A team of scientists has developed a gesture-based way to control your TV. This system uses a controller box with a camera that can recognise simple hand gestures.
Similar to a previous concept developed by MIT, the system works by monitoring the "movements" of a slothful couch surfer, and then reacts to a set of seven hand motions such as clenching your fist ("start"), thumbs-up ("up"), and a sideways peace-sign ("channel"). The researchers say the software can also distinguish between actual "TV gestures" and the movement of pets or small children. In related news, a similar device is also in development which allows its user to control almost all features of your television and associated equipment using a single thumb, although those involved in development are unsure they'll find a market for this "remote," as it were.
Nice but I'm not sure if I'm comfortable with a camera that records all my movements..
