低光照度下人机界面背景色眼动分析评价研究

为研究在低光照度情景下不同明度背景色人机界面的视觉工效，从而为此情景下的人机界面设计提供一定的参考，针对1.0~3.5 lux光照条件下的低光照度情景，对两个不同明度背景色的汽车中控人机界面设计方案进行视觉目标捕捉的眼动测试与主观感受评测，筛选出视觉工效较好的设计方案。在此过程中，对设计方案进行眼动测试，并收集用户主观评分，最后通过评价指标数据与权重进行计算，并依据两个设计方案的加权得分对其进行比较。结果表明，在1.0~3.5 lux的光照条件下，低明度背景色人机界面的视觉工效优于高明度背景色人机界面。

Eye Movement Analysis and Evaluation of Human-Computer Interface Background Color Under Intermediate Vision

In order to research the visual ergonomics of the human-computer interface with different background colors in low illumination conditions,and provide some reference for the design of human-computer interface in this condition,aiming at the low illumination condition under 1.0-3.5 lux illumination,eye movement test and subjective perception evaluation are carried out for two different illumination background color design schemes of vehicle central control humancomputer interface,and a better visual ergonomics design scheme is screened out.In this process,eye movement test is carried out on the design scheme,and subjective user scores are collected.Finally,the evaluation index data and weights are calculated,and the weighted scores of the two design schemes are compared.The results show that under the illumination of 1.0-3.5 lux,the visual ergonomics of the human-computer interface with low light background color is better than that of the human-computer interface with high light background color.
