Augmented reality apparatus
First Claim
1. An apparatus for providing a person with an augmented reality responsive to a scene that the person views, the apparatus comprising:
- a photosensor that images light incident on the photosensor;
a light projector;
a controller that controls the projector to project light that generates an augmenting virtual image (AVI) that is not projected onto the scene and having markers corresponding to homologous features in the scene;
optics that directs light from the scene and light projected by the projector to form a first combined image on the person'"'"'s retina comprising an image of the scene overlaid by the AVI, and a second combined image comprising an image of the scene overlaid by the AVI on the photosensor;
wherein the controller configures the AVI responsive to the second combined image so that the markers in the first combined image are substantially coincident with the corresponding homologous features of the scene comprised in the first combined image.

Abstract
An embodiment of the invention relates to an apparatus and related methods for providing a person with an augmented reality, the apparatus comprising: a projector that projects light that generates an augmenting visual image (AVI); optics that directs to a camera a portion of the projected light and a portion of light arriving from a scene so that a combined image comprising an image of the scene and the AVI are generated in a photosensor in the camera; and a controller that processes the combined image to compare positions of homologous features in the image of the scene with positions of corresponding location markers in the AVI, and renders an adjusted AVI based on the comparison, so that the location markers and the corresponding homologous features are substantially coincident in the combined image.

12. A method for providing a person with an augmented reality, the method comprising:
-
rendering an augmenting visual image (AVI) comprising location markers corresponding to selected homologous features in a scene; projecting the AVI, wherein the AVI is not projected to the scene; directing the AVI and an image of the scene to the person'"'"'s retina and a photosensor; capturing the AVI and the image of the scene; comparing positions of the homologous features in the image of the scene with positions of the corresponding location markers in the AVI; rendering an adjusted AVI in which the location markers are substantially coincident with the corresponding homologous features in the capture scene image; and projecting the adjusted AVI, wherein the AVI is not projected to the scene; and directing the adjusted AVI and the image of the scene to the person'"'"'s retina and the photosensor. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)

20. An apparatus for providing a person with an augmented reality responsive to a scene that the person views, the apparatus comprising:
-
a photosensor; a light projector that projects light that generates an augmenting virtual image (AVI) that is not projected onto the scene; optics comprising a partially reflecting flat mirror situated between a scene and the person'"'"'s retina and also between the projector and the photosensor, the partially reflecting flat mirror being configured to direct portions of the light from the scene to form an image of the scene on the person'"'"'s retina and on the photosensor, and to direct portions of the light from the projector to form the AVI on the person'"'"'s retina and on the photosensor so that the image of the scene is overlaid by the AVI on the retina and on the photosensor. - View Dependent Claims (21)
