Research On The Quantization Of User Experience Of Application For Collaboration Based On Cognitive Load Theory

With the rapid development of the Internet in the country,people began to emphasize the importance of teamwork and information sharing in their daily work and study,accompanied by a growing number of domestic enterprises and individual users began to use the team collaboration applications to improve the efficiency of daily work and learning.Therefore,the application of team collaboration as the current most dynamic and development prospects of the field,is rapidly rising and development.On the other side,users will have a cognitive burden in the process of using the team collaboration application,and then affect the user's subjective experience,which has become the focus of design research.However,the user experience reflects the subjective perception of the user experience,the studies of current domestic user experience focused on qualitative research.There is relatively inadequate research on how to quantify the user experience and how the results are used,especially in the areas of team collaboration.Therefore,the research on user experience quantification for team collaboration applications has a high research value,but also has some challenges.This paper is based on the related theory of cognitive load and quantitative user experience,taking cognitive load caused by user in the use of team collaboration class application as the breakthrough point,then discussing their effects on the user experience,and obtaining impact factors of user experience of team collaboration class application through qualitative and quantitative analysis,using the method of factor analysis to select final primary and secondary factors,and building the hierarchy structure model of user experience impact factors of team collaboration class application.Then with the help of analytic hierarchy process,the weight of primary and secondary factors will be determined,and finally the evaluation system of user experience of team collaboration class application can be established.Finally,the paper discusses the application domain of the team collaboration application's user experience evaluation system,which is mainly reflected in two aspects: one is to provide reference for the evaluation and optimization of team collaboration application;the other is to evaluate the impact factors in the system to provide suggestions for the design and development of team collaboration application.Finally,based on the concrete case,the case study is evaluated quantitatively by using the user experience evaluation model of team collaboration,and the design optimization is carried out according to the result of the evaluation.It provides reference value of the research idea and method for the quantitative evaluation and design optimization of the team collaboration application's user experience.
