ZeroTouch – multitouch interface, without the touch

A research team at Texas A&M’s interface ecology lab has come up with ZeroTouch, a multitouch interaction system capable of tracking over 20 individual points, but which requires no actual touch surface. The system, which is based on an array of IR LEDs and IR detectors, is modular and can be mounted around the outside of any display, or can enable so-called free air touch with no surface at all.

The video provides a run-through of the interface, which was demonstrated at the recent CHI event in Canada, as well as showing the free-air potential of ZeroTouch.
