Abstract

A position related information presentation method, and corresponding system and recording medium storing a corresponding program are provided. The method includes a number of steps. With respect to a display of area information related to a position indicated by data of a three-dimensional map superimposed on the data of the three-dimensional map, information is detected on superimposing of one object on another in a predetermined angle range centered on the moving direction from the current position. Related area information is searched for from the area information using information on superimposing of one object on another. The area information is searched for based on input/output keywords. A path is searched for from the current position to the position specified by the searched area information, wherein a guide to the position specified by the area information is displayed based on this search result.

Claims

1. A position related information presentation system, comprising:

field of view determining means for detecting, with respect to a display of area information related to a position indicated by data of a three-dimensional map superimposed on the data of said three-dimensional map, information on superimposing of one object on another in a predetermined angle range centered on the moving direction from the current position;

position information filtering means for searching for said related area information from said area information using information on superimposing of one object on another;

keyword searching means for searching for said area information based on input/output keywords; and

path searching means for searching for a path up to the position specified by said area information searched from the current position by said keyword searching means.

2. The position related information presentation system according to claim 1, wherein said path searching means researches for said path every time whenever said current position is changed.

3. A position related information presentation method, comprising the steps of:

detecting, with respect to a display of area information related to a position indicated by data of a three-dimensional map superimposed on the data of said three-dimensional map, information on superimposing of one object on another in a predetermined angle range centered on the moving direction from the current position;

searching for said related area information from said area information using information on superimposing of one object on another;

searching for said area information based on input/output keywords; and

searching for a path from the current position to the position specified by said searched area information, wherein a guide to the position specified by said area information is displayed based on this search result.

4. The position related information presentation method according to claim 3, wherein said path is searched every time whenever said current position is changed.

5. A computer readable medium for storing a position related information presentation control program, when executed by a computer, for presenting position related information through the steps of:

detecting, with respect to a display of area information related to a position indicated by data of a three-dimensional map superimposed on the data of said three-dimensional map, information on superimposing of one object on another in a predetermined angle range centered on the moving direction from the current position;

searching for said related area information from said area information using said information on superimposing of one object on another;

searching for said area information based on input/output keywords; and

searching for a path up to the position specified by said area information searched from the current position.

6. A portable terminal apparatus of a position related information presentation system, comprising:

superimposed displaying means for displaying area information related to a position expressed with data of a three-dimensional map superimposed on the data of said three-dimensional map;

field of view determining means for detecting information on superimposing of one object on another in a predetermined angle range centered on the moving direction from the current position with respect to the display of said superimposed displaying means;

position information filtering means for searching for said related area information from said area information related to a new display position detected in response to a display change instruction using said information on superimposing of one object on another;

keyword searching means for searching for said area information based on input/output keywords; and

path searching means for searching for a path up to the position specified by said area information searched from the current position by said keyword searching means, wherein a guide to the position specified with said area information is displayed based on the search result by said path searching means.

7. A position related information presentation method including a portable terminal apparatus, comprising the steps of:

displaying area information related to a position expressed with data of a three-dimensional map superimposed on the data of said three-dimensional map;

detecting information on superimposing of one object on another in a predetermined angle range centered in the moving direction from the current position with respect to the display;

searching for said related area information from said area information using said information on superimposing of one object on another;

searching for said area information based on input/output keywords; and

searching for a path from the current position to the position specified by said searched area information, wherein a guide to a position specified by said area information is displayed based on this search result.

8. A computer readable medium for storing a position related information presentation control program, when executed by a portable computer, for presenting position related information through the steps of:

displaying area information related to a position expressed with data of a three-dimensional map superimposed on the data of said three-dimensional map;

detecting information on superimposing of one object on another in a predetermined angle range centered on the moving direction from the current position with respect to the display;

searching for said related area information from said area information using said information on superimposing of one object on another;

searching for said area information based on input/output keywords;

searching for the path from the current position to the position specified by said searched area information; and

displaying a guide to the position specified by said area information based on this search result.
