HANDHELD DISPLAY DEVICE FOR REVEALING HIDDEN CONTENT ON A PRINTED SUBSTRATE
First Claim
1. A handheld display device for imaging a printed substrate and revealing hidden content associated with the 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 comprising first data corresponding to said printed content and second data corresponding to the hidden content; and
receiving the display data from the computer system; and
a touch-sensitive display screen for displaying display information based on said display data, said display information including first content corresponding to the printed content and second content corresponding to the hidden content, thereby revealing the hidden content on said screen.

Abstract
A handheld display device for imaging a printed substrate and revealing hidden content associated with the printed substrate. The device comprises: an optical sensor for imaging an area of the printed substrate and for generating image data; a processor for determining interaction data using the image data, the interaction data identifying a substrate identity; a transceiver for retrieval of display data corresponding to the printed substrate, the display data comprising first data corresponding to the printed content and second data corresponding to the hidden content; and a touch-sensitive display screen for displaying display information based on the display data. The display information includes first content corresponding to the printed content and second content corresponding to the hidden content, thereby revealing the hidden content on the screen.
