A Study On The Usability Of Internet Shopping Mobile Terminal Interface For Middle-aged And Elderly People Combined With Cognitive Characteristics

With the continuous progress of Internet technology and the development of e-commerce,more and more middle-aged and elderly users participate in the trend of online shopping.According to the China Internet consumption trends report,the over-50 s are becoming the main consumers of some online products.With the aging of the society,middle-aged and elderly users have become an important consumer group in online shopping services.At present,there are deficiencies in the research on the shopping interface of the middle-aged and the elderly.On the one hand,the research on the usability of the interface of the mobile terminal is less than that on the web.On the other hand,there are relatively few researches on shopping interface for elderly users.In this study,the design elements and levels of the existing shopping interface are analyzed and extracted based on the features of the mobile shopping interface of middle-aged and elderly users.Through the combination of subjective and objective research methods to find the user preferences and influence the usability of mobile shopping interface design elements and its level;To build a model of the relationship among user cognitive characteristics,interface usability and interface design elements;This paper summarizes the research methods of mobile terminal design of shopping interface based on the cognitive characteristics of users,and provides support and help for the research and design of shopping interface for middle-aged and elderly users.The main research work includes the following aspects:(1)Research status and analysis: summarize the domestic and foreign research status on shopping interface,interface usability,middle-aged and elderly users and cognitive characteristics,analyze the main research methods and research results,and find the entry point of the research;(2)construct user cognitive feature scale: analyze the existing mobile terminal shopping interface,preliminarily extract the main page design elements in combination with the user survey,select the cognitive features related to the shopping interface,and establish the correlation between design elements and cognitive features;Through experiments and reliability and validity analysis,the cognitive characteristics evaluation scale of the user's online shopping interface was constructed.(3)interface usability experiment: analyze the basic process of using the shopping interface,extract the important design elements and their levels in the interface according to the contents included in the five levels of the interface,obtain the shopping interface prototype with different features by orthogonal method,and use Axure software to build the prototype;The interface usability experiment was carried out by combining the traditional usability test and eye movement experiment,and the experimental conclusions under different experimental environments and methods were analyzed and summarized.(4)Model building and analysis: combining the theory of quantification ? classes and multi-factor analysis of variance,the method of constructing design elements,interface usability,the relationship between the cognitive characteristics of model,analysis summary for the user to have important influence on the design of the element and its level;The usability design method of shopping interface for middle-aged and elderly users is summarized.(5)design practice and test: test the experimental conclusion and verify the validity of the experimental conclusion through the usability test of design practice and the comparative analysis of data.
