Abstract
A calibration platform may display, via an optical see-through head-mounted display (OST-HMD), a virtual image having at least one feature. The calibration platform may determine, based on information relating to a gaze of a user wearing the OST-HMD, that the user performed a voluntary eye blink to indicate that the at least one feature of the virtual image appears to the user to be aligned with at least one point on the three-dimensional real-world object. The calibration platform may record an alignment measurement based on a position of the at least one point on the three-dimensional real-world object in a real-world coordinate system based on a time when the user performed the voluntary eye blink. Accordingly, the alignment measurement may be used to generate a function providing a mapping between three-dimensional points in the real-world coordinate system and corresponding points in a display space of the OST-HMD.
