The sun causes twice as many car accidents as any other weather-related condition due to temporary blindness.* Traditional sun visors block the sun, but also block large areas of the driver’s field-of-view. The Bosch Virtual Visor is an intelligent, hands-free solution to the problem of blinding sun glare. The Virtual Visor replaces the traditional vehicle sun visor with a transparent liquid crystal display. This leads to drastically improved visibility through the display and at the same time automates the adjustments to the visor, leaving the driver to focus on the road ahead of them. The Virtual Visor blocks the sun, not your view!
The Virtual Visor system consists of an interior monitoring camera and transparent LCD. The camera constantly tracks the driver’s face and can intelligently recognize where shadows appear on the face to prevent temporary blindness from sun glare. This requires a visible light imager in order to detect the shadows cast onto the driver’s face. The transparency of the display is continually optimized based on the lighting detected around the driver’s eyes. This maximizes visibility while minimizing strain. *National Highway Traffic Safety Administration, 2008
