NaturalPoint TrackIR Users Manual version 4.0.020   6 Tips and Tricks 6.1 Gaming Environment The TrackIR is designed to work in a wide variety of conditions, and the current generation of TrackIR hardware is more robust and reliable than ever before. There are, however, a number of things that you can do to optimize the TrackIR’s performance: Distance between the TrackIR and the user : The optimum distance between the user and the TrackIR in Dot tracking mode is 18-24 inches, in Vector tracking mode the optimum distance is 24-36 inches. Using the TrackIR within these ranges 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 Tracking Window in the TrackIR software, for details please see Section 5.5.5   6.2 Reflective material The TrackIR ships with 26 reflective dots which are designed to be placed on a hat, a headset, a pair of glasses, or directly on your forehead. There are a number of alternatives to these dots, including NaturalPoint’s TrackHAT. Here are a few tips from the pros: Use one of the larger square dots The greater the distance between the reflective material and the center of rotation (in most cases the center of your head) the more accurate and sensitive the TrackIR will be. Place the dot on a rounded surface like a small wooden ball and mount this to your hat or visor. Additional dots, TrackHats and raw Reflective Material can from our web site at www.trackir.com
