With surveys showing that three out of four drivers believe hands-free technology is safe to use, “Americans may be surprised to learn that these popular new vehicle features may actually increase mental distraction,” the AAA Foundation for Traffic Safety said…

Tuesday (http://bit.ly/1nc22fb). New research it commissioned suggests developers “can improve the safety of their products by making them less complicated, more accurate and generally easier to use,” it said. “While manufacturers continue their efforts to develop and refine systems that reduce distractions, AAA encourages drivers to minimize cognitive distraction by limiting the use of most voice-based technologies.” Using specialized equipment designed to measure reaction times, University of Utah researchers “evaluated and ranked common voice-activated interactions based on the level of cognitive distraction generated,” it said. The research team used a five-category rating system, similar to the scale used for ranking hurricanes’ strength, it said. It found the accuracy of voice recognition software “significantly influences the rate of distraction,” it said. Systems with low accuracy and reliability generated a high level (category 3) of distraction, it said. Composing text messages and emails using in-vehicle technologies (category 3) was more distracting than using these systems to listen to messages (category 2), it said. “The quality of the systems’ voice had no impact on distraction levels -- listening to a natural or synthetic voice both rated as a category 2 level of distraction."
