摘要
为了研究管制员的视觉搜索特征,利用雷达管制模拟机模拟真实的管制场景,并用Tobii X2-60眼动仪记录实验中被试的眼动数据。在对管制员视觉行为及其表征参数分析之后,选取注视持续时间、水平及垂直方向视角、扫视幅度和扫视速度等眼动指标来表征管制员的视觉搜索特征;通过设置模拟管制场景中飞机的数目,即5、7、10架,从而比较在不同飞机数目情况下的管制员的视觉搜索特征。结果表明:在对眼动指标进行分段统计时,被试的眼动数据在不同范围上存在着明显的分布差异;再对上述数据进行方差分析后,发现被试的视觉搜索特征随飞机的数目变化没有发生显著差异。
In order to study visual search features of traffic controllers, a radar control simulator was used to simulate real air trat fic control scenes. A Tobii X2-60 eye tracker was also applied to record eye movement data of every subject. After analyzing the visual behavior of traffic controllers and its parameters, eye movement indicators like the fixation duration, horizontal and vertical view angle, saccadic range and saecadic speed were selected to characterize subjects＇ visual search features. By setting various numbers of aircrafts, the visual features under different situations were compared. With partition statics, subjects＇ eye movement data shows an obvious difference of distribution. In addition, it appears that subjects＇ visual search features have no evident difference with the change of aircrafts＇ number after using analysis of variance to compare the data.
