NaturalPoint TrackIR Users Manual   6. Gaming Environment Distance between the TrackIR and the user The optimum distance between the user and the TrackIR is 24-36 inches. Using the TrackIR within this range will achieve the best balance between range of motion and tracking precision. We recommend having no more than 4 feet between the reflective target and the front of the TrackIR. Lighting We recommend turning off or dimming lights in the room and removing any highly reflective materials that are directly in the view of the TrackIR’s camera. You can easily check what the TrackIR’s camera is seeing by opening the Camera View.
