Abstract: With the rapid development of virtual reality(VR) technology in recent years,the VR industry is currently growing fast.Although VR provides many new possibilities for content form,due to the immaturity of VR application design,designers in the VR industry still face severe challenges.Design of VR applications still needs to be verified by users.Therefore,user expe-rience(UX) analysis is really critical to the success of VR software development.At the same time,with the increase of users' requirements for VR content quality,whether the content is attractive enough will greatly affects users' experience and determine the service life of VR applications.Consequently,searching for interaction events that will affect VR UX is critical to improve user stickiness.At present,the researches on VR mainly focus on the improvement of hardware and software,and pay less attention to the content event design.Moreover,there is no unified and clear standard for VR UX evaluation.This paper attempts to find out the relationship between user traits,VR interaction events and user experience through realistic experiments.This paper firstly defines four types of VR interaction events,and designs a questionnaire for collecting the tester's traits and their subjective evaluation.During the experiment,objective physiological data of the testers and their participation process are recorded.The 80 testers are divided into two groups to experience two types of VR games with constant time.The statistical method and improved Prism algorithm are used to find out the correlation among user traits,type of game interaction events and user experience.The experiment results can provide references for VR designers and developers,and at the same time provide the preliminary study to standardized VR user experience evaluation.

Key words: Prism algorithm, User experience, User traits, Virtual reality, VR interaction
