Anyone whose been to the cinema knows it’s possible to create an artificial, high-precision, 3-D stereo sound field. Now imagine equipping a room with a bank of speakers which generate a sound field corresponding to that which might created by a single noisy insect moving around inside.
This acoustic point source could be made to appear to move about a room, or within a vehicle, allowing someone to follow the sound as if following a real insect.
This might be used to help direct people around a predetermined circuit. It might work as a replacement for the voice in satnav systems, for example. By simply driving towards the noise of the virtual insect (as created in realtime by the car’s sound system).
