Fastrak is a 3D magnetic tracking system made by Polhemus. The name means "fast track".
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]
Specs
These are the specifications for one of the Fastrak systems.[3]
- 6 Degrees-of-Freedom.
- 1-4 Sensors.
- Update rate 120 Hz (divided by number of sensors).[2]
- Position Coverage: specified accuracy when standard receivers are located within 30 inches (76 cm) of the standard transmitter.
- All-attitude Angular Coverage.
- Static Accuracy 0.03 in. (0.08 cm) RMS for the X, Y, or Z receiver position, and 0.15° RMS for receiver orientation.
- Resolution 0.0002 inches/inch of range (0.0005 cms/cm of range), and .025°.
- Latency 4.0 milliseconds.[2]
