Abstract

A temporary route from a current point of a mobile object acquired by an acquisition unit (102) to a destination point via a designation input point for which a designation input is performed by an input unit (104) is retrieved by a retrieval unit (105) while the execution of route guidance processing using a guidance route to the destination point by a route guidance unit (107) is continued. A display unit (101) is controlled by a display control unit (108) to display information on the temporary route while the destination input is continued and erase the information on the temporary information when the designation input is canceled or the designation input is continued for a predetermined period of time or longer. When a confirmation unit (106) confirms during the display of the temporary route that route guidance is executed by using the temporary route instead of the guidance route, the route guidance unit (107) changes the guidance route to the temporary route and executes the route guidance processing.

Hereinafter, preferred embodiments of an information display device, an information display method, an information display program, and a recording medium according to the present invention will be described in detail with reference to the accompanying drawings.

(Embodiment)
(Functional configuration of information display device)
First, the functional configuration of the information display apparatus 100 according to the embodiment of the present invention will be described. FIG. 1 is a block diagram showing a functional configuration of the information display apparatus according to the present embodiment.

In FIG. 1, an information display device 100 includes a display unit 101, an acquisition unit 102, a scroll unit 103, an input unit 104, a search unit 105, a confirmation unit 106, a route guidance unit 107, and a display control unit 108. And. The display unit 101 includes a display screen that displays map information. Here, the map information is stored in a storage unit (not shown). The map information includes road network data composed of nodes and links, and image data drawn using features relating to facilities, roads, and other terrain (mountains, rivers, land). The map information may include character information, information such as facility names and addresses, road and facility images, and the like.

The acquisition unit 102 acquires position information of the current location of the moving object. Specifically, the position information of the current location of the mobile object is acquired by, for example, a GPS unit or an acceleration sensor provided in the mobile object.

Scroll unit 103 scrolls the map information displayed on display unit 101. The scroll part 103 changes the range of the map information currently displayed on the display part 101 gradually according to the input of a user's operation. Note that a point mark may be superimposed and displayed at the center point of the scroll, that is, the center point of the map information displayed on the display unit 101.

The input unit 104 receives a designation input of a point on the map information displayed on the display unit 101. Further, the input unit 104 may accept a designation input in which the scroll end point by the scroll unit 103 is designated as a point where the designation input is made (hereinafter referred to as “designated input point”). The scroll end point is, for example, the center point of scrolling when a predetermined time has elapsed since stopping scrolling of map information, that is, the center point of map information displayed on the display unit 101. Further, the input unit 104 may accept a designation input using any point on the map information selected by the user other than the scroll end point as a designated input point.

The search unit 105 searches for a route (hereinafter referred to as “temporary route”) from the current location of the moving object to the destination location via the designated input location. For example, when the input unit 104 receives a designation input in which the scroll end point by the scroll unit 103 is designated as the designated input point, the search unit 105 receives the mobile object via the center point of the map displayed on the display unit 101. Search for a temporary route from the current location to the destination location. Note that the search unit 105 may search for a temporary route in consideration of traffic restrictions such as one-way traffic and right / left turn prohibition and traffic jam information. In this way, a route that does not include a narrow street that is difficult to pass by one way or a road that is congested can be searched for a route that the user can move efficiently.

In addition, when the position information of the current location of the moving object acquired by the acquisition unit 102 is changed while the temporary route is being displayed, the search unit 105 temporarily changes the current location of the changed moving object to the designated input point. The route may be re-searched. That is, the search unit 105 may update the temporary route according to the change in the position information of the current location of the moving object acquired by the acquisition unit 102.

The confirmation unit 106 confirms whether or not to perform route guidance using the temporary route instead of the guidance route to the destination while displaying the temporary route. Specifically, for example, the display unit 101 displays, for example, a key for accepting selection from the user as to whether to perform route guidance using a temporary route instead of the guidance route, and detects which key is pressed. Thus, it is confirmed whether or not the route guidance is executed using the temporary route instead of the guidance route.

The route guidance unit 107 executes route guidance processing using the guidance route to the destination point. In addition, when the confirmation unit 106 confirms that the route guidance process is performed using the temporary route instead of the guidance route, the route guidance unit 107 changes the guidance route to the temporary route and performs the route guidance process. Execute. Note that the route guidance unit 107 may continue to perform route guidance processing using the guidance route while displaying the temporary route.

