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.

基于操作者认知负荷的压路机显示界面设计
优化滚轮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，极大地有助于准确获取界面信息，提高认知效率。为了减少操作员的认知需求，本研究修改了常用的通用显示界面。三种方法用于测量认知负荷，包括主观（NASA 任务负荷指数）和生理（眼动）测量以及通过任务表现。这三个测量值用于两组受试者：在四项给定任务中查看原始版本的受试者和获得修改版本的受试者。研究结果表明，修改后的界面对四项任务的眼球运动和完成时间有显着影响。通过对三种测量结果的综合分析，发现修改后的界面比原始界面的认知要求更低，认知性能更高，从而表明所做的修改对减少认知负荷是有效的。因此，本研究为推进界面设计和评估工程设备的显示界面设计提供了科学依据。
