基于车载语音交互方式下的驾驶员注视特性分析

Analysis of Driver’s Gaze Characteristics Based on Vehicle Voice Interaction

为了明确车载语音交互方式下驾驶员的注视特性,采用Tobii Glasses眼动仪采集了真实城市道路环境下多位驾驶员的眼动数据,通过注视热点图算法,构建注视热点叠加图,对比分析了不同交互方式下驾驶员的注视分布规律。研究表明:车载语音交互方式下,驾驶员注视分布主要集中于前方道路区域,其注视比例均在88%以上;驾驶员对前方道路区域的注视比例都高于手机操作方式下的注视区域,驾驶员对手机区域的注视比例都小于手机操作方式下的注视区域。研究结果既能帮助驾驶员直观地了解行车时操作手机的危害,也能为驾驶员明确车载语音交互方式提供驾驶安全性的理论支撑。

In order to clarify drivers’fixation characteristics under the on-board voice interaction mode,Tobii Glasses eye tracker was used to collect the eye movement data of multiple drivers under the real urban road environment,and the fixation hot spot overlay map was constructed through the fixation hot spot graph algorithm,and the fixation distribution rules of drivers under different interaction modes were compared and analyzed.The research shows that:under the on-board voice interaction mode,drivers’gaze distribution is mainly concentrated in the front road area,and the staring proportion is above 88%.The proportion of drivers’gaze at the front road area is higher than that of the mobile phone operation mode,and the proportion of drivers’gaze at the mobile phone area is lower than that of the mobile phone operation mode.The research results can not only help drivers intuitively understand the harm of operating mobile phones while driving,but also provide theoretical support for driving safety for drivers to clearly understand the way of on-board voice interaction.
