Patent ID: 7148499

Claim:
A device for interacting with an interface surface provided on a substrate, the interface surface including coded data disposed therein or thereon, the device including: at least one sensor for sensing at least some of the coded data; a processor for generating, using the sensed coded data, first data, the first data being at least partially indicative of: an identity of the interface surface; and, a position of the device relative to the interface surface; a transmitter for transmitting the first data to a computer system, the computer system being responsive to the first data to: determine, using first data, a page description; and, determine, using the page description and the position, display data at least partially indicative of information; a receiver for receiving, from the computer system, the display data; and, at least one display device for presenting, using the display data, the information, wherein the device is configured and arranged such that the sensor is operative to sense the coded data when the display device is positioned, in use, at least partly overlapping the substrate.
