GPS Navigation System Built into Eyeglasses

From Neatorama:

At a recent trade show, the Nakajima Lab at the University of Electro-Communications in Tokyo demonstrated a prototype GPS directional system that is built into a pair of glasses. The user starts by inputting his/her destination, then following lights in the frame indicating which direction in which to travel. The Nakajima Lab says that this system could be safer than handheld GPS guidance systems because the user can keep his/her eyes on the road.
