GM is developing Enhanced Vision System, a new technology that turns your car's windshield into an augmented reality display. The system uses front-facing sensors and some cameras, and is capable of painting road lines on the windshield, it reads road-side signs to help with navigation, and helps you avoid obstacles and animals at night.
The Enhanced Vision System is designed with safety in mind just like previous implementations, but takes it to a whole new level. Let’s say it’s foggy or stormy. Ultraviolet lasers will paint road lines on the windshield and even read road-side signs to aid with navigation. An enhanced night vision mode even works with the new system to more percisouly identify road obstacles and animals.
All this is done with a series of front-facing sensors. This is combined with several in-vehicle cameras that track the drivers head and eyes to properly place the augmented reality layer on the windshield.
