The Computational Video Group at NRC-IIT (Canada's National Research Council- Institute for Information Technology) has developed the innovative interface by approaching it from the point of view of face tracking. They've designed a vision-based perceptual user interface to provide a hands-free alternative to a mouse or joystick. Invented by Dmitry Gorodnichy, the trade-marked 'Nouse' with the slogan "use your face as a mouse", uses the motion of the head to control a cursor. Blinking one's eyes takes the place of the left and right mouse buttons.
