中文摘要:

      目的 重点探索不同光照强度对装载机仪表盘界面信息读取的影响，确定驾驶员读取信息的最佳光照环境。对仪表盘界面布局中六大主要仪表区域进行兴趣区划分和编码，总结被试的视觉行为规律。方法 采用眼动实验与主观评价量表相结合的方法，以三款具有代表性的装载机仪表盘人机界面为研究对象。结果 7000~20000 Lux的光照环境下被试搜索与认读时间最短，反应正确率最高;1000~3000 Lux的光照环境下视觉舒适度最高。综合评价的结果表明1000~3000 Lux视觉工效最佳。结论 不同的光照度对装载机驾驶员视觉作业的结果存在显著的差异性。转速表和显示屏对于装载机仪表盘而言是最受关注的仪表区域。仪表盘B在三款仪表布局中仪表认读时间最短，反应正确率最高且最受用户欢迎，这为以后的装载机仪表盘设计研究提供了参考。

英文摘要:

      The work aims to explore the influences of different light intensity on the information reading of the wheel loader dashboard interface, determine the best light environment for the driver to read information, divide and code the six major instrument areas in the interface layout of the instrument panel, and summarize the visual behavior rules of the subjects. The eye movement experiment and the subjective evaluations scale were combined to study the representative human-machine interfaces of wheel loader dashboard. In the light environment of 7000-20000 lux, the time of searching and reading of subject was the shortest, and the correct rate of reaction was the highest; the visual comfort was the highest in the light environment of 1000-3000 lux. The results of comprehensive evaluation showed that the visual ergonomics under 1000-3000 lux was the best. Different illumination has significant different effects on the results of loader driver’s visual operation. The tachometer and display screen are the most concerned instrument area for the loader instrument panel. Instrument panel B has the shortest reading time and the highest response accuracy among the three instrument layouts, which provides reference for the future design and research of loader dashboard.
