摘　　要：自适应界面中经常遇到调整界面项目区域位置和增大区域面积,吸引用户注意,提高交互效率的情况.本文对自适应界面项目区域位置变化和区域面积增大过程中人的认知特性进行了研究,为自适应界面设计提供依据.设计了工效学实验,使界面自适应项目在中间位置和其他位置进行随机切换,界面自适应项目在原面积界面和增大面积界面之间随机切换,模拟界面元素的自适应过程,要求被试完成视觉搜索任务,记录被试反应时间和正确率.研究表明,在区域位置随机切换条件下,变化方向(上下左右)、变化距离对反应时间均有显著影响;由反应时间随距中心位置距离变化曲线图,眼动热点图,发现被试者对上下方向的变化更敏感;在本文实验条件下,界面项目上下方向自适应变化距离不能超过该方向屏幕尺寸的15%,左右变化不能超过该方向屏幕尺寸的25%;当增大的面积大于原面积的125%时,动态切换因素对反应时间影响显著,所以增大的面积不能超过原面积100%.In order to attract users'attention and improve the efficiency of interaction,adjusting the position and increasing the area of interface elements is very common in adaptive interface.In this paper,we studied the cognitive characteristics of people in the process of the change of regional location and the increase of regional area of the adaptive interface,which provides guidelines for the design of the adaptive interface.Ergonomics experiments were designed to make the interface adaptive items randomly switch between the middle position and other locations,as well as the original area interface and the enlarged area interface.The subjects were asked to complete the visual search task,and the reaction time and accuracy of the subjects were recorded.The results show that the direction(up,down,left and right),and the distance have significant effects on the reaction time.The eye movement heatmap shows that subjects are more sensitive to change in the direction of the up and down.Under the experimental conditions,the adaptive change distance of the interface items in the up and down directions can not exceed 12.5%of the screen size;the change distance cannot exceed 25%of the screen size in the direction of left and right.When the increase is greater than 125%of the original area,the dynamic switching factor has a significant effect on the reaction time,so the proportion of area increase can not exceed 100%.
