Method of associating audio with a position on a surface
Abstract:
A method of enabling recorded audio to be associated with a location on a surface is provided. The surface has coded data printed thereon, which is indicative of a plurality of locations on the surface. The method comprises the steps of: interacting with the surface using an optical sensing device comprising a microphone; recording audio using the microphone; reading some of the coded data during the interaction; determining a position of the sensing device using the read coded data; and communicating, to a computer system, position data indicative of the position of the sensing device and audio data corresponding to the recorded audio, thereby enabling the computer system to associate the audio data with the position.
