If you are under the assumption that hands-free texting is safer than manual texting, think again. A recent study published by AAA found that using voice-to-text devices are extremely dangerous and mentally distracting despite the fact that they are hands free.
The study comes in wake of a new projected five-fold increase of vehicles with elaborate infotainment systems, by 2018. With more and more cars with “smart” technology joining the road today, AAA is requesting its research be taken into consideration by car and tech manufacturers.
“It’s time to consider limiting new and potentially dangerous mental distractions built into cars, particularly with the common misperception that hands-free means risk-free,” Lloyd P. Albert, AAA Southern New England Senior Vice President of Public and Government Affairs said.
AAA’s study, which was conducted at the University of Utah, found that as these mental distractions increase:
• Reaction time slows • Brain function is compromised • Drivers scan the road less and miss visual cues, which may result in drivers missing objects in front of them such as pedestrians, or running stop signs and traffic signals.
Dr. David Strayer, a cognitive distraction expert at the University of Utah, and his research team, measured brainwaves and eye movements of drivers to evaluate the effects of multitasking and using devices while driving on mental workloads. The team conducted a series of tests and used cameras inside an instrumented car to track drivers’ eye movements, detection-response-task (DRT) devices to record driver responses, as well as a special electroencephalographic (EEG)-configured skull cap to measure brain activity so that researchers could determine drivers’ mental workloads.
Subjects performed a series of tasks while driving including, listening to the radio, talking on the cell phone (both handheld and hands-free) and listening and responding to in-vehicle, voice-activated email features, and researchers rated these tasks on a scale of 1 to 5 (with 5 being the highest level of distraction). Researchers concluded that listening to the radio ranked as a category “1” level distraction or minimal risk. Talking on a cell-phone or passenger in a car ranked in category “2” and posed moderate risks.
