An '''electromagnetic tracking system''' is a system that performs [[electromagnetic tracking]], which tracks an object in a space using [[electromagnet]]s. It can be used to track the position and orientation of a [[head-mounted display]]. It can also be used to track handheld input devices. Examples of electromagnetic tracking systems are the [[Polhemus Viper]] and the [[Razer Hydra]].

They can simply be called magnetic tracking systems.

Electromagnetic tracking systems typically use three coils for the X, Y, and Z directions, in [[ICSA]].

Electromagnetic tracking systems typically use three coils for the X, Y, and Z directions. There is a base station and a receiver. The base station generates the magnetic field, and the receiver senses it.