The display control unit 108 controls the display unit 101 to display information about the temporary route while the designated input is continued. When the designated input is canceled or when the designated input is continued for a predetermined time or longer, the display control unit 108 controls the temporary route. Clear the information display. Here, the information on the temporary route is, for example, the route from the current point to the destination point via the designated input point, the information on the movement distance to the destination point in that case, and the information on the estimated arrival time at the destination point. The display control unit 108 may control the display unit 101 to display only the information on the travel distance and the estimated arrival time without displaying the route from the current point to the destination point via the designated input point.

Further, the display control unit 108 controls the display unit 101 to display the information related to the temporary route and the information related to the guidance route in a display form that can be compared while the designated input is continued. Specifically, the display control unit 108 displays, for example, information on the temporary route and information on the guidance route in different colors and different line types. Further, the display control unit 108 may display the difference between the information related to the temporary route and the information related to the guidance route. Specifically, for example, the difference between the travel time and the estimated arrival time that are changed by changing from the guidance route to the temporary route such as “+2 km” or “−30 minutes” may be displayed.

(Information display processing procedure of information display device)
Next, an information display processing procedure of the information display device 100 will be described. FIG. 2 is a flowchart showing an information display processing procedure of the information display device. In the flowchart of FIG. 2, first, route guidance processing is performed by the route guidance unit 107 using the guidance route to the destination point (step S201). By executing the route guidance process in step S201, information on the guidance route is displayed on the display unit 101. Further, the position information of the current location of the moving object is acquired by the acquisition unit 102 (step S202). Furthermore, it waits until the input designation | designated of the point on map information is received by the input part 104 (step S203: No loop).

Next, when a designated input is received in step S203 (step S203: Yes), the search unit 105 passes the designated input point accepted in step S203 and starts from the current location of the moving object obtained in step S201. A route to the destination point, that is, a temporary route passing through the designated input point is searched (step S204). In step S204, a temporary route may be searched in consideration of traffic regulation and traffic jam information.

Next, the display control unit 108 controls the display unit 101 to display information on the temporary route (step S205). In step S205, the information on the temporary route is displayed in a display form that can be compared with the information on the guidance route. Then, it is determined whether or not the designated input has been canceled or whether or not the designated input has been continued for a predetermined time (step S206). In step S206, when the designated input is canceled or the designated input is continued for a predetermined time or longer (step S206: Yes), the display of the information on the temporary route is deleted (step S207), and the series of processes is ended. .

On the other hand, if the designated input is not canceled or the designated input has not been continued for a predetermined time or longer in step S206 (step S206: No), the confirmation unit 106 executes route guidance processing using a temporary route instead of the guidance route. It is confirmed whether or not to perform (step S208). In step S208, when it is not confirmed that the route guidance process is executed using the temporary route instead of the guidance route (step S208: No), the process returns to step S206, and the subsequent processing is repeated. In step S208, when it is confirmed that the route guidance process is executed using the temporary route instead of the guidance route (step S208: Yes), the route guidance unit 107 changes the guidance route to the temporary route. A route guidance process is executed (step S209), and the series of processes ends.

In the flowchart of FIG. 2, the route guidance processing using the guidance route to the destination point executed in step S201 is continued until the guidance route is changed to a temporary route and the route guidance processing is executed in step S209. Suppose that That is, in the flowchart of FIG. 2, information on the temporary route from the current location of the moving object to the destination location is displayed via the designated input location while continuing the route guidance processing using the guidance route to the destination location. .

In the flowchart of FIG. 2, it may be determined in step S203 whether or not the end point of scrolling by the scroll unit 103 that scrolls the map information displayed on the display unit 101 is accepted as the designated input point.

In the flowchart of FIG. 2, the scale of the map information may be changed so that all the differences between the temporary route and the guidance route are displayed when displaying information about the temporary route in step S205. That is, all the nodes and links that are changed from the guidance route to the destination point may be displayed by way of the designated input point. In this way, for example, a point that branches from the guide route to the temporary route from the current point of the moving object to the destination point is displayed, but the point where the temporary route joins the guide route is not displayed. Can do. As a result, the user can confirm all the differences between the guide route and the temporary route, and therefore can determine whether or not to change the guide route to the temporary route.

