METHOD OF MAGNIFYING PRINTED INFORMATION USING HANDHELD DISPLAY DEVICE
First Claim
1. A method of magnifying printed content using a handheld display device having an image sensor, a transceiver and a touch-sensitive screen, said method comprising the steps of:
- imaging an area of a printed substrate containing printed content and generating image data using the image sensor;
determining interaction data using said image data, said interaction data identifying a page description corresponding to the printed substrate;
sending the interaction data to a computer system, thereby causing the computer system to identify the page description and retrieve display data corresponding to the printed content using the identified page description;
receiving the display data from the computer system;
displaying, on said touch-sensitive screen, display information based on said display data, said display information including displayed content corresponding to the printed content;
interacting with the displayed content via said touch-sensitive screen,wherein said interacting via said touch-sensitive screen magnifies the displayed content on said screen.

Abstract
A method of magnifying printed content using a handheld display device having a touch-sensitive screen and a transceiver for sending and receiving digital information, The method comprises the steps of: imaging an area of the substrate containing printed content and generating image data using an optical sensor; determining interaction data using the image data, the interaction data identifying a substrate identity; retrieving, using the interaction data and the page description, display data corresponding to the printed content; displaying, on the touch-sensitive screen, display information based on the display data, the display information including displayed content corresponding to the printed content; and interacting with the displayed content via the touch-sensitive screen. Interacting with the displayed content via the touch-sensitive screen magnifies the displayed content on the screen.
