Blinding glare and bright spots from high-lumen sources pose a hazard and nuisance for drivers. Existing solutions to glare control include opaque sun visors and tinted/polarized glass. These solutions have drawbacks. Tinted and polarized glass darken both bright and dim viewing areas, causing potential low visibility hazards for dimmer areas. Traditional auto visors shade the sun by blocking the rays, which can be a safety hazard as this also impedes the driver’s line of sight.

Researchers at UAH have developed a Brightness Limiting System (BLiS) which marries commercially available displays with light detection and filtering technology. BLiS would function as an automatic, dynamic shade that would dim only the portion of the display containing the offending light source.

BLiS can be created using commercial off-the-shelf (COTS) hardware, making it cost effective. The BLiS light-filtering process would be instantaneous, providing an additional safety feature currently not available to drivers.
