摘要
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。
To study the visual features of air traffic controllers,an integrated experimental platform based on a radar control simulator and a Tobii T60 eye tracker was built. The fixation areas were decided through coordinate transformation. There were 6 flights in the control area when number was steady. According to existence of flight conflict,the stage that was chosen to be analyzed was divided two parts,and Markov chain method was used to analyze the state transition probability of visual fixation data in various visual areas. The study indicates that same subject adopts different methods to acquire the information on screen under different situations,that sometimes,the subject pays many fixation points to one area and will not move his fixation to other areas until he acquires enough information,but sometimes,the subject moves his attention easily and saccades more,and that different subjects adopt different methods under same situation.
