When installed in vehicles that some people would say are already overcrowded with instrumentation, however, could such systems be just one visual distraction too many? Researchers at Carnegie Mellon University and AT&T Labs are addressing that concern, by experimenting with a system that conveys navigational cues through vibrations in the steering wheel. The experimental haptic-feedback-providing steering wheel designed for the project is by no means the first one ever made. Scientists at the University of Utah, for instance, have been testing a wheel that tugs on the skin of the driver’s fingers, indicating which way they should turn. Additionally, various automakers are now offering cars with steering wheels that vibrate to warn drivers of approaching road hazards, or to let them know that they’re drifting out of their lane.
