I. Title: From Wearable Sensor Signals to 3D Human Kinematics: Methods, Challenges, and Applications

II. Presenter: Marco Caruso, PhD, Postdoctoral Researcher & Assistant Professor, Politecnico di Torino, Italy

III. Time: 13:30–15:00, Thursday, November 5, 2026

IV. Location: RoomC216, Research Building, Qingshuihe Campus

V. Overview:

Wearable magnetic and inertial sensors enable human movement assessment beyond the laboratory, but accurate 3D position and joint angle estimation remains challenging due to sensor errors, integration drift, and orientation uncertainty. This talk presents methods for reconstructing human body kinematics from wearable sensor signals, focusing on sensor characterization, calibration, sensor fusion, and biomechanical modelling. Particular attention is given to algorithm parameter tuning, orientation estimation without external references, and anatomical and task-specific constraints for improving reconstruction accuracy. Experimental findings highlight the importance of calibration quality and algorithm optimization. Applications include daily-life gait monitoring, sports analysis, and rehabilitation, with future directions exploring the integration of inertial sensing, computer vision, and eye tracking.
