摘要/Abstract

摘要： 近年来,随着虚拟现实(Virtual Reality,VR)技术的逐渐成熟,我国VR产业处于高速增长的态势。虽然VR的发展为内容设计提供了许多新的可能性,但由于VR应用的设计不成熟,VR行业的从业者们仍面临着严峻的挑战,VR中的设计仍需要通过用户使用来验证是否可行。因此,用户体验(User Experience,UX)研究对于成功设计VR软件至关重要。同时,随着用户对内容质量要求的提高,VR内容是否有足够的吸引力将在很大程度上影响用户体验,决定了用户是否会进行更进一步的VR体验。因此,如何评估VR用户体验并找到影响用户体验的内容对于提高用户体验和用户黏性至关重要。目前,对VR的研究集中在硬件和软件的改善上,对内容设计的关注较少,对用户体验的评价也没有统一且明确的标准。文中尝试找出用户体验和用户特性以及VR内容之间的关联。首先,定义了4种类型的VR交互事件,并设计了一份问卷来收集测试者的用户特性及其主观评价。其次,将80名测试者分成两组,在固定的时间内体验两种类型的VR产品,在实验过程中,测试者的客观生理数据与参与实验的整个过程都被记录下来。最后,采用统计学方法和改进的Prism算法,找出了用户特性、游戏交互事件类型与用户体验之间的相关性。文中对VR用户体验规范化评估进行了初步尝试,实验结果可以为VR内容设计人员和开发人员提供参考。

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
