| 目的 随着人们生活水平的提升，冰箱已然成为了每家每户必不可少的家用电器，冰箱操作界面的可用性也越来越受到用户的重视。经调查发现，用户对于市面上大多数冰箱操作界面的设计并不满意，因此通过设计照明及眼动实验对冰箱操作界面进行优化，以提升用户的视觉和操作体验。方法 选取3款冰箱操作界面作为研究对象，在环境照度为150 lx的家居环境下，设计照明实验，测量冰箱操作界面上小字符、中字符和大字符的亮度以及字符与背景的亮度对比度，结合被试主观评价确定最优亮度区间、最优亮度对比度区间。通过设计眼动实验，获取被试佩戴眼动仪完成指定任务的精确时间、瞳孔直径数据、轨迹图及热点图，分析3款冰箱操作界面设计上的优劣。结果 照明实验得出了小、中、大字符的最优亮度区间分别为50~65 cd/m2、45~85 cd/m2、40~120 cd/m2，最优亮度对比度区间分别为40~60、20~70、40~130。眼动实验得出了3款冰箱操作界面的设计优劣表。结论 对实验结果进行总结分析，提出冰箱操作界面优化设计方案，即小字符亮度57.5 cd/m2，亮度对比度50;中字符亮度65 cd/m2，亮度对比度45;大字符亮度80 cd/m2，亮度对比度85，并绘制设计图。 |

| Abstract: |
| With the improvement of people’s living standards, refrigerators have become an indispensable household appliance in every household, and the usability of the refrigerator operation interface has received more and more attention from users. After investigation, it is found that users are not satisfied with the design of most refrigerator operation interfaces on the market. Therefore, the refrigerator operation interface is optimized through design lighting and eye movement experiments to enhance the user’s visual and operating experience. Three types of refrigerator operation interfaces are selected as the research objects. The illumination experiment is designed under the environment illumination of 150 lx. The brightness of small characters, middle characters and large characters on the refrigerator operation interface and the brightness contrast between characters and background are measured. Combined with the subjective evaluation of the subjects, the optimal brightness range and the optimal brightness contrast range are determined. Through the design of eye movement experiment, obtain the accurate time, pupil diameter data, trajectory map and hot spot map of subjects wearing eye tracker to complete the specified task, analyze the advantages and disadvantages of three refrigerator operation interface design. The lighting experiment shows that the optimal brightness intervals for small, medium, and large characters are 50~65 cd/m2, 45~85 cd/m2, 40~120 cd/m2, and the optimal brightness and contrast intervals are 40~60, 20~70, 40~130, respectively. The eye movement experiment got a table of the design advantages and disadvantages of the operating interface of 3 refrigerators. The experimental results are summarized and analyzed, and the optimal design plan for the refrigerator operation interface is proposed, namely, the brightness of small characters is 57.5 cd/m2, the brightness contrast is 50; the brightness of medium characters is 65 cd/m2, the brightness contrast is 45; the brightness of large characters is 80 cd/m2, and the brightness is contrast 85, and draw design drawings. |
