TrackIR is an optical motion tracking game controller for Microsoft Windows created by NaturalPoint Inc.. TrackIR tracks head motions with up to six degrees of freedom (6DOF) in later models, allowing handsfree view control for improved game immersiveness and situational awareness. Head position and orientation are measured by a purpose-built video camera, mounted on top of the user's monitor, which observes invisible infrared (IR) light (hence the name) reflected or emitted by markers on a rigid model worn by the user. TrackIR software is used to access and control the camera, as well as adjust tracking and manage game profiles. The ratio of actual head movement to virtual head movement can be changed, allowing the virtual head to turn 180 degrees whilst the user still looks at the monitor.
NaturalPoint have maintained the possibility of TrackIR eventually entering the video game console market.
The original TrackIR product was an affordable assistive technology device used for Windows cursor control. An early customer provided feedback to NaturalPoint that the product could be used in some flight simulators. This prompted NaturalPoint to re-brand the original device as SmartNav and launch a new TrackIR with improved gaming features to specifically target the flight simulation market. TrackIR was embraced by PC flight simulation enthusiasts who saw it as a better alternative to a joystick hat switch for view control. The technology used in SmartNav and TrackIR was later extended to another brand called OptiTrack, creating a more affordable professional motion capture solution.
Between 2002 and 2005, five different TrackIR camera models were released with steadily improving specifications. Frame rate doubled and resolution increased substantially, resulting in more responsive and accurate tracking. In 2003 the NaturalPoint President (also the principle hardware engineer) described these improvements to the original TrackIR as, "not critical for flight and driving sims, but very important to other types of games like first person shooters."
