Abstract
An audio player (10) is provided with an image sensor (16) capable of imaging invisible infrared tags (78) on a substrate (70). The tags (78) encode identity data which is directly or indirectly associated in a computer system with one or more audio clips. The audio player (10) can be used to select and play audio clips. It acquires tag identity data via the image sensor (16), transmits it to the computer system, and downloads associated clip(s) for playback via a speaker (22).
Claims10
An audio player including:
- at least one sensor for sensing coded data disposed on or in a substrate, the coded data being indicative of an identity of a description associated with the substrate and of a plurality of positions on the substrate;
- a processor for generating, using the sensed coded data, first indicating data indicative of the identity of the description and of a position of the audio player relative to the substrate;
- a transmitter for transmitting, to a computer system, the first indicating data or second indicating data based at least partially on the first indicating data;
- a receiver for receiving, from the computer system and in accordance with the description, audio data associated with the position of the audio player relative to the substrate;
- and
- at least one audio output device for outputting an audio signal based on the audio data.
