摘要:为了解决机械产品在虚拟现实环境中信息表达不完备、用户交互性能差的问题,以虚拟现实环境中装配信息表达的特点为基础,分析虚拟现实环境中的装配信息,并结合虚拟现实系统的需求对装配信息进行重组;同时考虑装配信息特点和虚拟现实环境的要求建立虚拟现实系统,设计实现了鼠标-键盘-菜单控制及视线控制两种交互方式,完成装配信息表达。实验结果表明,虚拟现实系统可以完整表达机械产品装配信息,合理的交互方式可以帮助虚拟现实系统实现对装配信息进行准确表达。

Abstract:The purpose of the study is to solve the problem of incomplete information expression and poor user interaction experience in the virtual reality environment of mechanical products. Based on the characteristics of assembly information in the virtual reality environment, this paper analyzes the assembly information in the virtual reality environment and reconstructs the assembly information in accordance to the requirements of the virtual reality system. At the same time, considering the characteristics of assembly information and the requirement of the virtual reality environment, a virtual reality system is established. Two interactive modes, the mouse-keyboard-menu control and the sight-line control, are designed and implemented to complete assembly information expression. The result shows that the virtual reality system can completely express the assembly information of the mechanical products, and the reasonable interaction can help the virtual reality system to accurately express the assembly information.
Key words:mechanical products;assembly information;virtual reality
