Abstract
An acoustic user interface apparatus and method can detect physical touch contacting a sensing surface and improve the accuracy of direction recognition of a touch or rubbing without any complicated algorithm. The user interface apparatus and method use one microphone to detect and analyze sound waves which are generated by collisions between bumps formed in a top plate or bottom plate of the interface apparatus and the opposing bottom plate or top plate when a user is touching or rubbing the sensing surface.
