Abstract: A method of playing audio data by a portable device is disclosed. The method starts with an optical sensor of the portable device sensing a tag on a surface. The tag encodes an identity of the surface and a location of the tag on the surface. Audio data is recorded by an audio system of the portable device. A processor of the portable device determines the identity of the surface and the location of the tag sensed by the optical sensing device on the surface. The portable device communicates the audio data, the identity of the surface and the location of the tag to a computer system where the audio data is associated with the identity of the surface and the location of the tag. Upon subsequent sensing of the tag by the optical sensor, the portable device communicates the identity of the surface and the location of the tag to the computer system, where the audio data associated with the identity of the surface and the location of the tag is retrieved and communicated to the portable device.
