Abstract

A system includes a projection device configured to project images onto a receiver surface of a viewing device. The viewing device includes a screen having the receiver surface and a viewing surface opposite the receiver surface. The screen is configured to permit transmission of the images through the screen, from the receiver surface, to the viewing surface such that the images are viewable on the viewing surface. The viewing device also includes a focusing lens configured to focus the images for a user when wearing the viewing device. Further, the system includes a tracking system configured to determine a location and orientation of the receiver surface of the viewing device. The projection device is configured to adjust image properties of the images based at least in part on the determined location and orientation of the receiver surface.

First claim

The invention claimed is:

1 . A system, comprising:
a control system configured to generate image projection instructions based at least in part on a location and an orientation of a receiver surface; one or more projection devices, wherein the one or more projection devices are configured to project images onto at least a portion of the receiver surface based on the image projection instructions, wherein the images comprise a first image and a second image configured to combine on the receiver surface to form a blended image, and wherein the image projection instructions are generated based on a determination that the location and orientation of the receiver surface are associated with an image quality loss zone of a projection device of the one or more projection devices; and a viewing device configured to be worn by a user, the viewing device comprising:
a screen comprising the receiver surface and a viewing surface.

2 . The system of claim 1 , wherein the viewing device comprises an infrared transceiver configured to output infrared location signals to a tracking system, wherein the tracking system is configured to receive the infrared location signals and determine a location and orientation of the viewing device based at least in part on the infrared location signals.

3 . The system of claim 1 , wherein the viewing device comprises glasses configured to be worn by the user.

4 . The system of claim 1 , wherein the screen is removably mounted to the viewing device.

5 . The system of claim 1 , wherein the one or more projection devices comprise a plurality of projection devices configured to project the images to a plurality of viewing devices, and wherein the projected images are configured to combine on respective receiver surfaces of the plurality of viewing devices.

6 . The system of claim 1 , wherein the viewing surface of the screen is disposed opposite the receiver surface, and the screen is configured to permit transmission of the blended image from the receiver surface, through the screen, to the viewing surface such that the blended image is viewable on the viewing surface.

7 . The system of claim 6 , wherein the screen comprises a rear projection material, and wherein the rear projection material is at least partially translucent such that the screen permits transmission of the blended image through the screen from the receiver surface to the viewing surface.

8 . The system of claim 6 , wherein the viewing surface comprises a surface of the screen facing toward the user such that the blended image is viewable for the user.

9 . The system of claim 6 , wherein the one or more projection devices are configured to adjust respective image properties of the images based at least in part on the image projection instructions to form the blended image.

10 . The system of claim 9 , wherein the image properties comprise a distortion, an offset, a scale, or some combination thereof.
