注意偏侧化对驾驶视觉搜索的眼动表现证据

Eye-movement evidence of pseudoneglect on driving visual search bias

为探究驾驶过程中伪忽视注意在不同道路等级条件下视觉搜索偏好的差异,通过实车驾驶的试验方法,记录15名驾驶人分别在3种真实道路环境(高速公路、快速公路、二级公路)驾驶过程的眼动数据(兴趣区、注视时长、注视点、瞳孔大小),以便发现驾驶人空间注意的视觉眼动搜索模式。结果表明:驾驶人首先表现出轻微偏左的不对称空间注意的特点,随着道路条件的复杂程度提高(从高速公路、快速公路到二级公路),驾驶人认知负荷提高,驾驶空间注意的眼动搜索呈现出趋中到趋右的安全搜索模式倾向。

In order to explore the difference in visual search preference of pseudoneglect during driving under different road grades,the experimental method of real car driving was adopted.The eye movement data(interest area,fixation duration,fixation point and pupil size)of 15 drivers driving in three real road environments(expressway,expressway,and secondary highway)were recorded to find the visual eye movement search pattern of drivers′spatial attention.The results show that the drivers first showed a slightly left-biased asymmetric spatial attention.With the increase in the complexity of road conditions(from the expressway,expressway to secondary highway),the cognitive load of drivers increased.The eye movement search of drivers′spatial attention showed a tendency from middle to right safety search mode.
