New Input Interface by Tokyo University can capture fingers movement

Professor Masatoshi Ishikawa and Dr. Takashi Komuro of the Tokyo University has developed a new input interface called 'vision-based Input Interface'. The device developed by Tokyo University team can translate in-air movements of fingers to computer command, which enables you to use portable devices without even a touch. To catch finger movement, the device adopted 154 frame per second high-speed camera. Usually two lenses are used to detect 3D movement but customized softwares enables camera to detect them with only one lens. (source)
