Electromagnetic tracking system
An electromagnetic tracking system is a system that performs electromagnetic tracking, which tracks an object in a space using electromagnets. It can be used to track the position and orientation of a head-mounted display. It can also be used to track handheld control peripherals. Examples of electromagnetic tracking systems are the Polhemus Viper and the Razer Hydra.
Electromagnetic tracking systems typically use three coils for the X, Y, and Z directions, in Industry Standard Coil Architecture, which is three orthogonal coils of wire, for example, in the Polhemus TX2.
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.
Commercial magnetic tracking systems usually cost thousands of dollars.
A trihedral source can be used.[1]

There must be an analog to digital converter (ADC), magnet wire (enameled wire), and a microcontroller.
