Apple Patent Featuring Sound Based Commands

 

Another new Apple Patent is showing that the company wants another way to input commands. In the patent you could swirl your finger over a specific area or scratch and this would drive a certain command on the device. The patent outlines that this could be done by listening in to the housing itself or just keeping an electronic ear listening to the sounds of touching the surface. This probably wont be in any new products anytime, and this is probably just is research.
