Novel System for 3D Position and Gesture Sensing of Human Hand
Princeton Docket 13-2923-1
Researchers at Princeton University have developed a new touchless 3D gesture and control system for electronic devices including tablets, PCs and smart phones. The system consists of a new hardware device with interfacing software. This novel system has advantages over the current technologies in both accuracy and sensitivity. Princeton is now seeking a commercialization partner to license the technology.
Currently there are three technologies used for 3D bare-hand proximity sensing in industry: camera-based detection, capacitive sensing and infrared sensing. Camera based detection has advantages for long distance detection, but has low performance at close range. It is also difficult for the camera to capture the entire display area. This new sensing technology is able to detect the 3D position of hands at distances from 0cm to 40cm with the same performance at very short distances. It is also able to cover the entire display area. Capacitive sensing has limited distance compared to this new technology. The infrared sensing method is difficult to fabricate into an array for 3D sensing. This new technology is compatible with capacitive touch screen fabrication for sensor array manufacture.
It is anticipated that this method could optimize the current position and gesture sensing control system on electronic devices such as tablets, PCs, and smart phones.
