An electromagnetic tracking system is a system that tracks an object in a three-dimensional space using electromagnets. It can be used together 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 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.
Electromagnetic tracking systems must be calibrated before they can be used.
Magnetic tracking systems are typically expensive.
Examples
Construction
There must be an analog to digital converter (ADC), magnet wire (enameled wire), and a microcontroller.
