First Claim
1. A system for retrieving display data, said system comprising:
- (A) a handheld display device comprising;
an optical sensor for imaging an area of a printed substrate containing printed content and for generating image data;
a processor for determining interaction data using the image data, said interaction data identifying a page description corresponding to the printed substrate;
a transceiver for sending the interaction data to a server and receiving the display data from the server; and
a touch-sensitive screen for displaying display-information based on said display data, said touch-sensitive screen enabling user interaction with the display-information; and
(B) a server configured for;
receiving the interaction data from the handheld display device;
identifying the page description corresponding to the interaction data;
retrieving the display data using the identified page description, said display data corresponding to at least some of the printed content imaged by the device; and
