外骨骼是很有前途的物理增强工具，已显示出改变土木工程操作的潜力，但由于不同职业领域的外骨骼设计，功能和指导方针的多样性，培训本身就具有挑战性。传统的动手外骨骼训练是耗时且资源广泛的，而虚拟训练（诸如视频演示）对于外骨骼所需的运动技能学习是无效的。目前尚不清楚增强的虚拟环境是否可以促进外骨骼训练的运动技能获得。本文提出了一种基于触觉的感觉传递方法，通过虚拟现实中的被动触觉系统将专家外骨骼用户的自我中心运动体验迁移到另一个新手用户。30例人体实验结果表明，基于触觉的感觉传递方法显著提高了外骨骼训练中的运动学习率，验证了虚拟训练在运动密集型任务中的有效性。所提出的基于触觉的感觉传递方法可以丰富具身运动学习体验，从而有利于运动训练在工作中的更广泛应用。值得探索的是在未来的最佳触觉配置，以增强实施，同时避免潜在的过度依赖反馈。
Exoskeletons are promising physical augmentation tools that have shown potential to transform civil engineering operations, but the training is inherently challenging due to the diverse exoskeleton designs, functions, and guidelines across different occupational sectors. Traditional hands-on exoskeleton training is time-consuming and resource-extensive, while virtual training, such as video demonstrations, is ineffective for motor skill learning needed for the exoskeleton. It is unknown if an enhanced virtual environment can facilitate motor skill gaining for exoskeleton training. This paper proposes a haptic-based sensation transfer approach that migrates the egocentric motor experience of an expert exoskeleton user to another novice user, via a passive haptic system in virtual reality. The result of a human-subjects experiment (n= 30) showed that the proposed haptic-based sensation transfer approach significantly improved the motor learning rate in exoskeleton training, and validated the effectiveness of virtual training for even motor-intensive tasks. The proposed haptic-based sensation transfer approach can enrich the embodied motor learning experience and thus can benefit broader applications of motor training at work. It is worth exploring optimal haptic configurations in the future, to enhance embodiment whilst avoiding potential over-reliance on feedback.
