How to draw pictures in midair
May 11, 2011
A unique optical multitouch sensing technology using infrared sensors has been developed by researchers at the Interface Ecology Lab at Texas A&M University.
ZeroTouch allows users to literally draw pictures in midair. It provides zero-force, zero-thickness, high-frame-rate, high-resolution, transparent multitouch sensing.
ZeroTouch’s new forms of free-air interaction are more precise than the Microsoft Kinect, the researchers said.
ZeroTouch was demonstrated at the recent ACM Conference on Human Factors in Computing Systems in Vancouver, B.C.
