我们介绍了VR Strider，一种新颖的用于坐式虚拟现实(VR)体验的运动用户界面(LUI)，它将用户腿部的自行车生物力学映射为虚拟步行动作。其核心思想是将迷你健身自行车上的踏板运动转换为虚拟化身的相应行走动画，同时提供基于音频的虚拟地面接触触觉反馈。在路径整合任务中，我们从任务绩效、空间认知、虚拟现实疾病、现场感、可用性和舒适性等方面对LUI和我们的新型转向锚旋转控制方法进行了实验评估。结果表明，与其他已有的移动技术相比，VR漫步在参与者的角度和距离估计、临场感和舒适感方面具有显著的积极影响，如隐形运输和基于操纵杆的导航。一项验证性研究进一步表明，对于依赖踏板的虚拟车辆来说，同步化身动画是必要的。
We introduce VR Strider, a novel locomotion user interface (LUI) for seated virtual reality (VR) experiences, which maps cycling biomechanics of the user's legs to virtual walking movements. The core idea is to translate the motion of pedaling on a mini exercise bike to a corresponding walking animation of a virtual avatar while providing audio-based tactile feedback on virtual ground contacts. We conducted an experiment to evaluate the LUI and our novel anchor-turning rotation control method regarding task performance, spatial cognition, VR sickness, sense of presence, usability and comfort in a path-integration task. The results show that VR Strider has a significant positive effect on the participants' angular and distance estimation, sense of presence and feeling of comfort compared to other established locomotion techniques, such as teleportation and joystick-based navigation. A confirmatory study further indicates the necessity of synchronized avatar animations for virtual vehicles that rely on pedalling.
