Integrating Virtual Environments with Cyber-Physical 系统ems for Robotic Rehabilitation and Human Performance Improvement

Locomotion is a fundamental human skill. Real-time sensing and feedback is a promising strategy for motion training to reconstruct healthy locomotion patterns lost due to aging or disease, 为了防止受伤. 在这项研究中, we explore human locomotion training via biomechanical modeling and a wearable haptic feedback system. 除了, a novel simulation framework for motion tracking and analysis is introduced. 这个统一的框架, implemented within the Unity environment, is used to analyze subject’s baseline and performance characteristics, and to provide real-time haptic feedback during locomotion. The framework incorporates accurate musculoskeletal models derived from 开放Sim, closed-form calculations of muscle routing kinematics and kinematic Jacobian matrices, dynamic performance metrics (i.e., 肌肉工作), human motion reconstruction via inertial measurement unit (IMU) sensors, and real-time visualization of the motion and its dynamics.

A Virtual Reality Environment with Haptic Feedback for Psychological Rehabilitation for Soccer Athletes

This research focuses on a virtual reality solution to identify possible factors that would impact self-efficacy beliefs of soccer athletes recovering from lower extremity injury while engaging in dynamic tasks within a soccer-specific virtual environment. The Psychological Response to Sport Injury Inventory measurement and brief interviews will be used after each virtual reality exposure. The virtual reality simulation will consist of three major components: virtual reality environment, motion capture of the subject, 触觉反馈. The virtual reality environment consists of three levels that vary in complexity and degree of the subject's interaction. Levels one and two will be set in a virtual physical therapy room where the subject will be introduced to virtual reality and minor dynamic interactions. Level three will be set in a virtual soccer field and will expose the subject to high dynamic interactions and decision making.

We are excited to reach out to the community and provide people of all ages and backgrounds with the opportunity to discover the potential of virtual environments to improve our lives and inspire interest in science, 技术, 工程, 和数学(STEM)主题. 我们相信每个人, from young elementary school students to young-at-heart seniors, can learn something new from the unique study of dynamic immersive environments. Potential users of our 技术, including patients with musculoskeletal disorders, professional athletes seeking to improve performance, and clinicians can especially benefit from learning about this work. 除了, we particularly encourage participation of underrepresented groups in 工程, and want to show young girls that their involvement in science, 技术, and 工程 can improve our world.
