ABSTRACT:
A handheld display device for displaying and interacting with information corresponding to a printed substrate. The device comprises: a transceiver for sending and receiving digital information; 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; and a touch-sensitive screen for displaying display information based on retrieved display data. The touch-sensitive screen enables user interaction with the display information.
