研究旨在对着陆过程中的注视行为特征进行实验研究。基于模拟飞行环境,应用眼动仪实时记录并分析目视着陆中的注视百分比、注视转移次数、注视时间等特征。结果表明:目视着陆绩效优组对舱外景区的注视百分比显著高于绩效差组、总的注视转移次数显著多于绩效差组、对舱内仪表的平均注视时间显著短于绩效差组,注视模式与着陆绩效之间存在较强相关性。研究结论认为目视着陆中应建立更多外景注视参考点,同时提高舱内仪表信息搜索效率。
The purpose of the study is to study the characteristics of gaze behavior during landing. Based on the simulated flight environment, the eye tracking system records and analyzes the fixation percentage, fixation frequency and fixation time of the visual landing in real time. The results showed that the visual fixation performance of the excellent visual landing group was significantly higher than that of the poor performance group, the total number of fixation shifts was significantly more than that of the poor performance group, and the mean fixation time of the in-flight instrument was significantly shorter than that of the poor performance group. There is a strong correlation between fixation patterns and landing performance. The conclusion of the study is that more landscaped reference points should be established in the visual landing and the search efficiency of the in-flight instrumentation should be improved.
