To crack these problems and increase the system’s usefulness, GM’s Research and Development, Carnegie Mellon, The University of Southern California and several other institutions are working together to create a new HUD dubbed the “Enhanced Vision System.” While older HUDs use special glass to reflect lights in an in-dash display toward the driver, this new system draws the display directly by shooting ultraviolet lasers at a photoreactive coating on the windshield.
The Enhanced Vision System does a lot more than display information from the dash. Boundary lines for roadways and lanes can be drawn onto the glass, aiding drivers in foggy and dark conditions. GPS information is also integrated into the system, identifying routes by drawing them directly in view of the road. Once the destination is in view, the system can draw a circle around the location.
