Abstract

An information providing system includes a terminal and a server. The information providing system includes: an information database configured to record registration data in relation to position data; a position data acquiring section configured to acquire a position data of the terminal; a state acquiring section configured to acquire a state data indicative of a state of the terminal; and a region determining section configured to determine a specified retrieval region of the registration data based on the state data. An information extracting section is configured to extract the registration data in the specified retrieval region from the information database as browser data, and a display section is configured to display the browser data.

Claims

1. An information providing system comprising a terminal and a server,

wherein said terminal comprises:

a position data acquiring section configured to acquire a position data of said terminal; and

a display section configured to display browser data, and

wherein said server comprises;

an information database configured to record registration data in relation to said position data;

a state data acquiring section configured to acquire state data indicating a state on a movement of said terminal;

a region determining section configured to determine a specified retrieval region which is changed in response to said state data;

an information extracting section configured to extract as said browser data from said information database, said registration data in which said position data corresponding to said registration data are included in said specified retrieval region.

2. The information providing system according to claim 1, wherein said state data includes a terminal movement speed and a terminal movement direction, and

wherein said region determining section extends said specified retrieval region in the terminal movement direction in response to said movement speed.

3. The information providing system according to claim 2, further comprising:

an orientation data acquiring section configured to measure an orientation of said terminal,

wherein said state data further comprises said terminal orientation, and

wherein said region determining section performs a correction of a data indicating what degree said specified retrieval region should be extended to into said terminal direction when said terminal movement direction and said terminal orientation do not coincide.

4. The information providing system according to claim 1, wherein said specified retrieval region is a region of an ellipsoidal shape with a longer axis in said terminal movement direction, and

wherein said region determining section determines said specified retrieval region, to extend an ellipsoidal region in direction of the longer axis based on said terminal movement speed.

5. The information providing system according to claim 4, wherein said region determining section performs a correction of said specified retrieval region to extend a short axis of said ellipsoidal region into a direction said terminal orientation, when said terminal movement direction and said terminal orientation do not coincide.

6. The information providing system according to claim 1, wherein said specified retrieval region is a region of a fan shape which has an angle with a central line in said terminal movement direction, and

wherein said region determining section performs a correction of said fan shape region to extend a radius of said fan shape in response to increase of said movement speed.

7. The information providing system according to claim 6, said region determining section performs a correction of said specified retrieval region such that said angle of said fan shape is widened into said terminal movement direction, when said terminal movement direction and said terminal orientation do not coincide.

8. The information providing system according to claim 1, wherein said position data acquiring section acquires said position data periodically, and

wherein said state acquiring section calculates said movement speed and said terminal movement direction based on said position data acquired by said position data acquiring section.

9. The information providing system according to claim 1, further comprising:

a region table in which the retrieval region is stored in relation to said state data,

wherein said region determining section extracts said retrieval region based on said state data calculated by said state acquiring section as said specified retrieval region.

10. The information providing system according to claim 1, wherein said region determining section calculates said specified retrieval region by using a preset equation based on said state data.

11. The information providing system according to claim 3, further comprising:

an addition parameter table in which a parameter is stored,

wherein said region determining section perform a correction to extend said specified retrieval region by using said parameter, when said terminal movement direction and said terminal orientation do not coincide.

12. An information providing method in an information providing system comprising a terminal and a server, said information providing method comprising;

storing registration data in relation to a position data;

acquiring said position data of said terminal;

acquiring a state data indicative of a state on a movement of said terminal;

determining a specified retrieval region which is changed in response to said state data;

extracting as browser data from said information database, said registration data in which said position data corresponding to said registration data are included in said specified retrieval region; and

displaying said browser data.

13. The information providing method according to claim 12, wherein said state data includes a terminal movement speed and a terminal movement direction,

wherein said determining comprises:

determining said specified retrieval region to extend said specified retrieval region in said terminal movement direction based on said state data.

14. The information providing method according to claim 13, further comprising:

measuring an orientation of said terminal,

wherein said state data further comprises said terminal direction,

wherein said determining performs a correction of said specified retrieval region based on said state data, to extend said specified retrieval region into a direction of said terminal orientation, when said terminal movement direction and said terminal orientation do not coincide.

15. The information providing method according to claim 12, wherein said specified retrieval region is a region of an ellipsoidal shape with a longer axis in said terminal movement direction, and

wherein said determining comprises:

determining said specified retrieval region, to extend an ellipsoidal region in direction of the longer axis based on said terminal movement speed.

16. The information providing method according to claim 15, wherein said determining comprises:

performing a correction of said specified retrieval region to extend a short axis of said ellipsoidal region into a direction of the movement orientation, when said terminal movement direction and said terminal orientation do not coincide.

17. The information providing method according to claim 16, wherein said specified retrieval region is a region of a fan shape which has an angle with a central line in said terminal movement direction, and

wherein said determining comprises:

performing a correction of said fan shape region to extend a radius of said fan shape in response to increase of said movement speed.

18. The information providing method according to claim 17, wherein said determining comprises:

performing a correction of said specified retrieval region such that said angle of said fan shape is widened into said terminal movement direction, when said terminal movement direction and said terminal orientation do not coincide.

19. The information providing method according to claim 12, wherein said position data acquiring section acquires said position data periodically, and

wherein said state acquiring section calculates said movement speed and said terminal movement direction based on said position data acquired by said position data acquiring section.
