Fastrak is a 3D magnetic tracking system from Polhemus. Its name refers to the capability of fast tracking.
FastTrak was used in most VPL systems. It was also used in the first generation Virtuality systems.[1]
It is a 6DOF tracking system, meaning it tracks position and rotation.[2]
The sources and sensors for the fastrak are compatible with Polhemus Patriot SEUs.
The price was about $6000.[2]
