摘　　要：增强现实系统中,不同标识上虚拟物体交互行为比较单一,且大多根据标识间的距离控制交互,当系统中标识增多时,系统的运行效率将大大降低。本文将虚拟现实中的感知技术引入到系统中,为虚拟物体建立了一种基于空间距离的感知模型,将标识间的距离分级,虚拟物体对处于自己感知域内不同距离级别上的其它虚拟物体采取不同的交互行为。实验结果表明,该方法可以丰富虚拟物体的交互行为,同时满足系统实时性需求。In an augmented reality system, interactions between virtual objects on different marks are relatively unitary and maily controlled by mark distance readings. As marks in the system increase, its operating efficiency will be greatly reduced. Introducing the perception technology of virtual reality into the system, this paper establishes a perception model for virtual objects based on space distance. Distance between marks is graded so that within their perception domains, virtual objects adopt different interactions with other virtual objects at different distances. Experimental results show that this method can enrich the interaction between virtual objects and meet the real-time requirements of system.
