New gadget that controls a car's functions with just a wink or a nod of the driver's head

New gadget that controls a car's functions with just a wink or a nod of the driver's head: "Engineers have come up with a whole new way driving using just facial expressions after creating a gadget that controls a car's functions using nods and winks. The infra-red sensor is mounted on the dash board and recognises the driver's facial expression to control the car. A computer concealed inside the car translates the gestures which corresponds to a list of commands for the radio, Sat Nav, heating and mobile phone."
