Abstract

Method and system for information association based on an absolute position coding pattern comprising dots or markings which codes coordinates for a position on an imaginary surface. The imaginary surface comprises several regions which are divided in areas, each defined by said coordinates. Handwritten information is digitized by a handheld device which is moved over a surface provided with said pattern and acts like a pen to make notes on the surface. At the same time, the pattern is sensed and coordinates for the pen is calculated regularly. By passing the handheld device over the borderline between areas having different coordinates, a hyperline is generated having a discontinuity. Such a hyperline is easily recognized by the computer system and is used for connecting information at different areas, giving information some properties, like color, or performing an action on the information, such as encryption, or transferring the information to a recipient.

Claims

1. A method for generating an association with regard to information, which is arranged on at least one support provided with an absolute position coding pattern, by means of a handheld device arranged to sense said absolute position coding pattern, comprising:

passing said handheld device over said support for sensing said absolute position coding pattern;

sensing when said handheld device passes over a discontinuity in the absolute position coding pattern; and

interpreting said discontinuity as an association regarding the information present on said supports,

wherein said support comprises a first area in which said absolute position coding pattern codes continuous first coordinates, and that said information is provided on said first area and is connected to said first coordinates, and said support comprises a second area provided with an absolute position coding pattern which codes second coordinates which are discontinuous with said first coordinates;

passing said handheld device in a single movement from one area to the other area, for sensing said discontinuity.

2. The method as claimed in claim 1, in wherein said association involves that a predetermined action is undertaken on said information.

3. The method as claimed in claim 2, wherein said action comprises sending the information as a message, such as an e-mail, SMS or fax, to a recipient.

4. The method as claimed in claim 3, wherein said recipient is defined in the information.

5. The method as claimed in claim 3, wherein said recipient is defined by said association.

6. The method as claimed in claim 5, wherein said recipient is defined by the coordinates in said second area, which are connected to information about the recipient.

7. The method as claimed in claim 2, wherein said action comprises storing said information in a predetermined location in a computer system.

8. The method as claimed in claim 7, wherein said location is a predetermined folder in a personal computer defined by the coordinates of the second area.

9. The method as claimed in claim 2, wherein said action comprises an operation to be performed on said information, such as encryption or character recognition.

10. The method as claimed in claim 1, wherein said association involves a qualification of the information.

11. The method as claimed in claim 10, wherein said qualification is selected from the group comprising:

underline, color, line width, yellow mark, secret, and personal.

12. The method as claimed in claim 11, wherein the information which is qualified is selected by passing said handheld device from said second area, to said first area and encircling said information to be qualified.

13. The method as claimed in claim 11, wherein the information which is qualified is selected by passing said handheld device from said second area, to said first area and encircling said information to be qualified and back to said second area.

14. The method as claimed in claim 2, wherein said first area comprises first information and that said second area comprises second information, and that said association involves that said first and second information are interconnected to a single piece of information.

15. The method as claimed in claim 2, characterized in providing at least a further area comprising coordinates which are discontinuous with said first and second coordinates, and passing said handheld device in a single movement over all areas.

16. The method as claimed in claim 15, wherein said further area comprises a link to personal information, such as a v.card file.

17. A system for generating an association with regard to information, which is arranged on at least one support provided with an absolute position coding pattern, by means of a handheld device arranged to sense said absolute position coding pattern, comprising:

a means for sensing when said handheld device passes over a discontinuity in the absolute position coding pattern; and

interpretation means for interpreting said discontinuity as an association regarding the information present on said support,

wherein said support comprises a first area in which said absolute position coding pattern codes continuous first coordinates, and that said information is provided on said first area and is connected to said first coordinates, and in that said support comprises a second area provided with an absolute position coding pattern which codes second coordinates which are discontinuous with said first coordinates;

which discontinuity is sensed by the handheld device when it passes in a single movement from one area to the other area, for sensing said discontinuity.

18. The system as claimed in claim 17, wherein said association involves that a predetermined action is undertaken on said information.

19. The system as claimed in claim 18, wherein said action comprises sending the information as a message, such as an e-mail, SMS or fax, to a recipient.

20. The system as claimed in claim 19, wherein said recipient is defined in the information.

21. The system as claimed in claim 19, wherein said recipient is defined by said association.

22. The system as claimed in claim 21, wherein said recipient is defined by the coordinates in said second area, which are connected to information about the recipient.

23. The system as claimed in claim 18, wherein said action comprises storing said information in a predetermined location in a computer system.

24. The system as claimed in claim 23, wherein said location is a predetermined folder in a personal computer defined by the coordinates of the second area.

25. The system as claimed in claim 19, wherein said action comprises an operation to be performed on said information, such as encryption or character recognition.

26. The system as claimed in claim 18, wherein said first area comprises first information and that said second area comprises second information, and that said association involves that said first and second information are interconnected to a single piece of information.

27. The system as claimed in claim 18, providing at least a further area comprising coordinates which are discontinuous with said first and second coordinates, and passing said handheld device in a single movement over all areas.

28. The system as claimed in claim 27, wherein said further area comprises a link to personal information, such as a v.card file.

29. The system as claimed in claim 17, wherein said association involves a qualification of the information.

30. The system as claimed in claim 29, wherein said qualification is selected from the group comprising:

underline, color, line width, yellow mark, secret, and personal.

31. The system as claimed in claim 30, wherein the information which is qualified is selected by passing said handheld device from said second area, to said first area and encircling said information to be qualified.

32. The system as claimed in claim 30, wherein the information which is qualified is selected by passing said handheld device from said second area, to said first area and encircling said information to be qualified and back to said second area.
