高速公路广告牌背景色彩对驾驶员注视特性的影响分析

Analysis to Influence by Background Color of Ads Plates on Highway to Fixation Characteristics of Drivers

从驾驶员动态视觉角度出发,利用眼动仪设备对6名驾驶员进行眼动试验,基于试验数据分析高速公路广告牌背景色彩对驾驶员平均注视次数及平均注视时间的影响情况,并利用回归函数对试验数据进行拟合。研究结果表明:高速公路广告牌背景色彩越鲜艳,与周围环境对比性越强,其越能引起驾驶员的关注,驾驶员辨识它所需的时间也就越短,反之则越长;高速公路广告牌背景色彩与驾驶员平均注视次数及平均注视时间之间存在一定的定量变化关系。

From the dynamic visual angle of drivers, this paper introduces using eye tracker device to give eye tracking experiments to 6 drivers, with the test results, the test data is used to analyze the influence by background color of ads plates on highway to average fixation times and average fixation time of drivers, and use regression function to fit the test data. Results show that the brighter background color of Ads plates is on highways, the greater contrast is with ambient environment, which can better draw attention of drivers, who need less time to identify it. The background color of Ads plates on highway has certain quantitative relationship with average fixation times and average fixation time of drivers.
