Electromagnetic tracking is 3D tracking technology that generates magnetic fields and detects them from a sensor. It is a native technology for 6DOF tracking.
It is also called just "magnetic tracking".
Magnetic tracking is natural because it preserves high frequency transients in movement, like a flick of a finger.
It was invented in about 1970 by Polhemus. Another company that has made electromagnetic tracking devices is Ascension Technologies.
The Magic Leap 1 uses magnetic tracking for its handheld controller, but in a poor form.
Examples of products include the Polhemus FASTRAK.
Neuralink researched using magnetic tracking at up to 240hz for tracking monkeys' body movements in tests.

Types
- AC magnetic tracking (Polhemus)
- pulsed DC magnetic tracking (Used by Ascension/NDI)
