Uncertainty in measurement of point correspondences negatively affects the accuracy and precision in the calibration of head-mounted displays (HMD). In general, the distribution of alignment errors for optical see-through calibration are not isotropic, and one can estimate its distribution based on interaction requirements of a given calibration process and the user's measurable head motion and hand-eye...
With users always involved in the calibration of optical see-through head-mounted displays, the accuracy of calibration is subject to human-related errors, for example, postural sway, an unstable input medium, and fatigue. In this paper we propose a new calibration approach: Fixed-head 2 degree-of-freedom (DOF) interaction for Single Point Active Alignment Method (SPAAM) reduces the interaction space...
For stereoscopic optical see-through head-mounted display calibration, existing methods that calibrate both eyes at the same time highly depend on the HMD user's unreliable depth perception. On the other hand, treating both eyes separately requires the user to perform twice the number of alignment tasks, and does not satisfy the physical structure of the system. This paper introduces a novel method...
