TrackIR, created by NaturalPoint Inc., is an optical motion tracking controller for Microsoft Windows.
TrackIR was initially designed as an assistive technology device for the Windows cursor control.
[citation needed] Between 2002 and the year 2005, five TrackIR camera models were released, bringing more features such as doubled frame rate and increased resolution.
However, due to the fact that older TrackIR-1 and TrackIR-2 products use software drivers which are no longer maintained, they are also incompatible with titles using the newer interface.
Additionally, one review noted that the TrackIR 4 Pro runs at a temperature which they consider more higher than normal when it is actively tracking.
