METHOD OF PLAYING AND CONTROLLING AUDIO USING HANDHELD DISPLAY DEVICE
First Claim
1. A method of controlling audio playback using a handheld display device having an image sensor, a transceiver and a touch-sensitive screen, said method comprising the steps of:
- imaging an area of a printed substrate and generating image data using the image sensor, said printed substrate containing printed content associated with audio;
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 audio data associated with said printed content;
receiving the audio data from the computer system;
displaying, on said touch-sensitive screen, display information identifying said audio together with at least one static element for controlling audio playback; and
controlling audio playback by interacting with said at least one static element via said touch-sensitive screen.

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