Method of displaying hyperlinked information using handheld display device
First Claim
1. A method of displaying hyperlinked information using a handheld display device having an image sensor, a transceiver and an opaque touch-sensitive screen, said method comprising the steps of:
- overlaying said device on part of said printed substrate;
imaging an area of a printed substrate overlain by said device and generating image data using the image sensor, the imaged area of the printed substrate having printed content containing a printed hyperlink embedded in text;
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 at least some of the printed content using the identified page description;
receiving the display data from the computer system;
displaying, on the opaque touch-sensitive screen, display information based on said display data, said display information matching with the printed content underlying said opaque screen, such that the opaque screen has real-time virtual transparency through the screen to the printed content underlying said screen from a user'"'"'s perspective to provide a virtual window to the printed content underlying said screen;
interacting with a displayed hyperlink via said touch-sensitive display screen;
retrieving hyperlinked information corresponding to said hyperlink; and
displaying said hyperlinked information on said screen.

Abstract
A method of displaying hyperlinked information 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 a printed substrate and generating image data using an optical sensor, the printed substrate containing a printed hyperlink; determining interaction data using the image data, the interaction data identifying a substrate identity; retrieving display data corresponding to the substrate; displaying display information based on said display data; interacting with the displayed hyperlink via the touch-sensitive display screen; retrieving hyperlinked information corresponding to the hyperlink; and displaying the hyperlinked information on the screen.
