Acoustic sensors make surfaces interactive
Interactive Systems Research Group, Reading University, UK
A series of acoustic sensors that turn any surface into a touch-sensitive computer interface have been developed by European researchers.
Two or more sensors are attached around the edges of the surface. These pinpoint the position of a finger, or another touching object, by tracking minute vibrations. This allows them to create a virtual touchpad, or keyboard, on any table or wall.
