Glasses Double Up As GPS Navigation System
LEDs and a magnetic direction sensor make up a simple and unobtrusive wayfinding solution.
One of the highlights of the Wireless Japan 2010 was the Wearable Personal Navigation System developed by the Nakajima Laboratory of the University of Electro-Communications. This GPS-equipped pair of glasses has in-built LEDs in the frame and a magnetic direction sensor, so whenever a user points his face in a certain direction, the LEDs change color to indicate which way he needs to head to.
