Abstract

An interface is provided to a mobile navigation system in which an optical image of a point-of-interest acquired by cellular telephone devices is an input to the system. Textual and optionally other location information is extracted from the image, and used by the navigation system to identify coordinates and vectors relating to the point-of-interest. The results are stored and may be subsequently recalled to provide mapping and routing information to the cellular telephone device, whose position relative to the point-of-interest may have changed. Optical images may be uploaded from telephone device to the navigation system automatically or interactively, and can be processed remotely, generally without further user interaction.

Claims

1. A method for navigation, comprising the steps of:

capturing an image using a mobile device;

transferring data relating to said image to a remote facility;

processing said image to identify a location associated with said image; and

communicating information from said remote facility to said mobile device describing navigation to said location.

2. The method according to claim 1, wherein processing said image comprises wirelessly transmitting said image from said mobile device to a remote server.

3. The method according to claim 1, wherein processing said image comprises performing optical character recognition.

4. The method according to claim 3, wherein said step of processing said image is performed in said mobile device.

5. The method according to claim 3, wherein said step of processing said image is performed in a remote server.

6. The method according to claim 1, wherein processing said image comprises referencing an image database.

7. The method according to claim 1, wherein said mobile device is a cellular telephone having a camera incorporated therein.

8. The method according to claim 1, wherein said step of capturing an image comprises the steps of:

acquiring said image with another mobile device; and

transmitting said image from said another mobile device to said mobile device.

9. A computer program product for supporting mobile navigation, including a tangible computer-readable medium in which computer program instructions are stored, which instructions, when read by a computer, cause the computer to command a mobile device having a photographic capability to:

capture an image;

transmit said image to a remote dynamic navigation facility;

instruct said facility to identify a location in said image; and

instruct said facility to transmit to said mobile device information describing navigation to said location.

10. The computer program product according to claim 9, wherein said instructions cause the computer to command said mobile device to instruct said facility to perform optical character recognition on said image and to identify said location using textual data obtained therefrom.

11. The computer program product according to claim 9, wherein said instructions cause the computer to command said mobile device to instruct said facility to process said image by referencing an image database and to identify said location using information obtained from said image database.

12. The computer program product according to claim 9, wherein said mobile device is a cellular telephone having a camera incorporated therein.

13. A mobile information device for supporting mobile navigation, comprising:

a transmitter;

a camera;

a memory having stored therein program instructions; and

a processor operative for executing said instructions, wherein said instructions cause said processor to command said camera to capture an image, said instructions further causing said processor to command said transmitter to transmit said image to a remote dynamic navigation facility, instruct said facility to identify a location in said image, and instruct said facility to transmit to said mobile information device information describing navigation to said location.

14. The mobile information device according to claim 13, wherein said instructions cause said processor to instruct said facility to process said image by performing optical character recognition thereon and to identify said location using textual data obtained therefrom.

15. The mobile information device according to claim 13, wherein said instructions cause said processor to instruct said facility to process said image by referencing an image database and to identify said location using information obtained therefrom.

16. The mobile information device according to claim 13, wherein said mobile information device is a cellular telephone.

17. A method for navigation, comprising the steps of:

capturing an image using a mobile device;

transferring said image to a remote facility;

processing said image to identify textual information associated with said image;

processing said textual information in a navigation system to identify a location associated with said image; and

communicating information from said navigation system to said mobile device describing navigation to said location.

18. The method according to claim 17, wherein processing said image comprises wirelessly transmitting said image from said mobile device to said remote facility.

19. The method according to claim 17, wherein said step of processing said image is performed in said mobile device.

20. The method according to claim 17, wherein said step of processing said image is performed in said remote facility.
