Performance Evaluation of Motion Tracking Methods: Magnetic Induction and HF RFID

Human motion tracking has broad applicability, and currently, various approaches are available for its deployment. Wearable sensors and vision-based methods are among the most commonly used techniques that still face challenges in terms of accuracy, privacy, coverage, and cost. The magnetic induction (MI) system is a new approach based on inductive coupling, representing motions via variation in the MI signals. In this work, we present the performance analysis of the MI system and compare its accuracy with a high frequency (HF) radio frequency identification (RFID) system using experimental measurements in 3D motion tracking.
