Effects of sleep deprivation on eye movement behavior in flight simulation

摘要：

　　To examine the effects of 32 h of SD(sleep deprivation) on eye movement behavior in flight task.Four subject who were skilled in flight simulator participated the experiment.They were asked to perform a level flight task in a flight simulator.Eye movement data and flight performance data were measured at the following hours: 11:00,15:00,04:00,11:00,15:00.The subjects workload and fatigue were assessed with method of NASA-TLX(national aeronautics and space administration-task load index) and RPE(rating of perceived exertion).Eye movement indices of average pupil area,average saccade amplitude and average saccade velocity decreased during the 32 h SD and they all showed significantly change in the final SD while the index of average fixation time increased in the final SD.Flight performance deteriorated during the 32 h SD,but not significantly.The feeling of fatigue and workload reported by subjects both increased during the 32 h SD.Daily rhythm effects on the measured indices were also found,there were a obviously change at the hour of 04:00.32 h of SD has obvious effects on eye movement behaviors which have close relations to fatigue because of SD.The eye movement measurement can served as a tool to continually monitor fatigue online.
