Abstract
Embodiments are disclosed that relate to calibrating a predetermined eye location in a head-mounted display. For example, in one disclosed embodiment a method includes displaying a virtual marker visually alignable with a real world target at an alignment condition. At the alignment condition, image data is acquired to determine a location of the real world target. From the image data, an estimated eye location relative to a location of the head-mounted display is determined. Based upon the estimated eye location, the predetermined eye location is then calibrated.
