摘要: 情境意识(SA)是影响管制员决策和操作绩效的重要因素。为探究有效测量管制员SA水平的客观指标,搭建模拟塔台管制员眼动试验平台,设计并完成3组不同任务难度的试验。利用最近邻算法(NNI)量化识别被试眼动注视特征,并分析不同注视特征管制员的SA和操作绩效。研究结果表明:随着任务难度的增加,被试的SA水平均呈下降趋势;注视模式呈离散型分布的被试有更高的SA水平和操作绩效;眼动分析中的NNI注视指数是未来实时人因工程中测量SA水平的潜力指标。

Abstract: SA is an important factor influencing the decision-making and operational performance of ATC. In order to explore the objective and effective indicators of the SA of the controllers, an eye-tracking experiment platform to simulate the tower control was built. Three group experiments of varying task difficulty based on the difference of flight number were designed and carried out. NNI algorithm was utilized to quantify subjects' eye-tracking fixation mode. The differences in SA and operational performance between controllers of different NNI fixation features were analyzed comparatively. Results reveal that there is a negative correlation between the SA of the subjects and task difficulty, that the subjects, whose NNI fixation indexes have a discrete distribution, have higher levels of SA and better operational performance, and that the NNI fixation index in the eye movement analysis is a potential indicator of SA in future real-time human factors engineering.

Key words: air traffic controller (ATC), situation awareness (SA), nearest neighbor index (NNI), fixation mode, performance analysis
