IntroductionHere are some examples of tracking : http://cb.nowan.net/blog/state-of-vr/state-of-vr-devices/#tracking There are also cheap ways : - Gametrak ( position only, should be in the next VRPN release ) - SpacePoint Fusion ( orientation only, should be in the next VRPN release ) - Vuzix VR 920 integrated tracker ( orientation only ) - Camera based tracking (Wiimote, AR Patterns, Rigid body tracking....) - PS3 Move (soon Sony will release a PC based SDK) - TrackIR - Gyromouse - Freespace (not tested but seems interesting, and already in VRPN) - Razer Hydra (not released yet but seems interesting) - < invent your own ! > As all applications have to use VRPN, there has to be a VRPN driver for the trackers your using. If there aren't any driver yet, you are invited to write it and share it ! Useful VRPN servers- Wiimote head-tracking : by Ryan Pavlik. Perfect for tracking your head in front of a screen. - Microsoft Kinect SDK VRPN server - Wiiuse VRPN server |
