Abstract

In this study, we present a biomimetic mixed reality (MR) wearable device that enables users to experience the dynamic multiphase pressure of avatar locomotion within metaverse environments governed by flow physics. Our research focuses on developing a biomimetic crossed-four-bar linkage mechanism inspired by human cruciate ligaments to facilitate smooth and realistic gait patterns. The engineered mechanism achieves enhanced gait stability, demonstrating a minimal error margin of 2.8% in knee joint motion, and regulates torque output to a maximum of 5 N-m using geared motor reducers. The study successfully simulated diverse flow pressure scenarios and subsequently translated these simulations into real-time torque feedback, enhancing user interaction and system responsiveness. This innovative approach holds significant potential in creating adaptive MR environments for virtual platform applications, such as digital underwater gait rehabilitation, flow-resistive military exercises, and exploratory pre-training for space travelers.

在这项研究中，我们介绍了一种仿生混合现实（MR）可穿戴设备，它能让用户体验到在受流动物理学支配的元宇宙环境中，化身运动的动态多相压力。我们的研究重点是受人类十字韧带的启发，开发一种生物仿真交叉四杆连杆机构，以促进流畅、逼真的步态模式。该工程机构增强了步态稳定性，膝关节运动的最小误差率为 2.8%，并利用齿轮电机减速器将扭矩输出调节到最大 5 N-m。这项研究成功模拟了各种流动压力情况，随后将这些模拟转化为实时扭矩反馈，增强了用户互动和系统响应能力。这种创新方法在为虚拟平台应用创建自适应磁共振环境方面具有巨大潜力，例如数字水下步态康复、抗流军事演习和太空旅行者的探索性预培训。
