【摘要】：为了研究应激情况下驾驶人的视觉特性,分析了不同应激场景下驾驶人的眼动数据。采取动态聚类方法划分注视区域,选取了合适的视觉特性指标作为分析指标。运用主成分分析法及统计分析方法研究了被试驾驶人眼动数据,得到了基于应激响应的驾驶人视觉特性。试验结果表明:驾驶人在应激场景下视觉分配较为集中,遇到应激场景时,驾驶人更习惯于从前方近处区域作为获取交通信息的主要区域,当场景中出现移动的目标物时,驾驶人会根据目标物的移动范围选取1~2个相关的辅助区域进行信息获取的补充。同时,驾驶人对主要区域以注视为主,辅助区域以扫视为主。
[Abstract]:In order to study the visual characteristics of drivers under stress, the eye movement data of drivers in different stress scenarios were analyzed. The suitable visual characteristic index was selected as the analysis index, and the principal component analysis and statistical analysis were used to study the eye movement data of the tested driver, the main component analysis method and the statistical analysis method were used to study the human eye movement data. The visual characteristics of the driver based on the stress response are obtained. The experimental results show that the visual distribution of the driver is more concentrated in the stress scenario, and when the driver encounters the stress scenario, The driver is more accustomed to using the near front area as the main area for obtaining traffic information, when moving objects appear in the scene, According to the moving range of the object, the driver will select 1 ~ 2 relevant auxiliary areas to supplement the information acquisition. At the same time, the driver will focus on the main area, and the auxiliary area will be the scanning area.
