A Study on Evaluation Model of VR Shopping Experience based on User-Centered Approach

VR shopping could become a new purchasing channel that combines the advantages of offline shopping and online shopping to provide a new immersive experience for users. According to the changes of shopping environment, this paper proposes the necessity of studying shopping experience in VR, aiming to give comprehensive evaluation indexes for VR shopping experience.Firstly, we reviewed the research related on online and offline shopping experiences, VR shopping, and the characteristics of virtual reality. Also, through some case studies, we have an understanding of the current development progress of VR shopping platform. In VR shopping environment, a comprehensive understanding of shopping experience is needed. Therefore, we adopt the user-centered design method combined with context mapping and correspondence analysis to integrate online and offline shopping experiences, also analyze the relationship between user experience and interaction in the shopping process. On the basis of integrated shopping experience, we finally proposed an evaluation model of VR shopping experience combines 1) Integrated Shopping Experience, 2) Usability of VR Environment and System, 3) Features of VR, and then revised and supplemented through expert evaluation, result to a total of 33 evaluation items. It is expected that it can be used to construct and evaluate the new VR shopping environment and provide reference for the development of VR shopping.
