This paper describes the audio component of a virtual reality system that uses remote sensing to free the user from body-mounted tracking equipment. Position information is obtained from a camera and used to constrain a beam-forming microphone array, for far-field speech input, and a two-loudspeaker transaural audio system for rendering 3-D audio.
