虚拟现实（VR）在实验室技能培训中的应用正在迅速增加。在这样的应用中，用户通常需要在有限的物理空间内探索大型虚拟环境，同时完成一系列基于手的任务（例如，对象操纵）。然而，最广泛使用的基于手势的远距传送方法可能与用户的手部操作冲突，并导致更高的认知负荷，从而负面地影响他们的训练体验。为了缓解这些限制，我们设计并实现了一种名为ManiLoco的移动方法，以实现免提交互，从而避免其他任务的冲突和中断。用户可以通过在看物体的同时向物体迈出一步来传送到远程物体的位置。我们评估了ManiLoco，并在一个有16名参与者的受试者内实验中将其与最先进的Point & Teleport进行了比较。结果证实了我们的脚和头为基础的方法的可行性，更好地支持并发对象操作在VR训练任务。此外，我们的运动方法不需要任何额外的硬件。它完全依赖于VR头戴式显示器（HMD）和我们检测用户步进活动的实现，并且它可以作为插件轻松应用于任何VR应用程序。
The use of virtual reality (VR) in laboratory skill training is rapidly increasing. In such applications, users often need to explore a large virtual environment within a limited physical space while completing a series of hand-based tasks (e.g., object manipulation). However, the most widely used controller-based teleport methods may conflict with the users' hand operation and result in a higher cognitive load, negatively affecting their training experiences. To alleviate these limitations, we designed and implemented a locomotion method called ManiLoco to enable hands-free interaction and thus avoid conflicts and interruptions from other tasks. Users can teleport to a remote object's position by taking a step toward the object while looking at it. We evaluated ManiLoco and compared it with state-of-the-art Point & Teleport in a within-subject experiment with 16 participants. The results confirmed the viability of our foot- and head-based approach and better support concurrent object manipulation in VR training tasks. Furthermore, our locomotion method does not require any additional hardware. It solely relies on the VR head-mounted display (HMD) and our implementation of detecting the user's stepping activity, and it can be easily applied to any VR application as a plugin.
