Research On The Elderly-oriented Design Of Shopping Website Based On Visual Cognitive Theory

In the background of an increasingly aging society,the popularity of “Internet Plus” is gradually changing the way of daily life for the elderly.In particular,online shopping is widely accepted by the elderly.More and more elderly people are becoming online shopping consumers.The potential force.This article through the previous analysis of the status quo of the domestic and foreign elderly website and shopping site found that the quality of the domestic elderly shopping site is uneven,but also lacks a reasonable guideline for appropriate aging design,so it is clear that this article for the shopping site aging design research value and direction.In the research process,based on the theory of visual cognition,this paper deeply studies the selective attention features and cognitive mechanisms of visual cognition,and analyzes and summarizes the aging cognitive features of visual cognition,including visual physiological characteristics and visual Cognitive features and environmental influences.On the basis of the research,the key visual elements in the appropriate aging design were summarized through questionnaires for the elderly and visual experience points and experience measurements in the existing shopping sites on the mobile site.In the experiment,the selection of clustering samples for page layout,graphics and text matching and color elements was performed.The task performance test was performed on the comfortable reading font size,and the experimental results were evaluated by the method of cognitive load measurement.In the experiment process,Tobii eye tracker was used to record the eye movement data of the testers,and data indicators such as the visual time of the user interface and the fixation point were obtained,and the experimental results were objectively verified.Combining the experimental results with the user's research,we found that the shopping website should follow the visual principles of aging design.Finally,based on the combination of theory and practice,based on the visual principle of ageing design,the aging design of “Mobile Taobao Old Age Edition” is taken as an example,and the feasibility is verified through experimental tests,and the correctness of the design principles is proved.
