result, the user can quickly enlarge the screen, and thus can easily specify the section in which the demonstration is performed.

The method of enlarging and displaying the map screen is not limited to the above method. For example, if the user performs a pinch-out operation on the map screen (touching two points on the map screen and moving a finger to increase the distance between the two points), the map screen is enlarged and displayed. May be. When the user performs a pinch-in operation on the map screen (touching two points on the map screen and moving a finger to narrow the distance between the two points), the map screen is displayed in a reduced size. Good.

Subsequently, when the user presses the demo travel start button B1 on the map screen, the demo display control unit 106 causes the demo display control unit 106 to display the section (in the example of FIG. 4, in the example of FIG. 4) instructed by the user when the demo travel start button B1 was pressed. , The section from the point SS2 to the point SE2) starts the demonstration display. That is, when the operation reception unit 103 receives an instruction to start the demonstration display, the demo display control unit 106 displays the demonstration display for the section divided by the two points on the route that the operation reception unit 103 finally received. May be performed.

If the map screen is enlarged or reduced by performing pinch-out and pinch-in operations on the map screen, and if the user does not accept the designation of two points on the route, the user can select two points on the route. The demo running start button B1 may be grayed out until the designation is accepted.

When the demo drive button B1 is pressed on the map screen 203, the demonstration display is executed by moving the vehicle C icon from the point SS2 along the route R as shown in the map screen 204, for example. Further, in the demonstration display, not only the vehicle C icon may move along the route R, but driving guide display and the like may be performed by enlarging the road as shown on the right side of the map screen 203.

In addition, when the demo display control unit 106 receives an instruction from the user to start the demonstration display, the demo display control unit 106 estimates the time required from the start of the display of the demonstration to the end, and the estimated time is equal to or longer than the predetermined time. In some cases, the user may be prompted to select whether or not to start the demonstration display. With this, when the time required for the demonstration is long, the user can start the demonstration by further narrowing down the section for the demonstration instead of starting the demonstration, and thus the demonstration display can be performed more efficiently. It will be possible.

According to the embodiment described above, the navigation device 10 receives the designation of the section in which the demonstration display is performed from the user, and performs the demonstration display in the received section. This made it possible to set the section for the demonstration more flexibly. Further, according to this embodiment, the process of enlarging and displaying the route including the two points designated by the user on the map screen is repeatedly performed. As a result, even when the actual distance of the route from the departure place to the destination is long, the user can easily specify the section for which the demonstration display is desired.

The embodiments described above are for facilitating the understanding of the present invention and are not for limiting the interpretation of the present invention. The flowcharts and sequences described in the embodiments, the elements included in the embodiments, and their arrangement, materials, conditions, shapes, sizes, and the like are not limited to those illustrated, and can be changed as appropriate. Further, the configurations shown in different embodiments can be partially replaced or combined.
