Abstract

A system and method are disclosed for rendering geographically and/or temporally relevant POI information on a mobile client device. A mobile device client transmits its current location to a server. The server determines and transmits to mobile client device geographically and/or temporally relevant POI information based on the received current location of the mobile client device and its predicted future locations. The mobile client device renders the received POI information when it becomes geographically relevant.

Claims

1. An apparatus for persistently determining predictive search results for display on a moving mobile client, the apparatus comprising:

a communication module for persistently receiving a current location of the moving mobile client;

a location determination module, communicatively coupled to the communication module, for persistently locating the moving mobile client relative to a road network map based on the received current location;

a prediction tree generator, communicatively coupled to the location determination module, for persistently predicting a plurality of routes that can be traversed by the moving mobile client on the road network map, the plurality of predicted routes re-predicted responsive to a change in the current location of the moving mobile client; and

a point of interest determination module, communicatively coupled to the prediction tree generator, for persistently determining a plurality of points of interest on the plurality of predicted routes based on a search criteria associated with the moving mobile client.

2. The apparatus of claim 1, wherein:

the communication module further receives one of a speed of the moving mobile client and a heading of the moving mobile client; and

the prediction tree generator uses one of the speed and the heading to predict the plurality of routes.

3. The apparatus of claim 1, further comprising:

a search space generator for generating a search space based on the plurality of predicted routes wherein the point of interest determination module searches the plurality of predicted routes within the search space to determine the plurality of points of interest.

4. The apparatus of claim 3, wherein the search space comprises circles around major intersections within the plurality of predicted routes.

5. The apparatus of claim 1, wherein the communication module transmits to the moving mobile client an initial thin layer and a later thick layer of information about the determined plurality of points of interest, the thin layer comprising a name and a location information about the determined plurality of points of interest, the thick layer comprising user generated POI information about the determined plurality of points of interest.

6. An apparatus for displaying directions to currently relevant points of interest on a moving mobile client, the apparatus comprising:

a communication module for persistently transmitting to a server a current location of the mobile client, and for persistently receiving a plurality of points of interest from the server wherein the plurality of points of interest are based on a search criteria associated with the moving mobile client and the plurality of points of interest are located on a plurality of potential routes predicted to be traversed by the mobile client;

a storage module for storing the received plurality of points of interest; and

a current points of interest determination module, communicatively coupled to the storage module, for persistently determining a current point of interest from the stored plurality of points of interest.

7. The apparatus of claim 6, wherein the current points of interest determination module persistently determines the current point of interest based on a changed current location of the mobile client.

8. The apparatus of claim 6, wherein the communication module receives from the server an initial thin layer and a later thick layer of information about the plurality of points of interest, the thin layer comprising a name and a location information about the plurality of points of interest, the thick layer comprising user generated POI information about the plurality of points of interest.

9. The apparatus of claim 6, wherein the communication module further transmits to the server one from a speed of the mobile client and a heading of the mobile client, and the one of the speed and the heading is used by the server to determine the plurality of points of interest.

10. The apparatus of claim 6, further comprising:

a user interface module for communicating to a user directions for the determined current point of interest.

11. A method for displaying directions to currently relevant points of interest on a moving mobile client, the method comprising:

persistently receiving a current location of the moving mobile client;

persistently locating the moving mobile client on a road network map based on the received current location;

persistently predicting, based on the persistently received current location, a plurality of routes that can be traversed by the moving mobile client on the road network map wherein the plurality of predicted routes change with a change in the current location of the moving mobile client;

persistently determining a plurality of points of interest on the plurality of predicted routes.

12. The method of claim 11, further comprising:

receiving one from a speed of the moving mobile client and a heading of the moving mobile client; and

wherein the plurality of routes are predicted based on the received one of the speed and the heading.

13. The method of claim 11, further comprising:

generating a search space based on the plurality of predicted routes wherein the plurality of determined points of interest are located within the search space and on the predicted plurality of routes.

14. The method of claim 13, wherein the search space comprises circles around the major intersections within the plurality of predicted routes.

15. The method of claim 11, further comprising:

transmitting to the moving mobile client an initial thin layer and a later thick layer of information about the determined plurality of points of interest, the thin layer comprising a name and a location information about the determined plurality of points of interest, the thick layer comprising user generated POI information about the determined plurality of points of interest.

16. A method for displaying directions to currently relevant points of interest on a moving mobile client, the method comprising:

persistently transmitting to a server a current location of the moving mobile client;

persistently receiving a plurality of points of interest from the server wherein the plurality of points of interest are based on a search criteria associated with the moving mobile client and the plurality of points of interest are located on a plurality of potential routes predicted to be traversed by the mobile client;

storing the received plurality of points of interest; and

persistently determining a current point of interest from the stored plurality of points of interest.

17. The method of claim 16, wherein the persistently determined current point of interest is based on a changed current location of the mobile client.

18. The method of claim 16, further comprising:

receiving from the server an initial thin layer and a later thick layer of information about the plurality of points of interest, the thin layer comprising a name and a location information about the plurality of points of interest, the thick layer comprising user generated POI information about the plurality of points of interest.

19. The method of claim 16, further comprising:

transmitting to the server one from a speed of the mobile client and a heading of the mobile client, wherein the one of the speed and the heading is used by the server to determine the plurality of points of interest.

20. The method of claim 16, further comprising:

communicating to a user directions for the determined current point of interest.
