Claim 20:
21. A method of registering a VR/AR/MR display, the method comprising
generating or providing at least one virtual object of known size;
based on an estimated distance of at least one real object from an optical waveguide combiner, scaling the virtual object(s) for display by the optical waveguide combiner;
projecting into the optical waveguide combiner a display image of the scaled virtual object(s);
displaying, by the optical waveguide combiner, the display image as the virtual object(s);
capturing the displayed virtual object(s) and real object(s) using one or more optical camera(s), the or each camera having a field of view of the real object(s) and of the displayed virtual object(s);
comparing, using the captured image, the real object(s) to the virtual object (s);
determining a registration error between the virtual object(s) and the real object(s) based on the comparison; and
adjusting the virtual object(s) being displayed to substantially correct the registration error.
