A head-mounted display provides a user with an augmented view of an object being viewed; a tracking mechanism such as a camera repeatedly determine the position and orientation of the head-mounted display relative the object being viewed; and a computer system provides information for the augmented view and repeatedly updates the augmented view of the object being viewed based on the determined position and orientation of the display. The head-mounted display may be a see-through display; it may be video-based or optical-based, and it may be monoscopic and stereoscopic. The tracking mechanism determines its position using one or more markers or beacons on the object being viewed. The markers may be active or passive, including light-emitting diodes (LEDs) that emit invisible light. |
