Touch-based directional devices let users feel directions

In-car navigation systems that literally tell drivers where to go are much more convenient and safer than resting a street directory on one’s lap and quickly trying to devise a route on a map at a set of traffic lights. But audio instructions may not always be the best way to impart directional information to hard of hearing drivers or those yakking on a mobile phone – with a hands-free kit I should hope. A new study suggests that devices mounted to a steering wheel that pull the driver’s index fingertips left or right could help motorists drive more safely. The same technology could also be attached to a cane to provide directional cues to blind pedestrians.
