A vibrating steering wheel is being designed by two Nevada scientists that will tell drivers where to steer when undipped headlights or other visual impediments leave them temporarily blinded.
Eelke Folmer and Burkay Sucu at the University of Reno in Nevada, believe that the steering wheel may help cut the accident toll caused by glare, especially in winter, when motorists are most likely to be dazzled by low sun and reflections from snow and ice.
AdvertisementThe system relies on car sensors like GPS and lane-keeping cameras to map the road ahead and work out where the vehicle is. When sensors detect the driver may be dazzled and drifting from their lane, the vibro-tactile system buzzes into action.
The vibrations are tuned to 275 hertz, the frequency that our skin is most sensitive to. And the cues are directional, so if a driver drifts left, the left side of the wheel will vibrate - a signal to steer right until it stops vibrating, just like a rumble strip.
