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]
Specs[edit]
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]
