Relative Motion Analysis using Rotating Axes

460
Consider a component AB undergoing a linear motion. Along with a linear motion, point B also rotates around point A. To comprehend this complex movement, position vectors for both points A and B are established using a stationary reference frame.
However, to express the relative position of point B relative to point A, an additional frame of reference, denoted as x'y', is necessary. This additional frame not only translates but also rotates relative to the fixed frame, making it...

    Area of Science:

    • Sports Science
    • Human-Computer Interaction
    • Educational Technology

    Background:

    • Online fitness training offers convenience but faces challenges in effective motion learning.
    • Immersive virtual reality (VR) presents a potential solution for improving skill acquisition in digital fitness environments.

    Purpose of the Study:

    • To propose and validate a novel four-stage self-learning genre for VR fitness training.
    • To investigate the impact of different VR content formats (360° video vs. fully-simulated VR) on motion learning across age groups.
    • To identify user preferences and design considerations for VR fitness systems.

    Main Methods:

    • Systematic survey and proposal of a four-stage VR self-learning genre integrating learning theories and expert experience.
    • Development of progressive structures, multi-level visual cues, and a fine-grained motion analysis method for adaptive feedback.
    • Validation using a Taichi training platform, including quantitative analysis, qualitative evaluation, and case studies across different age groups.

    Main Results:

    • The proposed VR fitness genre demonstrated outstanding performance, user experience, and usability.
    • 360° video-based VR content led to better motion learning performance and user experiences compared to fully-simulated VR.
    • Specific design considerations for VR fitness systems targeting diverse age groups were identified.

    Conclusions:

    • The developed four-stage VR self-learning genre is effective for improving online fitness training and motion acquisition.
    • 360° video VR content is preferable for enhancing user experience and learning outcomes in VR fitness applications.
    • The study provides valuable insights for the development of VR systems in sports and health sectors.
