Electromagnetic tracking

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 can be implemented in an electromagnetic tracking system.

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.
