Abstract

A system for electronically capturing information is disclosed. The system includes a user input device movable by a user relative to a first interface surface provided on a first document. The first interface surface has visual information and coded data disposed thereon. The coded data encodes an identity of the first document and coordinates of a plurality of locations of the first interface surface. The user input device includes an image sensor for sensing at least some of the coded data and for generating movement data from the coordinates encoded in sensed coded data. The system further includes a computer system arranged to receive the movement data from the user input device and for generating print data in response to the movement data. The system also includes a printer for receiving the print data from the computer system and for printing a second document using the print data. The second document is printed with a second interface surface thereon. The second interface surface has visual information and coded data disposed thereon. The coded data again encodes an identity of the second document and coordinates of a plurality of locations of the second interface surface.

Claims

1. A system for electronically capturing information, the system comprising:

a user input device movable by a user relative to a first interface surface provided on a first document, the first interface surface having visual information and coded data disposed thereon, the coded data encoding an identity of the first document and coordinates of a plurality of locations of the first interface surface, the user input device comprising an image sensor for sensing at least some of the coded data and for generating movement data from the coordinates encoded in sensed coded data; and

a computer system arranged to receive said movement data from said user input device and for generating print data in response to the movement data; and

a printer for receiving the print data from the computer system and for printing a second document using the print data, the second document being printed with a second interface surface thereon, the second interface surface having visual information and coded data disposed thereon, the coded data encoding an identity of the second document and coordinates of a plurality of locations of the second interface surface.

2. A system according to claim 1, wherein the coded data is in the form of a plurality of tags printed upon the first and second interface surfaces.

3. A system according to claim 2, wherein each tag encodes the identity of the first or second document and its own location on the first or second interface surface.

4. A system according to claim 1, wherein the printer is configured to print the coded data in infrared absorptive ink at the same time as printing the visual information of the second interface surface.

5. A system according to claim 1, wherein the movement data is indicative of a plurality of time stamped coordinates on the first interface surface.

6. A system according to claim 1, wherein the user input device further comprises a nib and a force sensor for detecting contact of the nib with the first interface surface.

7. A system according to claim 6, wherein the image sensor senses the coded data when the force sensor detects contact of the nib with the first interface surface.

8. A system according to claim 6, wherein the user input device further decodes the coded data to generate data relating to the position and orientation of the input device relative to the first interface surface.

9. A system according to claim 8, wherein said data relating to the position and orientation of the instrument relative to said surface is captured as a series of one or more strokes.

10. A system according to claim 9, wherein each stroke is a sequence of time-stamped positions of said instrument initiated by initial contact of said nib of the input device with said first interface surface and completed by removal of said contact between the nib and the first interface surface.

11. A system according to claim 1, wherein the computer system comprises a document server which stores document data relating to a plurality of documents, said document data including the visual information on each document together with the location of the visual information relative to one or more interface surfaces of the document.

12. A system according to claim 11, wherein upon receiving said movement data from said input device, the computer system retrieves the document data relating to the first document from the document server and determines which element of the first document the movement data relates to.

13. A system according to claim 12, wherein upon determining which element of the first document the received movement data relates to, said computer system interprets said movement data in the context of the element to generate the print data.
