Since the dawn of driving, there's been an annoying constant sun glare. Early commuters squinted and used gloved hands to hide the blinding rays of the sun, at least until about 95 years ago when the first sun visor came up with some brilliance. Nearly a century later, modern automobiles are more sophisticated and capable orders of magnitude, and we continue to use the simple simplistic board-on-a-hinge design to avoid being blinded by the sun. The Virtual Visor from German supplier Bosch can be just the high-tech solution that modern drivers need to cut through the glare.

The Bosch Virtual Visor, which debuted at CES this week, features a transparent LCD screen paired with a small RGB camera in cabin used to monitor the sun shining on the driver's face. To track shadows as they pass across the driver's face, the device uses artificial intelligence to identify facial features (including eyes, mouth, and nose).

To order to avoid blindness, a proprietary algorithm is then used to classify where the driver's eyes are and selectively block and unblock (dark) portions of the Virtual Visor. Main advantage? 90 percent of the visor remains visible at all times, so the driver can still see it much more easily than a traditional fabric-covered viewfinder would.
