Electromagnetic tracking is 3D tracking technology that uses magnetic fields to track an object in 6 degrees of freedom. It can be extremely precise if done right.
One company that makes electromagnetic tracking devices is Polhemus.
The Magic Leap 1 used a poor form of EM tracking for its handheld controller.
EM tracking was used by Neuralink to track monkey muscle movements internally to gather data.
AC magnetic tracking
AC magnetic tracking uses fluctuating magnetic fields generated by a source and picked up by a sensor. The sensor can be about 2mm thick.
The fastest electromagnetic tracking system in the world is the Polhemus Viper 16, which tracks up to 960hz. This is much faster than the 100hz of all existing consumer VR systems. It provides a more natural feel.
