虚拟操作训练系统中的人机交互技术

为提高某型导弹动力系统虚拟操作训练中人机交互的沉浸性，开发了基于数据手套和空间位置跟踪仪的人机交互环境。介绍交互环境的硬件组成和工作原理，根据手的生理结构和运动特性，建立具有约束的虚拟手几何建模，采用面向对象的技术，对虚拟手的数据结构进行描述，采用放置透明包围体的方法，有效解决碰撞检测问题，对碰撞后的视觉和力觉反馈进行研究。该系统提高了该型导弹动力系统虚拟操作训练的效率。

Human-computer Interaction Technology in Virtual Operating Training System

To improve the feeling of immersion in the virtual reality operation system of some type missile, this paper proposes the human-computer interaction environments based on data-glove and orientation tracker. It discusses the structure and the principle of this system, presents the geometry modeling of virtual hand with reference to the structure and movement property of the hand, and adopts the object-oriented technology to show the data. The collision detection problem is efficiently solved by adopting the method of placing transparent bounding volume. The vision and force feedback after the collision are also studied. This system improves the efficiency in the virtual reality operation training of some type missile.
