Abstract

A system for initiating an action in a processing system. The system comprises a printed page having an interactive element enabling user interaction with the page; an optically imaging sensing device for interacting with the interactive element and generating indicating data using sensed coded data; and a processing system configured for: receiving the indicating data, identifying a page description corresponding to the printed page; identifying the interactive element and initiating an action associated with the interactive element. The printed page comprises a plurality of coded data portion, each containing a code pattern encoding a unique location on the page and identifying a page identity.

Claims

1. A system for initiating an action in a processing system, said system comprising:

a printed page comprising an interactive element enabling user interaction with the page, said interactive element being defined by a zone containing graphical information and a plurality of unique coded data portions;

an optically imaging sensing device for interacting with said interactive element and generating indicating data using sensed coded data, said indicating data identifying the identity of the page and a position of the sensing device relative to the page; and

a processing system configured for;

receiving the indicating data;

identifying a page description corresponding to the printed page;

identifying the interactive element using the position of the sensing device and a description of the interactive element contained in the page description; and

initiating an action associated with said interactive element,

wherein each coded data portion contains a code pattern encoding a unique location on the page and identifying a page identity.

2. The system of claim 1, further comprising a printer for printing the page on demand.

3. The system of claim 2, wherein said printer is connected to a computer system configured for generating the printed page.

4. The system of claim 3, wherein said computer system is configured for:

(i) determining a unique page identity for said page;

(ii) determining a page description for said page, said page description comprising;

(a) a description of said graphical information, and (b) a description of said interactive element, said description of said interactive element including;

(b1) the zone of said interactive element on said page and (b2) an identifier for said interactive element;

(iii) associating said page identity with said description of said interactive element; and

(iv) sending the page identity and the description of said graphical information to said printer, thereby causing the printer to generate the plurality of coded data portions using the page identity and to print the page.

5. The system of claim 2, wherein the graphical information is printed substantially simultaneously with the coded data portions.

6. The system of claim 2, wherein at least some of the graphical information is superimposed with the coded data portions.

7. The system of claim 1, wherein said action provides feedback to a user.

8. The system of claim 1, wherein the code pattern is a dot code.

9. The system of claim 1, wherein the code pattern is substantially invisible.

10. The system of claim 1, wherein said optically imaging sensing device is a handheld pen.

11. The system of claim 10, wherein said pen has a marking nib for marking the printing page.

12. The system of claim 10, wherein said nib is retractable.

13. The system of claim 11, wherein said pen comprises a force sensor coupled to said nib for detecting when said nib is in contact with said page.
