The Research Of Evaluation And Quantification Model Of Instant Messaging Application Based On User Experience

Under the background of development of computer and internet technology,instant messaging application develop into a important communicating platform following e-mail.With the growing number of instant messaging applications,on the one hand competition among providers is more fierce,on the other hand users need to choose their own applications.Nowadays,meeting the two demands is a hot research.After investigation I find that the main research about instant messaging application focuses on three areas.The first is about classification,characteristics,advantages and disadvantages,features and technology of instant messaging application.The second aspect is about users' choice,satisfaction and other issues combination of users' characteristics in different work,study,entertainment.However,based on the user experience to mine satisfaction and acceptance is a major research gap.The third aspect are the factors of instant messaging application.Many scholars' research results show usefulness,ease of use,security,privacy are major factors which affect the users' wishes of downloading.However,comprehensive evaluation of research about instant messaging system is relatively scarce.To solve these problems above,I look evaluating factors of instant messaging application as the main line and analysis in depth the relevance of user experience and instant messaging application evaluation.I generate questionnaires from the interview results and analysis it with SPSS software.First I make the instant messaging application factors dimensionality reduction come true through principal component analysis.Then I establish index evaluation system with the using of factor analysis.Finally the evaluation model of instant messaging application is built up through AHP.The evaluation model includes cognitive experience,aesthetic experience,behavioral experience and emotional experience.The part of empirical research selects the higher frequency used applications to analyze.I select Wechat,QQ,Renren,Michat and Alitalk to evaluate and optimize the designing of the Michat combined with the evaluation results.Test results show that the user experience level is improved to justify the validity of the evaluation model.It provides references for the research of evaluation of instant messaging applications.
