First Claim
1. A handheld display device for displaying and interacting with information corresponding to at least part of a printed substrate, said device comprising:
- an optical sensor for imaging an area of the 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 computer system, thereby causing the computer system to identify the page description and retrieve display data corresponding to at least some of the printed content using the identified page description; and
receiving the display data from the computer system; 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.
