手机社交娱乐操作对驾驶人视觉参数影响研究

Influence of Mobile Phone Social Entertainment Operation on Driver's Visual Parameters

为探究手机社交娱乐操作对驾驶人视觉参数的影响,基于模拟驾驶器和SmartEye眼动仪设计模拟驾驶实验,采集驾驶人正常驾驶、拨打电话、收发信息等5种操作下视觉特征数据,应用拉依达准则和联合频数分布直方图进行数据归约.针对不同操作下视觉参数,应用箱形图和Kruskal-Wallis显著性检验,验证视觉参数评价指标的有效性.结果表明:随手机操作类型的不同,驾驶人水平和垂直视角标准差、视线离开道路时间百分比、扫视平均速度和眨眼持续时间呈显著性变化,可作为视觉参数影响的评价指标;观看视频和刷朋友圈操作对驾驶人视觉影响程度明显高于拨打电话和收发短信操作.

In order to explore the influence of mobile phone social entertainment operations on the driver's visual parameters,a simulated driving experiment was designed based on the simulated driver and Smart Eye tracker to collect visual characteristic data under 5 operating conditions.Then use the Pauta criterion and joint frequency distribution histogram for data reduction.Finally,based on the visual parameter box plots and Kruskal-Wallis significance test result under different operations,determine whether the visual parameters can be used as evaluation indicators.The results show that with the different types of mobile phone operation,the standard deviation of the horizontal and vertical viewing angles,the percentage of time off the road,the average speed of the glance,and the duration of the blink can show significant changes,which can be used as evaluation indicators of the influence of visual parameters.And watching videos and browse on Moments are significantly more distracting to the driver than making calls and sending and receiving text messages.
