System for providing information to user with every interaction with printed substrate

A system for providing information to a user via a printed substrate. The substrate comprises user information and coded data indicative of a region identity associated with the substrate and of a plurality of locations on the substrate. The system includes an optically imaging sensing device for sensing the coded data and generating interaction data. Receipt of the interaction data by a computer system causes the computer system to identify and retrieve a page description corresponding to the printed substrate and determine whether the sensing device is positioned within a zone.
