Abstract

Methods and devices for storing, retrieving and using information are described. A pattern of markings on a surface is decoded to recover information encoded by the pattern. A software application associated with the information is identified. The information can then be used with the software application.

Claims

1. A method of retrieving and using recorded information, said method comprising:

decoding a first pattern of markings on a surface to recover information encoded by said first pattern;

identifying a software application associated with said information; and

using said information with said software application.

2. The method of claim 1 further comprising combining said information with other information stored in memory for said software application to increase content usable with said software application.

3. The method of claim 1 further comprising accessing other information indexed by said information encoded by said first pattern, wherein said other information is used with said software application.

4. The method of claim 3 wherein said other information comprises phonemes used for phonetics-to-speech synthesis.

5. The method of claim 3 wherein said other information comprises a database used for identifying an item of content located on said surface in proximity to said first pattern of markings.

6. The method of claim 1 wherein said software application is for audibly rendering information encoded in said first pattern of markings.

7. The method of claim 1 wherein said surface further comprises a visual cue associated with scanning said first pattern of markings.

8. The method of claim 1 further comprising audibly rendering a message in response to reading information encoded in a second pattern of markings on said surface, said message comprising directions for scanning said first pattern of markings.

9. A method of retrieving and using recorded information, said method comprising:

decoding a first pattern of markings on a surface to recover first information encoded by said first pattern; and

combining said first information encoded on said surface with second information resident in memory to produce a software application.

10. The method of claim 9 wherein said first information comprises information identifying said software application.

11. The method of claim 9 wherein said second information describes a template for said software application, wherein said combining comprises populating said template with said first information to parameterize said software application.

12. The method of claim 9 wherein said first information comprises a reference to third information usable with said software application.

13. The method of claim 12 wherein said third information comprises phonemes used for phonetics-to-speech synthesis.

14. The method of claim 9 wherein said first pattern is demarcated to indicate a beginning and an ending of said first information.

15. The method of claim 9 wherein said surface further comprises a visual cue indicating a direction for scanning said first pattern of markings.

16. The method of claim 9 further comprising audibly rendering a message in response to reading information encoded in a second pattern of markings on said surface, said message comprising directions for scanning said first pattern of markings.

17. A device comprising:

a light-sensitive sensor for receiving light reflected from a surface;

a processor coupled to said sensor; and

a memory coupled to said processor, said memory unit containing instructions that when executed implement a method for retrieving and using recorded information, said method comprising;

sensing a first pattern of markings on said surface;

decoding said first pattern of markings to recover information encoded by said first pattern;

associating said information with a first software application; and

executing said first software application using said information.

18. The device of claim 17 further comprising a speaker for audibly rendering a message encoded by said first pattern of markings.

19. The device of claim 17 wherein said method further comprises combining said information with other information stored in said memory for said first software application to increase content associated with said first software application.

20. The device of claim 17 wherein said executing further comprises populating a template with said information to parameterize a second software application.

21. The device of claim 17 wherein said method further comprises accessing other information indexed by said information encoded by said first pattern, wherein said other information is used with said first software application.

22. The device of claim 21 wherein said other information comprises phonemes used for phonetics-to-speech synthesis.

23. The device of claim 21 wherein said other information comprises a database used for identifying an item of content located on said surface in proximity to said first pattern of markings.

24. The device of claim 17 wherein said information encoded in said first pattern comprises a beginning tag to indicate a beginning of said information and an ending tag to indicate an ending of said information.

25. The device of claim 17 wherein said surface further comprises a visual cue indicating a direction said sensor is to be moved across said first pattern.

26. The device of claim 17 further comprising a speaker for audibly rendering a message in response to said sensor sensing a second pattern of markings on said surface, said message comprising directions for reading said first pattern of markings.

27. A pen-shaped device comprising:

an optical sensor for detecting images on a surface;

a processor coupled to said optical sensor; and

a memory coupled to said processor, said memory unit containing instructions that when executed implement a method for retrieving and using recorded information from said surface, said method comprising;

using said optical sensor to sense encoded data representing said recorded information from said surface;

decoding said encoded data to recover said recorded information wherein said recorded information identifies a software application resident in said memory; and

supplying a portion of said recorded information to said software application.

28. A device as described in claim 27 wherein said method further comprises executing said software application using said portion of said recorded information.

29. A device as described in claim 27 wherein said surface comprises printed images thereon and wherein said portion of said recorded information causes said software application to execute in a manner related to said images.

30. A device as described in claim 27 wherein said surface comprises printed images thereon and wherein said portion of said recorded information comprises data related to said images.

31. A device as described in claim 27 wherein said recorded information further comprises program code executable by said processor.

32. A device as described in claim 27 wherein said recorded information further comprises parameterization data for altering execution of said software application.

33. A device as described in claim 27 wherein said memory comprises a plurality of software applications.

34. A device as described in claim 27 wherein said memory comprises a database of information and wherein said surface comprises a standardized template printed thereon and wherein said portion of said recorded information provides an association between elements of said template and elements of said database.

35. A device as described in claim 27 wherein said memory comprises a database of information and wherein said encoded data comprises an index that points to an item in said database.
