Abstract:
Objective To investigate the eye movement difference in orientation mission simulation between experienced pilots and novice pilots.Methods Thirty pilot subjects were divided into experienced group (flying hours ≥ 1000 h) and novice group (flying hours ≤300 h) and completed the spatial orientation mission by instrument flight.Subjects wore eye tracker to record eye movement data.Their performances of completing tasks were recorded and evaluated.Each group selected 9 subjects,according to the integrity and accuracy of sampled data,for the independent sample t-test comparison on task completion and additional task completion between groups by means of SPSS 16.0 software.Results The experienced group showed significant higher task performance and additional task scores than those of novice group (t=2.387-4.731,P＜0.05 or 0.01).Such eye movement indicators as frequency,average fixation duration,saccade frequency,saccade velocity and average saccade amplitude showed statistical differences between groups (t=2.212-5.601,P＜0.05 or 0.01).Distribution of attention in the relative fixation time (expressed by percentage) on altimeter and speedometer also showed statistical differences (t =2.007-2.731,P＜ 0.05).Conclusions The experienced group pilots have higher eye movement efficiency and better flying performance than novice group pilots.
