Abstract

The present invention is directed to a map application system that employs an automatic stroll method of strolling through a virtual space into the route and distribution information change according to the interests of a user and the time of day (ie. daytime vs. nighttime, etc.). In the present invention, an article contributed to a contribution server from a contribution terminal is stored temporarily in a contribution DB. Each article is converted to information related to a spatial position by a spatial information structure process and is stored in a spatial information DB. The contribution server returns an article with the relation to the position of the neighborhood according to the input of a region name on a stroll terminal. The stroll terminal starts a stroll on the basis of a region name inputted as an initial value, and automatically sets a route on the basis of the interest information of a user. Information about the route is provided from contribution server and is appropriately displayed.

means for calculating, for at least one route between the present position and said destination, nodes dividing said route, selecting distribution information corresponding to the position neighborhood at said node on the basis of interest information of a user including a degree of interest for a plurality of kinds of distribution information, and displaying on said display device said selected distribution information serially with said nodes along the route in order.

7. A map application system according to claim 6, further comprising:

means for storing the position information corresponding to said displayed distribution information into said storage device when said distribution information is displayed on said display device;

means for decreasing a value of weighting of said distribution information already displayed when weighting said distribution information; and

means for decreasing a value of weighting of said route that has already been passed by referring to position information stored in said storage device.

8. A map display control method, using a processing unit with a display device and a storage device, for strolling along a virtual space composed of information of things that exist on a screen of said display device, the method comprising the steps of:

(a) registering user interest information including degree of interest for a plurality of kinds of distribution information into said storage device;

(b) inputting a present position;

(c) receiving contents of distribution information associated with a spatial position, and doing weighting for distribution information of a neighborhood of said inputted present position on the basis of a distance from the present position and interest information of a user;

(d) calculating a destination included in said-.distribution information on the basis of said weighting;

(e) calculating, for at least one route between the present position and said destination, nodes suitably dividing said route;

(f) selecting distribution information corresponding to a neighborhood at said calculated node on the basis of interest information of a user including a degree of interest for a plurality of kinds of distribution information;

(g) displaying on said display device said selected distribution information serially with said nodes along the route in order; and

(h) updating information of said present position after having displayed all of said distribution information, and repeating said steps (a) to (g).

9. A map display control method according to claim 8, wherein said step (g) further comprises the substeps of:

(g1) displaying on said display device a map including a present position;

(g2) displaying on said display device object indicating said present position;

(g3) displaying said distribution information of said present position adjacent to said map according to the user'"'"'s interests;

(g4) scrolling smoothly said map so that said present position moves toward a destination direction; and

(g5) repeating said steps (g3) and (g4).

10. A map display control method according to claim 8, wherein said step (g) further comprises the substeps of:

(g6) changing a reduced scale of said map and displaying a wide area map in case a quantity of distribution information included in the neighborhood of the present position is smaller than a predetermined first value;

(g7) changing a reduced scale of said map and displaying an expansion map in case in case a quantity of distribution information included in the neighborhood of the present position is larger than a predetermined second value; and

(g8) changing a neighborhood distance calculation method adjusting to said map reduced scale changed in said step (g6) or (g7).
