Abstract

A system for providing information is disclosed. The system has a server which stores page descriptors. A printer is also includes which prints a printed page with visible and invisible data. The invisible data is indicative of one or more of the page descriptors. A sensing device senses the invisible data when placed in an operative position relative to the printed page, and transmits information extracted from sensed invisible data to the server. The server is configured to interpret the positioning of the sensing device based upon the page descriptors indicated by sensed invisible data and to provide information associated with the page descriptors.

Dependencies are inferred from the claim text.
