Claim 17:
18. A method of registering a VR/AR/MR display, the method comprising providing at least one virtual object for display;
projecting into an optical waveguide combiner a display image of the virtual object(s);
displaying, by the optical waveguide combiner, the display image as the virtual object(s);
capturing an image of the displayed virtual object(s) and real world scene using one or more optical camera(s), the camera(s) being optically coupled to an output of the optical waveguide combiner and having a field of view of the real world scene and of the displayed virtual object(s);
comparing, using the captured image, the virtual object(s) to at least one real object of the real world scene;
determining a registration error between the virtual object(s) and the real object(s) based on the comparison;
adjusting the virtual object(s) being displayed to substantially correct the registration error.
