It was invented in about 1970 by [[Polhemus]]. Another company that has made electromagnetic tracking gadgets is [[Ascension Technologies]].
'''Electromagnetic tracking''' is a kind of [[3D tracking]] that generates magnetic fields and detects them from a sensor. It is a technology for [[6DOF tracking]]. It can be implemented in an [[electromagnetic tracking system]]. Examples of electromagnetic tracking are the [[Magic Leap 1 controller]] and the [[Razer Hydra]].

A metallic object has to be at least a foot or two away from the tracking area so it doesn't interfere. Metallic objects cause jitter and drift.
