"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 lead author William Provancher, an assistant professor of mechanical engineering at the University of Utah.

He adds that the study was based on a "multiple resource model" of how people process information, where our senses are considered resources that relay information to our brains
