Polhemus Liberty 240 Hz No
Polhemus Viper 4 240 Hz No Optional about 0.5 mm for XYZ position[1] about 5 feet
Polhemus Viper 8 and Viper 16 960 Hz No Optional
Polhemus Patriot 60 Hz No
Polhemus 3SPACE Isotrak II 60 Hz No
Polhemus FASTRAK 120 Hz No
Razer Hydra 60 Hz Yes Yes
Sixense STEM (Unreleased) 240 Hz Yes Yes
