目的 探讨经验飞行员和新手飞行员在模拟定向飞行任务中眼动规律的差异. 方法 飞行时间≥1000 h(经验组)与≤300 h(新手组)两组共30名飞行员分别完成空间定向仪中坚信仪表飞行课目,并在此过程中佩戴眼动仪,同步收集各个眼动指标并记录各任务成绩.依据数据完整性和录制眼动视频的准确性,每组选取9名飞行员的数据进行分析.采用SPSS 16.0软件对两组飞行员的任务成绩、附加任务成绩进行独立样本t检验. 结果 飞行时间≥1000 h组任务成绩和附加任务成绩均优于≤300 h组,其差异具有统计学意义(t=2.387～4.731,P＜0.05或0.01)；注视频率、平均注视时间、眼跳频率、眼跳速度及平均眼跳幅度5个眼动指标,两组间差异均有统计学意义(t=2.212～5.601,P＜0.05或0.01)；在注意力分配上,两组间高度表、速度表注视时间百分比差异具有统计学意义(t=2.007～2.731,P＜0.05). 结论 经验组飞行员比新手组拥有更高效率的眼动模式和更好的飞行绩效.
目的 探討經驗飛行員和新手飛行員在模擬定嚮飛行任務中眼動規律的差異. 方法 飛行時間≥1000 h(經驗組)與≤300 h(新手組)兩組共30名飛行員分彆完成空間定嚮儀中堅信儀錶飛行課目,併在此過程中珮戴眼動儀,同步收集各箇眼動指標併記錄各任務成績.依據數據完整性和錄製眼動視頻的準確性,每組選取9名飛行員的數據進行分析.採用SPSS 16.0軟件對兩組飛行員的任務成績、附加任務成績進行獨立樣本t檢驗. 結果 飛行時間≥1000 h組任務成績和附加任務成績均優于≤300 h組,其差異具有統計學意義(t=2.387～4.731,P＜0.05或0.01)；註視頻率、平均註視時間、眼跳頻率、眼跳速度及平均眼跳幅度5箇眼動指標,兩組間差異均有統計學意義(t=2.212～5.601,P＜0.05或0.01)；在註意力分配上,兩組間高度錶、速度錶註視時間百分比差異具有統計學意義(t=2.007～2.731,P＜0.05). 結論 經驗組飛行員比新手組擁有更高效率的眼動模式和更好的飛行績效.

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.
