ZeroTouch multi-'touch' sensing technology unveiled

Last November, German tech firm Evoluce unveiled a Kinect-based prototype multi-touch system that allows users to navigate through Windows 7 applications, simply by moving their hands in the air. While that system utilizes the Kinect unit’s RGB camera and depth sensor to track the user’s hands, a new technology developed at Texas A&M University's Interface Ecology Lab uses a matrix of infrared light beams to do essentially the same thing. It’s called ZeroTouch, and it was presented at last week’s 2011 Conference on Human Factors in Computing Systems in Vancouver.
