In a controlled environment, magnetic tracking’s accuracy is good. However, it can be influenced by interference from conductive materials near the emitter of sensors, from other magnetic fields generated by other devices and from ferromagnetic materials in the tracking area. | In a controlled environment, magnetic tracking’s accuracy is good.

Magnetic tracking can be AC or DC. Magnetic tracking is great because it doesn't need a Kalman filter. It is much higher quality than all other tracking methods, but there are constraints on its usage, like how it cannot be used in environments with a lot of metal due to interference. | |||
