Different vehicles have the same basic system of shade, and the sun visor can help prevent direct sunlight from the driver. It is well known that the sun visor is a flippable solid part that blocks the eyes and sometimes does not have an obvious effect. Researchers at Bosch say solar glare causes thousands of car accidents each year, almost twice as many as any other weather condition.
The virtual sun visor developed by Bosch is a transparent LCD display with a driver-oriented camera, AI facial detection and analysis, and tracking software that completely replaces the traditional sun visor. The technology can visually block the sun’s glare without blocking the view of the road ahead. Bosch points out that this virtual sun visor won the CES 2020 Best Innovation Award. The system uses the camera and AI to locate the driver in the image. It also uses AI to identify faces to find out where the eyes, nose and mouth are.
The system only darkens the part of the display that lets light shine on the driver’s eyes. The rest of the screen will remain transparent to prevent blocking the driver’s field of view. The team said they learned early in development that users would adjust traditional sun visors to cast shadows on their eyes. This understanding is of profound significance in helping teams simplify concepts and drive technical design. It is unclear whether the virtual sun visor will be commercialized and when the technology will enter the car market.
