Occlusion-capable augmented reality display using cloaking optics
First Claim
1. An augmented reality (AR) system, comprising:
- a first focusing element configured to receive light defining a view of a user environment;
a mask display screen configured to occlude a selected portion of the view as the received light passes through the mask display screen;
an AR display screen configured to generate AR content that appears in the view at a location of the occluded selected portion; and
a second focusing element configured to emit the view containing the AR content to a user, wherein a spacing between the first and second focusing elements is set such that when the received light defining the view exits the second focusing element, the exiting light propagates in respective first directions that are the same as respective second directions of the received light entering the first focusing element,wherein the spacing between the first and second focusing elements maintains, at least in part, a perspective of the user at a location of an eye of the user viewing the view provided by the second focusing element, wherein the spacing between the first and second focusing elements is set such that, to the perspective of the user, the first and second focusing elements do not redirect the received light from the first directions as the received light travels through the AR system.

Abstract
Embodiments herein describe AR systems that provide occluded AR content to a user while maintaining the perspective of the user. In one embodiment, the AR system includes an optical cloak that contains a mask display device and an AR display device and one or more focusing elements for focusing light captured from the user'"'"'s environment. As the light enters the optical cloak, the mask display device occludes a portion of the user'"'"'s view to generate a black silhouette. The AR system then combines AR content displayed by the AR display device with the image of the environment such that the location of the AR content overlaps with the location of the black silhouette. Furthermore, the spacing and characteristics of the focusing elements is set to maintain the perspective of the user as the light passes through the optical cloak.

7. An AR system, comprising:
-
a first focusing element configured to receive light defining a view of a user environment; a mask display screen configured to occlude a selected portion of the view as the received light passes through the mask display screen; an AR display screen configured to generate AR content that appears in the view at a location of the occluded selected portion; a second focusing element configured to emit the view containing the AR content to a user, wherein a spacing between the first and second focusing elements maintains, at least in part, a perspective of the user at a location of an eye of the user viewing the view provided by the second focusing element, wherein the spacing between the first and second focusing elements is set such that, to the perspective of the user, the first and second focusing elements do not redirect light received at the first focusing element as the received light travels through the AR system; and a plurality of reflective surfaces configured to redirect an optical path of the received light as the received light travels between the first and second focusing elements, wherein the plurality of reflective surfaces fold the optical path. - View Dependent Claims (8, 9, 10, 11)

12. A method, comprising:
-
receiving light defining a view of a user environment at a first focusing element; occluding a selected portion of the view to produce a silhouette of AR content in the view; introducing the AR content into the view at the location of the silhouette; outputting the view containing the AR content at a second focusing element, wherein a spacing between the first and second focusing elements maintains, at least in part, a perspective of a user at a location of an eye of the user viewing the view provided by the second focusing element, wherein the spacing between the first and second focusing elements is set such that, to the perspective of the user, the first and second focusing elements do not redirect light received at the first focusing element as the received light travels between the first and second focusing elements. - View Dependent Claims (13, 14, 15, 16)
