Physics-Informed Ground Reaction Force Estimation: Bridging Motion Capture and Biomechanics Understanding Human Movement Through Physics Human motion analysis has revolutionized fields from sports science to robotics. At its core lies the critical need to understand ground reaction forces (GRF) – the forces exerted by the ground on our bodies during movement. Traditional methods rely on specialized equipment like force plates, but these lab-bound tools limit real-world applications. This article explores a breakthrough approach that calculates GRF using only motion capture data and fundamental physics principles. The Challenge: Why Force Plates Fall Short Force plates measure ground reaction forces by detecting …
