Usability Evaluation of the Ordering Interface Based on Cognitive Differences
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 efficiency and generate higher economic value.This article first 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,find 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 efficiency 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.
