摘　　要：针对大型产品虚拟装配环境中的场景漫游问题,提出一种简单且高效的视点运动控制策略。以认知心理学和人机工程学理论为指导,首先建立人手作业空间,然后对作业空间进行功能划分,分为对象操作区和视点漫游区,最后在功能分区的基础上建立人手运动感知与视点运动控制的映射模型。通过实验证明,操作者对大型产品进行虚拟装配的过程中,可以轻松地利用该方法实现场景漫游,进而实现虚拟环境中对象操作和场景漫游的无缝集成。A high-efficiency navigation strategy is proposed for virtual assembly environment of large-scale products. Based on the theory of cognitive psychology and ergonomics, a workspace of human hand is constructed. Then the workspace is divided into object operation space and viewpoint navigation space. Finally a motion mapping relationship between human hand and viewpoint is developed. It has been proven by experiments that the users can easily navigate the virtual environment in the virtual assembly process. So the two interactive modes, object operation and scene navigation, can be integrated seamlessly.
