Simulation of Human Movement in Zero Gravity

Area of Science:

• Biomechanics
• Space Medicine
• Human Movement Analysis

Background:

• Expanding manned space missions necessitate understanding zero gravity's effects on human movement.
• Current methods for simulating space biomechanics can be complex and costly.

Purpose of the Study:

• To introduce a novel, cost-effective framework for simulating human movement in zero gravity.
• To apply Microsoft's Azure Kinect body tracking technology for motion input generation.
• To validate simulation realism using principles of momentum conservation.

Main Methods:

• Utilized Azure Kinect for motion capture.
• Integrated motion data into OpenSim for zero gravity simulations.
• Tested various movements including rotations, locomotion, coordination, and martial arts.
• Validated results against angular and linear momentum conservation.

Main Results:

• The framework successfully simulated human movements in a simulated zero gravity environment.
• Complex, full-body coordination tasks showed limitations in zero gravity.
• Findings suggest potential for device-free astronaut exercise routines.
• Insights gained into the feasibility of hand-to-hand combat in space.

Conclusions:

• The developed framework offers practical potential for space mission planning and research.
• Challenges remain in distinguishing simulation artifacts from true zero gravity effects.
• Further refinement is recommended for comprehensive validation and application.
