Head-up displays are becoming common in new vehicles — but now they’re getting more advanced. Israeli startup Spectralics and Envisics of the U.K. are among the players developing ways to enhance head-up displays with augmented reality technology. A Spectralics system uses a thin optical film layered over a vehicle’s windshield to display images, safety alerts, navigation prompts and other notifications. Volvo has invested in the supplier. The technology “opens up new possibilities to create a more immersive experience,” Michael Schön, technology lead at Volvo Cars’ R&D Open Innovation Arena, told Automotive News.
