中文摘要:

      目的 在智能养老广泛应用的背景下，探索服务机器人设计色彩对老年人视觉认知绩效的影响。方法 选取24名老年被试者进行眼动实验，获取被试者观察8组实验图片时的眼动指标。首先，对总注视次数和第一次注视时间这两项眼动数据进行客观分析，采用单因素方差分析方法来验证数据的显著性;其次，对老年被试者与青年被试者数据进行t检验分析，研究不同年龄段用户对服务机器人色彩设计的视觉认知绩效是否存在差异;最后，利用相关性分析方法验证色弱是否会影响老年人的视觉认知绩效。结论 老年人对黑色比较敏感，对白色极容易忽略，冷暖色之间不存在显著差异;不同年龄段用户对颜色关注度存在差异;色弱会略微影响老年人的视觉认知绩效，但不会影响老年人对色彩的选择。

英文摘要:

      Under the background of the wide application of intelligent pension, this paper explores the influence of service robot design color on the visual cognitive performance of the elderly. 24 elderly subjects are selected for eye movement experiment, and the eye movement indexes are obtained when the subjects observed 8 groups of experiment pictures. Firstly, the data of AOI fixation count and AOI time to first fixation are analyzed objectively, The significance of the data is verified by using one-way ANOVA. Secondly, t-test was used to analyze the data of elderly and young subjects to study whether there are any differences in the visual cognitive performance of color design of service robot among users of different age groups; Finally, correlation analysis was used to verify whether chromatic weakness affects visual cognitive performance of the elderly.. The elderly are more sensitive to black, easily to ignore white, and there is no significant difference between warm and cold colors. Users of different ages have different attention to color. color weakness slightly affects the visual cognitive performance of the elderly, but does not affect the color choice of the elderly.
