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.


Data collection and analysis for this student research was completed for 7 male participants (average age 25) from Texas A&M University. All participants reported normal or corrected to normal vision, were familiar with how to text using a smartphone, and had either a valid U.S. or International driver’s license.

Participants completed a primary and secondary task in a medium-fidelity driving simulator. The primary task was driving in either a low or high workload scenario (varied by road configuration an traffic density). The secondary task required participants to read and respond to text messages on either their personal smartphone or Google Glass.

Key Findings:

  • 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.
