Eye-Activity Measures of Fatigue and Napping as a Fatigue Countermeasure
Eye-Activity Measures of Fatigue and Napping as a Fatigue Countermeasure
This study investigated the potential use of an eye tracking system for detecting reduced driver alertness, and the impact of prophylactic napping on driver performance and alertness. The study used traditional behavioral and physiological measures of alertness. In addition, an unobtrusive eye tracker attached to the simulator structure was used to measure eye and eyelid behavior. The results showed clear time-of-day (TOD) and time-on-task (TOT) effects for the following eye closure measures: Partial closures during fixations, speed or slow eyelid closure (SEC), blink duration, and blink frequency.
