Patent ID: 8139902

Claim:
A method of conferring interactivity on a pre-printed image containing text, said method comprising the steps of: (i) printing a position-coding pattern onto the pre-printed image, said position-coding pattern identifying a plurality of absolute positions and an impression identity for the image; (ii) scanning the pre-printed image simultaneously with printing the position-coding pattern in step (i); (iii) receiving, in a computer system, association data indicating an association between the impression identity, the plurality of absolute positions and the scanned image; (iv) performing Optical Character Recognition (OCR) on the scanned image to convert text images into computer text; (v) generating an input description for said scanned image, said input description describing words of computer text and zones of corresponding text images in the scanned image; and (vi) storing a page description comprising said input description and said scanned image, said page description being indexed with said impression identity, wherein said page description is retrievable so as to confer interactivity on the image, and wherein the impression identity is initially unassociated with the pre-printed image.
