Abstract

A system that the tracks a likely object within the user'"'"'s field of view. This is done by taking a picture of the field of view, and processing that picture to determine likely objects within the picture being viewed. Those likely objects are than correlated against a database, and information about the objects are returned. The information can be either raw information that is sent over an information link, or an address to local information. The information sent back can indicate, for example, more information about a painting being viewed, or more information about a theme park attraction.

Claims

1. A computer system comprising:

an image acquiring device which obtains information indicative of an image of a scene, and wherein said image includes an artifact within the scene; and

a processor, which processes said information to determine likely artifact information within said scene, and provides artifact-sensitive information indicative of said artifact within said scene.

2. A system as in claim 1, wherein said image acquiring device includes a camera.

3. A system as in claim 1, further comprising a handheld computer, associated with said image acquiring device.

4. A system as in claim 3, wherein said processor is also associated with said handheld computer.

5. A system as in claim 3, further comprising a network element, associated with said handheld computer, and operating to send said information over a network to a remote location.

6. A system as in claim 5, wherein said network element comprises a wireless network element.

7. A system as in claim 1, wherein said artifact information includes an item of art.

8. A system as in claim 1, wherein said artifact information includes area information within a constrained area.

9. A system as in claim 1, wherein said artifact sensitive information comprises an address of locally stored information.

10. A system as in claim 5, wherein said network element connects to a remote processor, and wherein said artifact sensitive information comprises information from a remote source which describes said artifact.

11. A system as in claim 3, further comprising a position detecting part, which detects a position of said handheld computer, and wherein said processor is also responsive to said position.

12. A system as in claim 11, wherein said position detecting part is a global positioning satellite (GPS) part.

13. A system as in claim 3, wherein said processor also processes said information to determine a likely position of said handheld computer.

14. A system as in claim 1, wherein said processor determines features of interest within said scene.

15. A system, comprising:

a handheld computer including a processor, an image acquiring device which obtains an image of a scene being viewed, and a network part, said handheld computer coupling information indicative of said image to said network part, and receiving information indicative of specific parts within said image from said network part.

16. A system as in claim 15, further comprising a network processor, which processes said image to determine specific artifacts therein based on features of interest, and returns information which is specific to said specific artifacts.

17. A system as in claim 15, wherein said network part includes a wireless network part.

18. A system as in claim 15, wherein said processor operates to determine candidate features within said image.

19. A system as in claim 18, wherein said candidate features include one of edges, frames, or specified lighting effects.

20. A system as in claim 15, wherein said image acquiring device includes a camera.

21. A system as in claim 15, further comprising a location determining device which provides information indicative of location of said network part.

22. A system as in claim 17, wherein said network part is one of bluetooth, or 802.11 wireless network protocol.

23. A system as in claim 15, wherein said handheld computer is a personal digital assistant (PDA).

24. A system as in claim 15, wherein said handheld computer is a cellular telephone.

25. A method, comprising:

obtaining an image of an area around a user;

processing said image to determine salient features within said image of a specified type, which relate to a specified object within the image;

determining a most likely object within the image to represent an object of interest; and

returning information about said most likely object to the user.

26. A method as in claim 25, wherein said returning comprises returning an address of additional information about said most likely object.

27. A method as in claim 25, wherein said returning comprises returning actual information about said likely object.

28. A method as in claim 25, further comprising displaying said information about said most likely object.

29. A method as in claim 25, wherein said obtaining comprises obtaining an image using a handheld computer.

30. A method, comprising:

forming a database including a plurality of images of objects;

associating information with each of said plurality of objects;

automatically determining, using an image acquiring element, one of said objects in said database being viewed by said user; and

determining information associated with said objects in said database.

31. A method as in claim 30, wherein said forming comprises obtaining multiple images for at least a plurality of the objects, and said multiple images representing the objects as seen in different conditions.

32. A method as in claim 31, wherein said different conditions comprise different lighting.

33. A method as in claim 31, wherein said different conditions comprise different angles.

34. A method as in claim 31, further comprising obtaining an image in a handheld computer, and using said image to access said database.

35. A method as in claim 34, wherein said using comprises extracting parts of the image which are likely to be relevant, and accessing said image database with said parts.

36. A method as in claim 34, further comprising determining a location of said handheld computer.

37. A method as in claim 36, wherein said determining comprises automatically determining said location using a global positioning satellite system.

38. A method as in claim 36, wherein said determining comprises a determining said location using said image.

39. An article comprising:

a machine-readable medium which stores machine-executable instructions, the instructions causing a machine to;

acquire an electronic representation of an image indicative of the scene with an artifact within the scene; and

process the electronic representation to provide information indicative of the artifact.

40. An article as in claim 39, wherein said process comprises determining likely candidate features within the electronic representation, and using said features to access a database of known artifacts.

41. An article as in claim 40, further comprising accessing said database to determine said information indicative of the identified artifact.
