Head-up displays like Google Glass were made to assist drivers in multitasking. Rather than reaching for a phone to manually send or receive a text, a driver using Google Glass would be able to read projected messages and dictate replies without ever having to take their hands off the wheel. The concept seems logical to most, yet groups like the Consumers Union and the National Safety Council have cautioned that hands-free, voice-based interfaces can still pose as a dangerous distraction to drivers.
According to a Forbes article published yesterday, a peer-reviewed study conducted by the University of Central Florida in partnership with the Air Force Research Laboratory compared 40-something drivers in a car simulator while wearing the Google Glasses, and their responses to when the vehicle driving in front of them suddenly slammed on the brakes. Researchers found that subjects who had been exchanging messages using Google Glass or a smartphone were just as equally slow to respond. Wearers of the Google Glass did appear to recover more quickly after the near crash, but they also left less distance between the car they were operating, and the car in front of them. This data suggested that the Google Glass reduced participants’ perception to risk.
In a similar study conducted at Wichita State University, researchers found while comparing speech-based texting to handheld texting, there was no significant difference in driver performance. “In fact, the researchers found that both methods of texting significantly impaired driver performance and caused variation in speed and lane position.”
