Automakers may promote voice-activated technologies as a
safe, hands-free way of checking e-mail and Facebook while driving, but a new
study from the AAA Foundation for Traffic Safety shows that these technologies
are actually more distracting to drivers than cell phones. Although users of
voice-activated technologies can keep their hands on the wheel and eyes on the
road, the study reveals an increased mental workload when using those
technologies when compared with cell phone use and other activities.
A research team at the University of Utah led by cognitive
distraction expert Dr. David Strayer measured brainwaves, eye movement and
other metrics to assess the impact of various activities on a driver’s
concentration. The team used the results to rate the levels of mental
distraction experienced by drivers performing each of several tasks:
- Listening to the radio ranked as category “1” with a minimal risk level.
- Talking on a cell phone, whether handheld or hands-free, ranked category “2”, or a moderate risk.
- Listening and responding to in-vehicle, voice-activated email features put drivers at a category “3” ranking with extensive risk.
Based on this research, AAA has the following
recommendations for the automotive and electronics industries:
- Limit use of voice-activated technology to driving-related activities like windshield wipers and cruise control.
- Disable functionalities of voice-to-text technologies such as using social media or e-mail so that they are inoperable while the vehicle is moving.
- Educate vehicle owners and mobile device users about safety risks for in-vehicle technologies.
