User experience design of VR-AR hybrid mobile browsing system based on mental model

At present, the augmented reality technology based on mobile platform has already been used in a wide range of applications in the field of human-computer interaction. However, there is a problem that the neglect of important role of cognitive psychology and the luck of presentation of interactive information cause a poor user experience of the application. In this paper, a mobile virtual reality and augmented reality browsing system is proposed. A human-computer interaction experiment was performed by the combined use of the Macro Mental Model and Micro Mental Model. The user interface of this system was designed and realized through repeated evaluation and usability testing based on the implantation of user-centered design principles. Finally, interactive experience of this system approaches the user's psychological expectations. Furthermore, through the switch freely between virtual reality and augmented reality environments, users can obtain two distinct interactive experiences. The experimental results show that the user interface design of this system can not only mobilize the enthusiasm of user interaction, but also improve the sense of the man-machine interactive experience on the aspect of usability and efficiency.
