基于认知差异的点餐界面可用性评价

Usability Evaluation of the Ordering Interface Based on Cognitive Differences

近年来,线上点餐的中年用户数量激增,但其界面设计的普适性相对欠缺,存在较大的优化空间。运用设计学科方法对中年用户点餐体验进行优化,能提高点餐效率,产生更高的经济价值。本文先通过感性问卷调研,得出中、青年用户对点餐界面的感性认知差异评价。再利用眼动实验得出点餐界面可用性评价。最后,综合分析总结两项评价结果,找出点餐界面中待解决问题,并根据这些问题提出普适设计建议:其一,加大导航栏字号、采用通俗词语、利用色彩加强视觉引导来帮助中年用户理解界面信息;其二,将界面中的装饰性图片替换为功能性图片,可以有效提高中年用户点餐效率;其三,增加切换控件部分在界面的占比,加入自动播放功能,引导中年用户使用该功能。

In recent years,the number of middle-aged users of online ordering has increased sharply,but the universality of its interface design is relatively lacking,and there is a large room for optimization.Applying design methods to optimize the ordering experience of middle-aged users can improve ordering effi ciency and generate higher economic value.This article fi rst conducts a perceptual questionnaire survey to obtain the perceptual cognition difference evaluation of middle-aged and young users on the ordering interface.Then,using eye movement experiments to obtain the usability evaluation of the ordering interface.Finally,comprehensively analyze and summarize the results of the two evaluations,fi nd out the problems to be solved in the ordering interface,and propose universal design suggestions based on these problems:First,Increase the font size of the navigation bar,use popular words,and use color to enhance visual guidance to help middle-aged users understand interface information.Second,Replacing decorative images in the interface with functional images can effectively improve the ordering effi ciency of middle-aged users.Third,Increase the proportion of switching controls in the interface,add automatic playback function,and guide middle-aged users to use this function.
