Abstract
A simulation study compared 36 young adult drivers’ task completion time, eye behavior, and driving performance while dialing a flip-phone with tactile pushbuttons and an iPhone which provides a touch screen interface. Participants who often use a traditional manual button phone completed the dialing task faster when using the flip-phone compared to touch screen users using the iPhone. Females using the flip phone had the highest percentage of time spent with eyes on the road. Females were also less likely to exhibit glances greater than 2 seconds in duration with both phone types and particularly with the flip-phone. Some advantages may exist in a traditional tactile manual interface in terms of the percentage of time drivers kept their eyes on the road.
