Abstract

A system enabling a user to initiate a requested action via a printed substrate. The system comprises: a printed substrate comprising user information and a position-coding pattern; an optically imaging pen comprising a nib, an image sensor and a processor; and a computer system for identifying and initiating the requested action. The processor is configured for decoding the imaged position-coding pattern, determining a first position using the decoded position-coding pattern, and determining a second position using the first position. The second position is different than the first position, and is used by the computer system to identify the requested action.

Claims

1. A system enabling a user to initiate a requested action via a printed substrate, the system comprising:

a printed substrate comprising user information and a position-coding pattern, said position-coding pattern identifying a plurality of locations on the substrate;

an optically imaging pen comprising;

a nib for interacting with the substrate;

an image sensor for imaging at least part of the position-coding pattern; and

a processor configured for;

decoding the imaged position-coding pattern;

determining a first position using the decoded position-coding pattern; and

determining a second position using the first position, wherein said

second position is different than said first position; and

a computer system configured for receiving the second position, identifying the requested action based on the second position, and initiating the requested action.

2. The system of claim 1, wherein said second position corresponds to a nib position.

3. The system of claim 2, wherein said nib position is determined using a multiple degree-of-freedom perspective transform, a known spatial relationship between the nib and the image sensor and the first position.

4. The system of claim 2, wherein said perspective transform is determined from a perspective distortion of the imaged position-coding pattern.

5. The system of claim 2, wherein said position-coding pattern identifies a page identity associated with the printed substrate.

6. The system of claim 5, wherein the computer system receives the page identity together with the second position.

7. The system of claim 6, wherein the computer system is configured to retrieve a page description corresponding to the page identity.

8. The system of claim 7, wherein the page description describes a zone of at least one interactive element on the printed substrate.

9. The system of claim 8, wherein the interactive element is selected from the group consisting of:

a hyperlink, a button and a field.

10. The system of claim 8, wherein the field is adapted for receiving handwritten input.

11. The system of claim 8, wherein the computer system is configured to identify the action by comparing the second position with the zone of at least one interactive element.

12. The system of claim 1, wherein said pen stores a unique pen identity.

13. The system of claim 1, wherein said nib is coupled to a force sensor.

14. The system of claim 1, wherein said nib is retractable.

15. An optically imaging pen enabling a user to initiate an action via a printed substrate, the printed substrate comprising user information and a position-coding pattern identifying a plurality of locations on the substrate, said pen comprising:

a nib for interacting with the substrate;

an image sensor for imaging at least part of the position-coding pattern;

a processor configured for;

decoding the imaged position-coding pattern;

determining a first position using the decoded position-coding pattern; and

determining a second position using the first position, wherein said second position is different than said first position; and

means for sending the second position to a computer system so to enable the action to be identified and initiated using the second position.
