Optical see-through head-mounted displays (HMDs)are less commonly used because they are difficult toaccurately calibrate. In this article, we report a user studyto compare the accuracy of 4 variants of the SPAAMcalibration method. Among the 4 variants, Stylus-markercalibration, where the user aligns a crosshair projected inthe HMD with a tracked stylus tip, achieved the mostaccurate result. A decomposition and analysis of thecalibration matrices from the trials is performed and thecharacteristics of the computed calibration matrices areexamined. A physiological engineering point of view isalso discussed to explain why calibrating optical see-throughHMD is so difficult for users.
