Abstract: This paper presents an approach of interaction modeling in virtual reality. A new modeling tool VRTool is designed, and topology model(VRTP) and Visual Training Navigation model(VTN) are proposed to solve the problems of data source of location coordinates and linear pace mutation, which can set up interaction relation of man-machine and three-dimension navigation movement conveniently. The experimental result demonstrates the usability of this approach, and a new thought for interaction modeling is provided to the development of VR modeling tool.

摘要： 给出一种虚拟现实交互建模的方法。设计了一种新型建模工具VRTool，提出了交互性建模的拓扑模型和视角跟踪导航模型，解决了交互建模的定位坐标数据源问题和线性速度突变问题，其优点在于能够方便人与三维模型之间交互关系以及三维导航运动模型的建立。实验结果表明了该建模方法的可靠有效性，为虚拟现实建模工具的发展提供了新的思路。
