Method of playing and controlling video using handheld display device

摘要

A method of controlling video playback 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 printed content associated with a video; determining interaction data using the image data, the interaction data identifying a substrate identity; retrieving video data associated with the printed content; displaying, on the touch-sensitive screen, the video or display information identifying the video together with a static element for controlling video playback; and controlling video playback by interacting with the static element via the touch-sensitive screen.
