基于虚拟手交互的航天员虚拟装配训练仿真方法

Astronaut virtual assembly training simulation based on virtual hand interaction

针对我国载人航天任务中的航天员虚拟训练需求,提出了一种基于虚拟手交互的航天员虚拟装配训练仿真方法。该方法利用Leap Motion设备采集的手部信息,构建出符合人手结构特征的虚拟手进行训练交互,提出了交互按钮设计方法和抓取规则,以某在轨装配设备的装配训练需求为依据建立虚拟装配训练系统,并设计了主、客观评价实验及其评价标准。实验结果表明,该交互按钮设计方法与抓取规则适用于航天员虚拟训练的交互要求,与传统的手册学习训练方法相比,该基于虚拟手交互的航天员虚拟装配训练方法具有更高的训练沉浸感和主观认可度,训练效率高,效果好。

Aiming at the requirements of astronaut virtual training for manned space missions of China,this paper proposed a method of astronaut virtual assembling training based on virtual hands. According to the structures of hands,it constructed virtual hands with the information from Leap Motion and proposed the method of interactive button design and the rule of grasping. This paper established a virtual assembly training system for a certain equipment assembled in orbit,and designed subjective and objective evaluation experiments and their evaluation standards. Our experiment results show that the proposed method of interactive button design and rule of grasping fit the interactive demand of astronaut virtual training,and the method of astronaut virtual assembling training based on virtual hands is more immersed,acceptable and efficient than traditional manual method.
