基于视觉行为的智能车载交互界面色彩编码研究

对智能车载交互界面信息进行色彩编码，提高视觉信息的辨识度，从而降低驾驶员在驾驶过程中的认知负荷，提高驾驶员在行驶过程中的认知绩效及驾驶安全性。对驾驶员在驾驶过程中视觉认知过程进行分析，构建视觉注意模型。然后通过问卷形式来获取视觉信息功能元素的操作复杂度、驾驶相关度和使用频率之间的关系，结合调研结果得到使用权重较高的功能元素。对使用权重高的功能元素进行图标设计，通过用户反馈得出最优的图标色彩编码。依据图标方案用户调研数据，在某汽车企业的三种企业形象色中，蓝色是相对于其他两种颜色易于捕获的色彩。蓝色易于驾驶员在行驶过程中进行注意捕获，从而提高驾驶员的认知绩效，将蓝色应用于智能车载信息交互界面呈现的设计中。

Color Coding of Intelligent Vehicle Interactive Interface Based on Visual Behavior

The work aims to conduct color-code on the information of the intelligent vehicle interactive interface to improve the recognition of visual information, thereby reducing the driver??s cognitive load during driving, improving the driver??s cognitive performance and safety during driving. The driver??s visual cognition process during the driving is analyzed to build a visual attention model; then the questionnaire is used to obtain the relationship between the operational complexity of the visual information functional elements, the driving relevance and the frequency of use. Combined with the survey results, function elements with high weight are obtained. The icon design is performed on the function elements with high weight, and the optimal icon color coding is obtained through user feedback. Based on user survey data of the icon scheme, in the three colors of company image, blue is a color that is easier to capture than the other two colors. Blue is easy to capture the attention of the driver during driving, which improves the driver??s cognitive performance. Blue is used in design of intelligent vehicle information interaction interface presentation.
