A vibrating steering wheel is an effective way to keep a driver's eyes safely on the road by providing an additional means to convey directions from a car's navigation system, researchers at Carnegie Mellon University and AT&T Labs have shown. The study, one of the first to evaluate combinations of audio, visual and haptic feedback for route guidance, found that younger drivers in particular were less distracted by a navigation system's display screen when they received haptic feedback from the vibrating steering wheel.
