GM Develops Augmented Reality Windshield

The entire windshield is turned into a transparent display to highlighting landmarks, obstacles and road edges on the windshield in real-time. Such a system can point out to drivers potential hazards, such as a running animal, even in foggy or dark conditions, GM says. GM uses a special type of glass coated with red-emitting and blue-emitting phosphors--a clear synthetic material that glows when it is excited by ultraviolet light. The phosphor display, created by SuperImaging, is activated by tiny, ultraviolet lasers bouncing off mirrors bundled near the windshield. Three cameras track a driver's head and eyes to determine where she is looking. [Via Technology Review]
