Evaluation of rotation correction techniques for electromagnetic position tracking systems

Electromagnetic position tracking devices are an integral part of many modern virtual reality systems. However, they have an inherent accuracy problem due to the dependence on the local electromagnetic field that can be easily distorted by a presence of magnetically active elements near the tracker's transmitter or receiver. Several analytical techniques have been proposed to overcome this limitation, however none of them is particularly good with the correction of rotation. In this work, we investigate various rotation correction algorithms in an attempt to identify the one that is most accurate and reliable.
