DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a map display device using a computer, and more particularly to managing a history of past events (for example, editing, referencing, searching, etc.) on a map and utilizing the history for subsequent work. Related to technology.

[0002]

2. Description of the Related Art There is known a map display device which displays a map on a screen and allows various events such as location search and route search on the map.

[0003]

In the course of working on this map, a request may be made to go back to the location where the event was previously performed, to perform another event or to confirm the result of the previous event. Often there. In such a case, in the conventional map display device, the user must remember the previous event location, search for the location by scrolling the map on the screen, or the like. This search for a location by scrolling is extremely difficult and time-consuming, especially when it is desired to go to a previous location far from the current location while displaying a detailed map. For example, when displaying a detailed city map of Kasumigaseki, Chiyoda-ku, Tokyo, and wanting to go to a detailed city map of Kokura-Kita-ku, Kitakyushu-shi, Fukuoka Prefecture, if you scroll with that detailed map, You can say that you get lost in the middle of a scroll. To avoid getting lost, it is necessary to temporarily increase the scale of the map, display a wide area map, and scroll on the wide area map. However, since the exact location of the previous event location cannot be seen on the wide area map, it is necessary to return to a detailed map again in the final stage and search for a destination point, which is troublesome.

Accordingly, it is an object of the present invention to provide a map display device which can easily jump to a location of an event which has been performed on a map in the past.

Another object of the present invention is to enable a user to easily jump to a location where an event has previously occurred on a file to be edited, even in an application other than a map, for example, for editing a document, an image, or multimedia. It is in.

[0006]

According to a first aspect of the present invention, there is provided a map display device, wherein when a predetermined event occurs with respect to any place element on a map, the name of the place element relating to the event is generated. And an event history storage unit for storing coordinates, a history menu display unit for displaying a history menu showing a list of stored names, a name designation unit for designating a name from the history menu, From the coordinates, get the coordinates corresponding to the specified name,
A map display unit that displays a map of a region including the location of the acquired coordinates.

[0007] According to this map display device, a predetermined event (for example, pasting of a figure) is performed for a certain location element on the map (for example, various things such as a point, facility, area, route, and place name can be considered). , Searching for a location element, editing the map itself, etc.), the name and coordinates of that location element (typically latitude and longitude,
Any coordinate value may be used as long as the location on the map can be specified), and a list of names stored so far is displayed as a history menu. When the user selects an arbitrary name from the history menu, the display map automatically jumps to a location of coordinates corresponding to the name. Accordingly, the map display can be instantaneously moved to the place where the action was performed before.

[0008] An editing device according to a second aspect of the present invention comprises:
When a predetermined event occurs with respect to any of the elements included in the file to be edited, an event history storage for storing the name of the event or the element and element specifying information for specifying the element in the file to be edited Section, a history menu display section for displaying a history menu showing a list of saved names, a name designation section for designating a name from the history menu, and designation from among the saved element identification information. A display unit for acquiring element identification information corresponding to the acquired name and displaying an element specified by the acquired element identification information in the file to be edited.

According to this editing apparatus, a predetermined event (for example, various things such as a character, a character string, an image area, a ruled line, a figure, and a symbol) can be considered for any element in the file to be edited. For example, various things such as character input, ruled line entry, character modification, graphic drawing, image manipulation, area selection, copy, paste, etc. can be considered), the event or element name and the file A set with element identification information for identifying the element is stored,
A list of names saved so far is displayed as a history menu. When the user selects an arbitrary name from the history menu, the element in the file specified by the element embankment information corresponding to the name is displayed. Therefore, it is possible to instantly find the element that has performed the action before.

The HTML file downloaded from the map application server 29 includes user graphic information in the same format as that edited by the graphic editing unit 5, and the downloaded user graphic information is also stored in a disk or the like. Storage is saved.

The information of the user graphic stored in the storage as described above is read when the map engine 3 displays the map, and is stored in a location on the map corresponding to the latitude and longitude described in each user graphic information. , And are superimposed on the map image.

The search unit 13 holds, as search keys, names of various place elements (for example, address names, postal codes, telephone numbers, facility names, and user graphic names) existing within the entire map range covered by the map database 19. The search key list is displayed on the display 31 as a search menu. Then, when the user specifies an arbitrary search from the search menu, the search unit 13 searches for the latitude and longitude of the place corresponding to the search key, and passes it to the map engine 3.
The map engine 3 moves the map displayed on the display 31 so that the passed latitude and longitude become the center of the map.

Each time the graphic editing unit 5, the download unit 7, the route search unit 9, and the GPS unit 11 store the user graphic information in the storage, the name and the latitude and longitude of the stored user graphic are recorded in the history. Notify the stacker 15. Further, each time a search is performed, the search unit 13 described above stores the search key (that is, address name, postal code, telephone number, facility name, user graphic, or the like) used in the search and the searched latitude / longitude as a history stacker. 15 is notified. The history stacker 15 uses the set of the notified user graphic name or search key (both are hereinafter collectively referred to as "place element names") and the latitude and longitude as individual records as a history file 21 on the storage. To be stored.

The history display unit 17 reads the history file 21 and registers the location element names in the history file 21 in the history menu 23 in the form of a list.
The history menu 23 is displayed on the display. When the user selects an arbitrary place element name from the displayed history menu 23, the history display unit 17 obtains the latitude and longitude of the selected place element name from the history file 21 and sends it to the map engine 3. hand over. The map engine 3 moves the map displayed on the display 31 so that the passed latitude and longitude become the center of the map.

With the above function, when an event such as a user figure is drawn or a search is made at a certain place on the map, the place element name of the place where the event occurred is automatically registered in the history menu 23. And
By simply selecting an arbitrary place element name from the history menu 23, the display map can be jumped to an arbitrary event occurrence place. Hereinafter, a specific description will be given.

FIG. 2 shows an example of a graphic user interface (GUI) displayed on the display 31 by the map application 1.

This GUI has a map window 41 for displaying a map on a wide screen area, a guide window 43 for displaying a map on a small screen area, and a search window 44 for displaying a search menu 45. Map window 41
