Anti-Glare Active GlassesBenoist FLEURY

According to a recent survey conducted in France and Germany*,car drivers consider that the most disturbing situation while driving a car isbeing dazzled by the headlamps of oncoming cars. Indeed, whatever the qualityof the headlamps and the attention paid by set-makers to minimize the dazzlinglight above the cut-off, the age and the tiredness of the driver or a rainy environmentcan make a succession of crossed headlamps an unbearable driving experience. Inaddition of the discomfort it generates, safety is at stake: who has neverdesperately whished no pedestrian is passing by while crossing a glaring car? The solution we propose to describe offers to reduce thebrightness of all light sources but the headlamps of its own car. Based on thesynchronization of a pair of active glasses with pulsed led-based headlamps,the system divides by 4 the ratio of perceived intensity of adverse glaringsources / road illumination. In addition to prevent from being glared at night, theseactive glasses are also capable of reacting instantly to ambient light atdaytime. Would you drive by a sunny day and enter a tunnel, the glasses switchinstantly from a tinted state to a transparent state, coming back instantly tothe adequate tinted state when exiting the tunnel. Comprehensive videos will be used during the talk to illustratethe use cases and demonstrate the benefit of the system while a functionalprototype will be exhibited.
