Abstract
A system for providing information to a user via a printed substrate. The system includes the printed substrate, an optically imaging pen device and a display device. The optically imaging pen device is configured for reading coded data from the substrate; generating interaction data using the coded data; and sending the interaction data to a computer system. Receipt of the interaction data by the computer system causes the computer system to: identify and retrieve a page description corresponding to the printed substrate; generate a query expression including one or more search terms; form a request using the query expression; and send the request to the display device.
