Handheld display device for playing video associated with printed substrate

摘要

A handheld display device for imaging a printed substrate and playing video 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 video data corresponding to the printed substrate; and a touch-sensitive display screen for playing the video based on the video data.
