A shoulder-mounted camera system that automatically tracks head movements and can recognise hand gestures has been developed by UK researchers. Eventually, they hope the system could identify a wearer's activity and offer assistance, for example by accessing a telephone directory when they reach for the phone.
The collar-mounted camera is worn on one shoulder. It is controlled wirelessly from a laptop computer, which uses the camera's output to keep track of objects, map its position and recognise different hand gestures made by the user. Walterio Mayol Cuevas, now a researcher at Bristol University, UK, created the camera while working at the University of Oxford.Three separate motors make the camera highly directional, and even allow it to tilt, while inertia sensors are used to keep it pointed correctly while the wearer moves around
