视觉作为人认知环境的主要信息通道,在空间遥操作任务中有极其重要的作用。本研究面向空间站机械臂遥操作任务,通过对24名被试进行机械臂遥操作模拟平台实验,探索不同程度空间立体信息缺失对机械臂遥操作绩效、脑力负荷、距离感知和情境意识的影响,剖析不同立体信息在遥操作过程中的作用。实验结果表明:局部立体信息对提高遥操作任务完成率、减少撞击操作等指标有重要作用;而全局立体信息更有利于减少机械臂冗余行走距离和限位操作次数;两者对脑力负荷水平的降低有显著影响,而对距离估计偏差和情境意识水平影响不显著。因此,根据不同任务类型选取合适的立体信息补偿,从多个角度完善立体信息的呈现对于保障遥操作任务的顺利进行具有重要意义。
As the main information channel of human cognition environment, vision plays an extremely important role in the task of space teleoperation. In order to solve the teleoperation task of robotic arm of space station, this study tested 24 robotic arm teleoperation simulation platform to explore the effect of spatial information loss on teleoperation performance, mental workload, distance perception and situational awareness, Analysis of the role of different stereo information in teleoperation. The experimental results show that the local stereo information plays an important role in improving the completion rate of teleoperation tasks and reducing the impact operation. The global stereo information is more conducive to reducing the redundant walking distance and the number of limit operations. But had no significant effect on distance estimation and situational awareness. Therefore, it is of great significance to improve the presentation of the three-dimensional information from multiple perspectives for the purpose of ensuring the smooth operation of the teleoperation task by selecting suitable three-dimensional information compensation according to different task types.
