我们提出了一个虚拟现实系统Onebody，用于在运动或体育活动训练期间进行远程姿势指导，例如武术，瑜伽或舞蹈，使用第一人称视角。该系统使用骨骼跟踪的教师和学生，呈现为虚拟化身。使用虚拟现实耳机，学生可以可视化教师化身的运动，代替他们自己的身体。Onebody提供了第一人称视角的运动指导，允许学生进入教练的身体。我们进行了一项研究，以比较Onebody在姿势匹配准确性和用户偏好方面的性能，以及提供运动指令的现有技术，包括预先录制的视频，视频会议和第三人称视角虚拟现实。结果表明，一体机提供了更好的姿势精度在提供运动指令。
We present Onebody, a virtual reality system for remote posture guidance during sports or physical activity training, such as martial arts, yoga or dance, using first person perspective. The system uses skeletal tracking of the instructor and the students, rendered as virtual avatars. Using a virtual reality headset, the student can visualise the movement of the instructor's avatar, rendered in place of their own body. Onebody provides a first person perspective of the movement instruction, allowing the student to step into the instructor's body. We conducted a study to compare the performance of Onebody in terms of posture matching accuracy and user's preference, with existing techniques of delivering movement instructions, including pre-recorded video, video conferencing and third person view virtual reality. The result indicated that Onebody offers better posture accuracy in delivering movement instructions.
