优化压路机的显示界面设计是本研究的重点，其中考虑了操作者认知负荷的影响，这对准确获取界面信息和提高认知效率有很大的帮助。为了降低操作者的认知需求，本研究修改了一个常用的通用显示界面。三种方法被用来测量认知负荷，包括主观（NASA任务负荷指数）和生理（眼动）测量和通过任务性能。这三种测量方法用于两组受试者：在四个给定任务中查看原始版本的受试者和查看修改后版本的受试者。研究结果表明，修改后的界面对四个任务的眼动和完成时间有显著影响。通过对三种测量结果的综合分析，发现改进后的界面比原界面对认知的要求更低，认知绩效更高，从而证明改进后的界面能有效降低认知负荷。本研究为工程装备显示界面设计的改进和评价提供了科学依据。
Optimizing a display interface design for rollers is the focus of this study, in which the effects of cognitive load of the operator are taken into consideration, which greatly contribute to acquiring interface information accurately and enhancing cognitive efficiency. To reduce the cognitive demand of the operator, a commonly used generic display interface is modified in this study. Three methods are used to measure the cognitive load, including subjective (NASA Task Load Index) and physiological (eye movement) measurements and through task performance. These three measurements are used with two groups of subjects: those who view the original and those who are given the modified version during four given tasks. The findings show that the modified interface has a significant impact on eye movement and completion time of the four tasks. After a comprehensive analysis of the results from the three types of measurement, it is found that the modified interface is less cognitively demanding than the original interface and allows a higher cognitive performance, which accordingly demonstrates that the modifications made are effective in reducing cognitive load. This study therefore provides the scientific basis for advancing interface designs and evaluating the display interface designs for engineering equipment.
