候车视觉搜索与公交车体外观特征的眼动跳视研究

Eye Saccade Research for WaitingVisual Search and the Characteristic of Bus BodyAppearance

通过模拟乘客等候公交车时的真实场景,运用眼球运动追踪设备对城市公交车车体外观的设计布局进行眼动实验与研究.收集被试者观察公交车进站时的视觉参数数据,对数据进行归纳整理,比较被试者在辨认出目标公交车前后眼动跳视数据上的差异,分析数据差异存在的原因,从而得出候车者视觉搜索特征与公交车车体外观关系的相关结论.并对现有公交车车体外观进行优化改良设计,减少不必要的视觉干扰,提升候车乘客在候车过程中的视觉搜索体验,从而引导乘客无障碍地搭乘上目标公交车辆.

Through simulating the scene when passengers are waiting for the bus,an eye tracking equipment was used to estimate the layout of bus body appearance.An experiment was designed to compare the difference between the saccade data before and after subjects＇ visual cognition.By analyzing the reason of data difference,the relationship between the visual search features and appearance of bus body was achieved.The conclusion can be used to optimize the appearance design of bus body and reduce unnecessary visual interferences,which can enhance the waiting passengers＇ visual search experience and let them get on the bus without hindrance.
