Apple could be working on AR displays for its upcoming autonomous cars. A patent application by the Cupertino giant reveals details about an AR system that's designed to present 3D models of the road ahead on the windshield. Apple Insider reported Thursday that it has spotted a new patent application by Apple, entitled "Adaptive Vehicle Augmented Reality Display Using Stereographic Imagery." In the documentation that the U.S. Patent & Trademark Office published late last week, it is stated there that Apple is thinking of an AR system that generates imagery of sceneries based on a pre-generated 3D model of the world. According to the Apple-centric news site, the patent could be hinting at an AR display for the upcoming Project Titan car. The possible purpose of having the AR system around is to provide the autonomous vehicle with information about the road ahead, including things that may be out of the driver's vision.
