摘要
为使头戴显示器用户(HMM)和非头戴显示器用户在沉浸式虚拟现实(VR)中具有相同或相似的临场感和体验,提出一种时间—空间角色的VR系统,其核心是允许两类用户获得各种不同类型体验.首先,系统将HMM用户的核心角色限制为空间角色,感知现场发生的情况.然后,快速判断做出反应,将观察到的当前情境转告至非HMM用户,以分享其临场感.最后,系统通过时间概念扩展非HMM用户的角色,通过第三人称相机视角,分析为实现目标所需的具体因素,并制定执行方法的相关决策.实验结果表明,所提系统能够为HMM和非HMM用户提供满意的临场感,并可针对每个角色提供各种体验.
Abstract
In order to make head mounted monitor(HMM)user and non head mounted monitor users have the same or similar sense of presence and experience in immersive virtual reality(VR),it is proposed a VR system based on tempo-ral and spatial roles.Its core is to allow two types of users to obtain different types of experiences.Firstly,the system limits the core role of HMM users to spatial roles,which can directly perceive the situation on the scene.Then,Bin needs to quickly judge to react and relay the observed current situation to non HMM users to share their sense of pres-ence.Finally,the system extends the role of non HMM users through the concept of time.From the perspective of the third person camera,the system analyzes the specific factors needed to achieve the goal,and makes relevant decisions on the overall implementation method.Experiments show that the proposed system can provide satisfactory presence for HMM and non HMM users,and provide various experiences for each role.
