Patent ID: 7821507

Claim:
A method of enabling a user to initiate an action via a printed substrate, said substrate comprising user information and coded data, said coded data being indicative of a region identity associated with the substrate and of a plurality of locations on the substrate, said method comprising the steps of: receiving, in a computer system and from an optically imaging pen, mode data and interaction data, the pen being operable in a plurality of modes and the mode data being indicative of one of said modes, the interaction data being indicative of the region identity and at least one position of the pen relative to the substrate, the pen generating the interaction data, when operatively positioned or moved relative to the substrate, by reading at least some of the coded data; identifying and retrieving at least part of a page description corresponding to the printed substrate using the region identity; determining a mode of the pen using the mode data; and initiating an action using said mode, said interaction data and said page description, wherein: said mode is selected from the group consisting of: a hyperlinking mode; a searching mode; a content-extraction mode; a mouse mode; and a handwriting mode; said pen in operable in two or more of said modes; and said action is selected from the group consisting of: hyperlinking, searching, content-extraction, cursor control and handwriting input.
