Abstract
A head-mounted display device includes a see-though display providing both eyes of a user with a view of a physical object, a processor, and a non-volatile storage device holding instructions executable by the processor to: display an image that corresponds to the physical object to a first eye of the user at an offset to the physical object; display blocking light to a second eye of the user; in response to alignment user input, move a position of the image relative to the physical object; in response to completion user input, determine the inter-pupillary distance of the user; and calibrate the head-mounted display device based on the inter-pupillary distance.
