Abstract

Position information is input into an information processing system in, e.g. a mobile communication terminal (301). The system comprises a plurality of microphones (302) located at known microphone positions and connected to processing circuitry capable of interpreting sound signals from the microphones (302). A sound signal, is received from each microphone, the signals originating from an acoustic wave emanating from an acoustic sound source located at a first position (306). A respective difference in distance between the sound source at said first position and respective microphone is then calculated, followed by a calculation, using a geometric model, of an estimate of said first position, said estimate being position information intended for use in the information processing system.
