Patent ID: 7941338

Claim:
A method of enabling a user to request further information from an interactive document printed on a substrate, said method comprising the steps of: (a) receiving a print instruction for printing the interactive document; (b) allocating and recording a unique document identity for the document in a computer system in response to receiving the print instruction such that every printed copy of the document has a different document identity allocated thereto; (c) determining a map of the document and associating said map with the allocated document identity in the computer system, said map including a description of at least one interactive zone of the document; (d) sending the allocated document identity to a printer networked with the computer system; (e) generating in the printer, using the received document identity, data content for a plurality of tags; (f) printing the document onto a substrate and at the same time printing the plurality of coded data tags onto the substrate each tag containing coded data indicative of the document identity and its own location on the substrate; (g) receiving, in the computer system, indicating data from a sensing device, said indicating data comprising data regarding the identity of the document and a position of the sensing device relative to the document, the sensing device when placed in an operative position relative to the document generating the indicating data using the coded data; (h) identifying in the computer system, using the indicating data and the recorded document identity, at least one parameter relating to the request; and (i) providing the requested information to the user, wherein the map of the document is associated with the document identity before printing of the document by the printer.
