An electromagnetic tracking system is a system that 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 input devices. Examples of electromagnetic tracking systems are the Polhemus Viper and the Razer Hydra.
It does electromagnetic tracking.
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.
Commercial magnetic tracking systems usually cost thousands of dollars.
A trihedral source can be used.[1]
Examples
Construction
There must be an analog to digital converter (ADC), magnet wire (enameled wire), and a microcontroller.
