Claim 26:
27. A method of determining distance in an AR/MR/VR display, the method comprising;
generating or providing at least one virtual object for display;
projecting into the optical waveguide combiners of a binocular optical combiner system a display image of the virtual object(s);
displaying in stereo, by the optical waveguide combiners, the display image as the virtual object(s);
capturing stereo images of the displayed virtual object(s) and at least one real object(s) using one or more optical camera(s) incorporated into each optical waveguide combiner of the binocular system, the one or more camera(s) having a field of view of the real object(s) and of displayed virtual object(s);
comparing the displayed virtual object(s) to the real object(s) using the captured stereo images
determining the binocular disparity in the stereo images;
determining the distance of the real object(s) from virtual object(s) according to the binocular disparity.
