We describe a fiducial marker tracking method for an augmented reality system. Square markers are used for fast precise registration and a camera model that includes a distortion function is also employed. We also describe a system calibration method. In order to display virtual objects on a head mounted display (HMD) screen the relationships between the HMD, human eyes and head mounted camera are very important. Camera calibration is also vital for accurate marker tracking. We describe a novel HMD calibration technique which does not require much effort from the user and provides very good usability. With good calibration our tracking method provides very accurate tracking and runs at 30 frames/sec on a SGI Octane computer.
