Abstract
A head-mounted display device is disclosed that includes an at least partially see-though display, a processor, and a non-volatile storage device holding instructions executable by the processor to: select an image that corresponds to a physical object viewable by the user; display the image at a perceived offset to the physical object; in response to alignment user input, move a perceived position of the image relative to the physical object; output an instruction to provide completion user input when the image appears to align with the physical object; when the completion user input is received, determine the inter-pupillary distance of the user; and calibrate the head mounted display device based on the inter-pupillary distance.
