This technology enables high frame-rate localization by measuring changes in magnetic coupling between wearable sensors, offering an absolute positioning system analogous to GPS.
Researchers at USC’s ACME lab developed the first wireless, wearable, real-time motion-tracking network using magnetic induction, enabling accurate, drift-free tracking without calibration, unlike inertial measurement based solutions.
Potential applications include remote health monitoring for physical therapy, real-time athletic performance analysis, and improved virtual reality experiences through accurate full-body motion tracking.
