Acoustic sensors make surfaces interactive

Researchers in Europe have come up with Tai-Chi, or (Tangible Acoustic Interfaces for Computer-Human Interaction), that are a series of acoustic sensors that turn any surface into a touch-sensitive computer interface. The system uses sonar tracking that senses surface vibrations and can track up to two things at once. This could be very useful in the work place like hospitals that are concerned about hygiene, because the clean up would be non-existent. It could also be used as a data input interface in almost every computer.
