Patent ID: 7793824

Claim:
A system for a user to access information, said system comprising: a printed substrate, said substrate comprising user information and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate; and an optically imaging sensing device comprising: an optical sensor for sensing at least some of the coded data when the sensing device is operatively positioned or moved relative to the substrate; a mode selector for allowing the user to select a mode of operation; a processor for generating mode data using the selected mode and interaction data using the sensed coded data, said mode data being indicative of the selected mode, said interaction data being indicative of the region identity and at least one position of the sensing device relative to the substrate; and means for communicating the mode data and the interaction data to a computer system, wherein: the mode data together with the interaction data determine a response in the computer system: the optically imaging sensing device is operable in two or more modes selected from the group consisting of: a hyperlinking mode; a searching mode; a content-extraction mode; a mouse mode; and a handwriting mode; and the hyperlinking mode instructs the computer system to send a hyperlink Uniform Resource Identifier or a corresponding hyperlinked resource to the user, provided that the sensing device is positioned within a zone of a hyperlink on the printed substrate.