In the flowchart of FIG. 2, after displaying the information about the temporary route in step S205, the display of the information about the temporary route is deleted in step S207, or the guidance route is changed to the temporary route in step S209. Until the execution of, the position information of the current location of the moving body may be continuously acquired, and the temporary route may be updated according to the change in the position information of the current location of the moving body.

In the flowchart of FIG. 2, it is determined in step S206 whether or not the designated input has been canceled or whether or not information related to the temporary route has been displayed for a predetermined time or more. However, the present invention is not limited to this. Specifically, it may be determined only whether the designated input is released. In this case, regardless of whether or not the information about the temporary route is displayed for a predetermined time or longer, the process proceeds to step S208 if the designated input is not released, and the process proceeds to step S207 if the designated input is released.

As described above, according to the information display device 100 of the present embodiment, the route guidance unit 107 performs the route guidance process using the guidance route to the destination point, and the display unit in which the designation input is made by the input unit 104 The search unit 105 can search for a temporary route from the current point of the moving body acquired by the acquisition unit 102 to the destination point via the designated input point on the map information displayed in 101. Then, while executing the route guidance process using the guidance route, the display control unit 108 controls the display unit 101 to display information on the temporary route while the designated input is continued, and when the designated input is released or When the designated input is continued for a predetermined time or more, the display of information on the temporary route can be deleted. Therefore, when the user is guided to the guidance route and wants to check the detour, the detour can be displayed temporarily. Further, both the guidance route and the detour can be displayed. As a result, the user can easily confirm the detour, for example, when the guidance route is congested and wants to confirm the detour. Moreover, since both the guidance route and the detour can be displayed, the guidance route and the temporary route can be compared.

Further, according to the information display device 100 of the present embodiment, the display control unit 108 controls the display unit 101 so that the information related to the temporary route and the information related to the guide route can be compared while the designated input is continued. Can be displayed. Thereby, the user can confirm the original guidance route and the detour without making a mistake.

Further, according to the information display apparatus 100 of the present embodiment, the input unit 104 receives a designation input with the scroll end point by the scroll unit 103 that scrolls the map information displayed on the display unit 101 as the designated input point. be able to. Therefore, for example, when the map information is scrolled so as to display a point desired by the user, the point where the scrolling is completed, that is, the route passing through the point desired by the user can be temporarily displayed. This allows the user to scroll through the map information, for example, to find out the point of interest, for example, the route through the point of interest, the distance traveled through the point of interest, and the prediction of the destination point. You can know more detailed information such as arrival time.

Further, according to the information display device 100 of the present embodiment, when the confirmation unit 106 confirms that the route guidance process is to be performed using the temporary route instead of the guidance route while the temporary route is being displayed. Further, the route guidance process can be executed by changing the guidance route to a temporary route by the route guidance unit 107. Therefore, even when the route guidance process using the guidance route from the current point to the destination point is executed, the route guidance process using the temporary route can be changed. Accordingly, when the user wants to pass the detour while being guided to the guide route, the user can be guided by changing the route to the destination to the detour.

Further, according to the information display device 100 of the present embodiment, the search unit 105 is changed when the position information of the current location of the moving object acquired by the acquisition unit 102 is changed while displaying the temporary route. The temporary route from the current location of the mobile object to the designated input location can be re-searched. Therefore, when the current location of the moving object is changing while displaying the temporary route, the temporary route can be updated according to the change of the current location of the moving object. Thereby, the user can always display a temporary route according to his current location.

Hereinafter, examples of the present invention will be described. In the present embodiment, an example in which the information display device 100 of the present invention is implemented by a navigation device mounted on a moving body such as a vehicle (including a four-wheeled vehicle and a two-wheeled vehicle) will be described.

If the map information is scrolled in step S403 (step S403: Yes), the process waits until the scrolling of the map information is completed (step S404: No loop). If it is determined in step S404 that the scrolling of the map information has been completed (step S404: Yes), the designated input receiving program is executed, and the point mark when it is determined in step S404 that the scrolling of the map information has been completed. The point shown is accepted as the designated input point (step S405).

Then, the temporary route search program is executed to search for a temporary route from the current point of the vehicle received in step S401 to the destination point via the point indicated by the point mark received in step S405 (step S406). ). In step S406, a temporary route may be searched in consideration of traffic regulation and traffic jam information.

