There's nothing more exciting than new innovations in assistive technology that can help disabled or elderly people live fuller, more independent lives. This particular hands-free device, developed by researchers at Osaka University, is worn on the head like a hairband, with either end equipped with microcomputers and infrared sensors to detect your movements when you press your back teeth together. Pressing the back teeth together in different ways enables the user to send four different types of signals to control electronic devices.
