In-vehicle driver distractions are an increasing cause of automobile accidents. Recent advances in wearable consumer technologies impose new challenges for managing driver attention and regulating device use in the driving context. Google Glass is a wearable interface that presents information via a heads-up display and read aloud function, neither of which obstructs the user’s view of the surrounding environment. While Glass may benefit drivers by providing driving-related notifications, no documentation exists objectively measuring the extent to which using Glass impacts driving performance and safety. This preliminary study compared texting with Google Glass to other texting methods in a driving simulation to examine driver behavior and performance. While texting-and-driving is inadvisable, the task of texting may be constructed so that it does not provide information that alters the intent of the driving task, reducing confounding factors in analysis of the device’s impact on driving performance. The results of this study suggest that Glass performs much closer to baseline than the other technologies. Evidence from this preliminary investigation was used to form a complete study evaluating texting-and-driving with Google Glass. Results from these studies can be used to inform developers of wearable technologies and policymakers tasked with regulating the use of these technologies while driving. (Author/publisher)