Next, the display form setting program is executed to display information on the temporary route in a display form that can be compared with information on the guidance route (step S407). Information on the temporary route is, for example, at least one of the route from the current point of the vehicle to the destination via the designated input point, the travel distance when reaching the destination, and the arrival time to the destination Information.

Next, it is determined whether or not the point mark has been deleted (step S408). If it is not determined that the point mark has been deleted (step S408: No), it is determined whether or not the point mark has been moved (step S409). ). If it is not determined in step S409 that the point mark has been moved (step S409: No), it is determined whether or not the designation input accepted in step S405 has continued for a predetermined time or more (step S410). When it is determined in step S410 that it has not been continued for a predetermined time or longer (step S410: No), a temporary route is used instead of the guide route used in step S402 and used in the continuous route guidance process. It is confirmed whether or not the route guidance process is executed (step S411).

If it is not confirmed that the route guidance process is executed using the temporary route instead of the guidance route in step S411 (step S411: No), the process returns to step S408 and the subsequent processing is repeated. If it is determined in step S408 that the point mark has been deleted (step S408: Yes), or if it is determined in step S409 that the point mark has been moved (step S409: Yes), the process continues in step S410 for a predetermined time or longer. If it is determined (step S410: Yes), the display of information on the temporary route displayed on the display 313 in step S407 is deleted (step S412), the process returns to step S403, and the subsequent processing is repeated.

On the other hand, when it is confirmed in step S411 that the route guidance process is to be executed using a temporary route instead of the guidance route (step S411: Yes), the route guidance program is executed to make the guidance route a temporary route. The route guidance processing is executed after changing (step S413), and the series of processing ends.

In the flowchart of FIG. 4, it is determined in step S404 whether or not the map information has been scrolled, and in step S405, the point indicated by the point mark that is the center of scrolling is accepted as the designated input point. This is not a limitation. The designated input point may not be the center point of scrolling as long as it is a point designated by the user. Specifically, for example, a point double-clicked by the user or a point specified for a predetermined time or more may be accepted as the designated input point.

In the flowchart of FIG. 4, after displaying the information about the temporary route in a display form that can be compared with the information about the guidance route in step S407, the display of the information about the temporary route is deleted in step S412 or guided in step S413. Until the route is changed to the temporary route and the route guidance process is executed, the location information of the current location of the moving body is always acquired, and the temporary route is updated according to the change of the location information of the current location of the moving body. May be.

In the flowchart of FIG. 4, if it is determined in step S409: No that the point mark has not been moved, the process proceeds to step S410 to determine whether or not a predetermined time has elapsed. It is not a thing. Specifically, for example, when it is determined in step S409: No that the point mark has not been moved, step S410 is omitted, and the process proceeds to step S411, where the route guidance process is performed using a temporary route instead of the guidance route. It may be determined whether or not to execute.

(Example of temporary route display)
Next, an example of a temporary route display will be described with reference to FIG. FIG. 5 is an explanatory diagram illustrating an example of displaying a temporary route. As shown in FIG. 5, on the map information displayed on the display 313, the current position 501 of the vehicle, the guide route 502 to the destination point, the center point 503 for scrolling the map information, and the center point 503 for scrolling. A temporary route 504 passing through and information 505 on the guidance route and the temporary route are displayed in an overlapping manner. As described above, in FIG. 5, the route guidance process using the guidance route 502 is continuously executed while the temporary route 504 is displayed.

Further, the information 505 regarding the guide route and the temporary route includes, for example, the travel distance from the current point 501 of the vehicle to the destination point (not shown) on the guidance route 502 and the expected arrival time at the destination point. The travel distance and the estimated arrival time may include, for example, a difference between the guide route 502 and the temporary route 504. Further, the information 505 regarding the guidance route and the temporary route may include an option for confirming with the user whether or not the route guidance processing is executed using the temporary route 504 instead of the guidance route 502. Good. Specifically, the option for confirming with the user is, for example, a button for receiving an input of an instruction as to whether or not to change the guidance route 502 to the temporary route 504. In FIG. 5, when it is confirmed that the route guidance process is executed using the temporary route 504 instead of the guidance route 502, that is, when an instruction to change the guidance route 502 to the temporary route 504 is received, The route guidance process using the route 502 is terminated, and the route guidance process is executed using the temporary route 504.

As described above, according to the navigation device 300 according to the present embodiment, when the route guidance process is executed using the guidance route to the destination, the destination point is passed through the point designated by the user.
