Method of Conferring Interactivity on a Pre-printed graphic Image

摘要

A method of conferring interactivity on a pre-printed graphic image. The method comprises the steps of: (i) providing a surface bearing the pre-printed graphic image and an imposed position-coding pattern; (ii) scanning the surface with a scanhead; (iii) imaging a position-coding pattern using an optical sensor; (iv) determining an absolute position from the imaged pattern; (v) determining an impression identity from the pattern; (vi) assembling a scanned graphic image; (vii) generating association data indicating an association between the scanned graphic image, the impression identity and a plurality of absolute positions; and (viii) communicating the association data to a computer system. The computer is can confer interactivity on the graphic image using the association data.
