Verbal directions given by GPS navigation systems can be hard to hear in a noisy car. That's why researchers at the University of Utah are developing a navigation system that communicates driving directions through a tactile interface:
The researchers say they don't want their results to encourage dangerous and distracted driving by cell phone users. Instead, they hope the study will point to new touch-based directional devices to help motorists and hearing-impaired people drive more safely. The same technology also could help blind pedestrians with a cane that provides directional cues to the person's thumb.
"It has the potential of being a safer way of doing what's already being done – delivering information that people are already getting with in-car GPS navigation systems," says the study's lead author, William Provancher, an assistant professor of mechanical engineering at the University of Utah.
