Artificial Intelligence in your Sun Visor

Sun visors in motor vehicles have been around since the 1920s. Recently, Bosch decided that it was time to upgrade the design and technology of sun visors that have remained virtually unchanged since their inception. What they have come up with is known as the “Virtual Visor.” Bosch states that the idea behind the Virtual Visor is to reduce sun glare, which can impair the driver’s ability to see clearly while driving.

The technology is a transparent liquid crystal display (LCD) panel comprised of hexagonal pixels in a honeycomb grid. The transparent screen is used with an RGB camera inside the vehicle that tracks where the sun is coming from and where it shines on the driver’s face. Together, the LCD screen and RGB camera can track the driver’s face, track moving shadows, and track sunlight. Artificial intelligence takes these data and uses an algorithm to identify exactly where the driver’s eyes are. According to Bosch engineers, this algorithm was the most challenging piece of the technology. They wanted the algorithm to be able to do all of the tasks listed above – identify the driver’s face, track moving shadows, and locate which direction the sun was coming from – and then use that to constantly and accurately update the location and degree of shade of the Visual Visor. AI should ideally be able to provide relief from sun glare by casting shade directly over the driver’s eyes, Bosch says.

Bosch claims that one of the advantages to the Virtual Visor includes reduced sun glare and better visibility as drivers will be able to see through the visor even as it provides shade. In other words, Bosch believes that with the Virtual Visor, drivers would no longer block a portion of their view in order to get relief from the sun while driving.
