An '''electromagnetic tracking system''' is a system that tracks an object in a three-dimensional space using [[electromagnet]]s. It is also called a magnetic tracking system. Examples are the [[Polhemus Viper]] and the [[NDI Aurora]].

An '''electromagnetic tracking system''' is a system that tracks an object in a three-dimensional space using [[electromagnet]]s. It can be used in concert with a near-eye display system or a world-fixed display. Examples of electromagnetic tracking systems are the [[Polhemus Viper]] and the [[NDI Aurora]]. They can also simply be called magnetic tracking systems.

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.
