Claim 7:
8. A method performed by head-mounted display device configured to be worn by a user, the method comprising:
selecting, as a calibration object, a real-world object that is currently visible in an imaged real-world scene captured by a front-facing camera of the head-mounted display device and corresponding to a view seen by the user of the head-mounted display device through an at least partially see-through display, and estimated, based on tracked motion of the head-mounted display device, to remain visible to the front-facing camera for a duration sufficient to perform a calibration procedure; and
initiating the calibration procedure using the calibration object, the calibration procedure comprising deriving a calibration transformation to be used by a processor of the head-mounted display device for calculating display positions for displaying virtual objects in alignment with corresponding real-world objects seen by the user through the display.
