为研究管制员对界面中信息的注意特征,整合雷达管制模拟机和眼动仪,构建试验平台,并通过坐标转换,将被试注视点在眼动仪系统中的屏幕坐标与航空器所在坐标系中的地理坐标进行匹配,确定被试关注的位置。将界面有6架航空器的试验阶段分为无冲突和存在飞行冲突2种情况,应用马尔科夫链模型分析被试的视觉注视转移特征。结果发现,同一被试在不同情境下采取不同的策略获取界面中的信息,有时倾向于对各位置采取多次长时间注视后转移的策略,有时倾向于对各区域均采取单次注视,频繁扫视的策略。相同情境下不同被试获取界面中信息的方式也不相同。
In order to study the controller’s attention characteristics of the information in the interface, the radar control simulator and the eye tracker are integrated, and a test platform is constructed. Through the coordinate transformation, the screen coordinate of the test eye gaze point in the eye tracker system and the coordinate system of the aircraft In the geographical coordinates match to determine the location of the subjects concerned. The experimental stage with six aircraft interfaces is divided into two cases: collision-free and flight-collision. Markov chain model is used to analyze the visual fixation transfer characteristics. The results showed that the same subject in different situations to take different strategies to obtain information in the interface, and sometimes tend to take a long time for each location after the strategy of watching and shifting, and sometimes tend to take a single look at each region, frequent Glance strategy. In the same situation, different subjects get the information in the interface in different ways.
