We propose an environment for assisting in the transfer of motor skills by supporting nonverbal communication with wearable haptic technology. The proposed setting comprises a human expert and several learners, all endowed with wearable devices. Learners benefit from the automated feedback obtained via wearable technology regarding a desired move relevant to a specific motor skill. Similarly, the expert benefits from automated means to provide instructions to the learner as well as from monitoring data provided by wearable devices. We focus on tactile communication as the basis for this interaction, thus supporting users who are not able to rely on other senses that are relevant to most motor skill-related tasks, such as sight and hearing. We discuss leader-follower dance as a motor skill context in order to instantiate and validate critical components of our skill transfer environment, using accelerometers and gyroscopes as the basis for sensing movements. In this particular scenario, our approach focuses on the haptic communication elements needed to perform a leader-follower dance, assessing movements by the learners in response to the intent of the expert. In order to validate our approach, we have prototyped and conducted experiments with the three critical components of our environment that enables tactile communication between experts and learners. Our development is informed by user research conducted with expert dance teachers, through which we gathered expert dance moves that resulted in a reference database that makes up one of the components that are critical to demonstrate the potential of our proposed environment. We also implemented a tactile encoder that is used to send movement instructions to learners through the sense of touch, as well as an autonomous classifier that uses the reference database as input. Overall, our results provide a roadmap for building an environment for skill transfer using nonverbal communication based on haptic wearable devices.

我们提出了一种环境，通过使用可穿戴触觉技术支持非语言交流来协助运动技能的传递。拟议的设置包括一名人类专家和一些学习者，他们都拥有可穿戴设备。学习者将从通过可穿戴技术获得的有关特定运动技能的所需动作的自动反馈中受益。同样，专家将从自动方式向学习者提供指令以及从可穿戴设备提供的监视数据中受益。我们将触觉交流作为这种互动的基础，从而为无法依赖与大多数与运动技能相关的任务（例如视觉和听觉）相关的其他感觉的用户提供支持。我们将领导者跟随舞蹈作为一种运动技能来讨论，以便使用加速度计和陀螺仪作为感测动作的基础来实例化和验证我们的技能传递环境的关键组成部分。在这种特定情况下，我们的方法重点在于执行领导者跟随舞蹈所需的触觉交流元素，并根据专家的意图评估学习者的动作。为了验证我们的方法，我们对环境的三个关键组成部分进行了原型设计和实验，从而使专家和学习者之间可以进行触觉交流。我们的发展得益于与专业舞蹈老师进行的用户研究，通过这些活动，我们收集了专家级的舞蹈动作，从而形成了一个参考数据库，该数据库构成了对于证明我们建议的环境的潜力至关重要的组件之一。我们还实现了一种触觉编码器，该触觉编码器用于通过触觉向学习者发送运动指令，以及使用参考数据库作为输入的自主分类器。总体而言，我们的结果为使用基于触觉可穿戴设备的非语言交流构建技能转移环境提供了路线图。
