立体信息不同缺失水平下基本认知能力在遥操作任务中的作用研究

Study on Effects of Basic Cognitive Abilities on Teleoperation Tasks under Various Lacking Levels of 3D Information

针对具体的遥操作任务中与遥操作相关的认知功能在不同立体信息缺失水平下对操作绩效、情境意识水平的影响,对24名受试者开展机械臂遥操作模拟任务实验和6项基本认知能力测试,采用相关性分析方法分析了各项认知能力在遥操作任务中的作用。试验结果表明,空间能力、运动控制能力和持续注意水平与任务的完成率以及操作的安全性、高效性紧密相关;注意分配能力、心理旋转能力在局部立体信息缺失的情境下,对保持机械臂遥对接任务的各项绩效指标的稳定、保障任务的顺利完成作用显著。因此,根据任务要求以及航天员自身特点有针对性地开展认知能力训练,合理分配在轨任务,有利于提高训练效果、保障在轨任务的顺利完成。

Aiming at the influence of teleoperation-related cognitive functions on the operation per-formance and situation awareness under various lacking levels of 3 D information in specific teleopera-tion tasks, a 24-volunteers experiment was conducted including the teleoperation simulation task ex-periment and 6 sections of basic cognitive tests. The effect of the cognitive ability on the teleopera-tion task was analyzed using the correlation analysis method. The results showed that：the spatial a-bility, the motion control ability and the sustained attention level were closely related to the task completion rate and the operation security and efficiency; the attention distribution ability and the mental rotation ability were significant to keep the performance indicator stable and ensure the suc-cessful completion of the teleoperation task when lacking of local stereo situation information. There-fore, carrying out the cognitive ability training according to the requirements of the task and the as-tronaut characteristics and assigning the orbit tasks rationally will be helpful to improve the training effect and ensure the successful completion of the orbit mission.
