Driving Behavior Monitoring with Unobtrusive Smart-glasses

Distracted driving is a major cause of road accidents. Multiple targets, including the driver's head and two hands, need to be monitored to detect unsafe driving behaviors. Previous driving monitoring systems rely on cameras or wearable sensors, yet these solutions have multiple limitations, including insufficient monitoring or requiring multiple wearable components. This paper proposes a new driving behavior monitoring system for improving road safety, which achieves unsafe driving behavior monitoring using only one pair of unobtrusive Commercial-Off-The-Shelf (COTS) smart glasses. The proposed system monitors the two hand movements using the front-facing camera, and detects head movements using the onboard sensors. A proof-of-concept system was implemented on a pair of Android-powered smart glasses, and a small-scale emulation study was conducted in the lab environment. Experiments show our system can monitor steering wheel control techniques and common head turn motions with f1 scores of 93.1% and 99%, respectively.
