双任务下仪表对新驾驶员视觉前注意影响研究

Research on Effects of the Dashboard on the Novice Drivers' Visual Pre-attentive Process under Dual-task

研究在双任务环境下,仪表盘指针的长度和宽度以及字符颜色等因素对于人员认知过程影响。本研究采用实验方法,对被试人员操作过程中反应时和正确率进行数据分析。结果显示,指针宽度和字符颜色对于被试反应时间具有显著影响;指针长度对于被试操作正确率具有显著影响。研究结果可给驾驶过程认知模型建立提供数据支持,可以帮助仪表设计人员更好的进行仪表界面设计和测评工作。

This paper researched the effects of the dashboard-pointers＇ length and width and characters＇color in the drivers＇ cognitive process in double mission context. In this research, we adopted experimental method,and made data analysis of the reaction time and the accuracy in personnel operating process. The results showed that the width of pointers and the color of characters had significant influence on the reaction time~ the length of pointers had significant influence on operating accuracy. The results of this paper could provide data support to create driving process cognition model, also could help instrument designers do instrument interface design and assessment work better.
