SELECTIVE OCCLUSION SYSTEM FOR AUGMENTED REALITY DEVICES
First Claim
1. A near-eye display system, comprising:
- a see-through display;
an image source configured to produce images for display on the see-through display;
a background light sensor configured to sense a brightness of a real-world background;
a selective background occluder comprising a first liquid crystal panel and a second liquid crystal panel spaced from the first liquid crystal panel, the first liquid crystal panel and the second liquid crystal panel being positioned between a common pair of polarizers; and
a computing device comprising a logic subsystem and a storage subsystem storing instructions executable by the logic subsystem to;
determine a shape and a position of an occlusion area based upon a virtual object to be displayed on the see-through display,obtain a first birefringence pattern for the first liquid crystal panel and a second birefringence pattern for the second liquid crystal panel based upon the shape and the position of the occlusion area,produce the occlusion area by applying the first birefringence pattern to the first liquid crystal panel and the second birefringence pattern to the second liquid crystal pattern, anddisplay the virtual object in a location visually overlapping with the occlusion area.

Abstract
Examples are disclosed that relate to selectively dimming or occluding light from a real-world background to enhance the display of virtual objects on a near-eye display. One example provides a near-eye display system including a see-through display, an image source, a background light sensor, a selective background occluder comprising a first liquid crystal panel and a second liquid crystal panel positioned between a pair of polarizers, and a computing device including instructions executable by a logic subsystem to determine a shape and a position of an occlusion area based upon a virtual object to be displayed, obtain a first and a second birefringence pattern for the first and the second liquid crystal panels, produce the occlusion area by applying the birefringence patterns to the liquid crystal panels, and display the virtual object in a location visually overlapping with the occlusion area.

10. On a near-eye display system comprising a see-through display and a selective background occluder comprising a first liquid crystal panel and a second liquid crystal panel positioned between a common pair of polarizers, a method of selectively dimming light from one or more areas of a real-world background, the method comprising:
-
determining a shape and a position of an occlusion area based upon a virtual object to be displayed on the see-through display; obtaining a first birefringence pattern for the first liquid crystal panel and a second birefringence pattern for the second liquid crystal panel based upon the shape and the position of the occlusion area; producing the occlusion area by applying the first birefringence pattern to the first liquid crystal panel and the second birefringence pattern to the second liquid crystal pattern, and displaying the virtual object in a location visually overlapping with the occlusion area. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A near-eye display system, comprising:
-
a see-through display; an image source configured to produce images for display on the see-through display; a background light sensor configured to sense a brightness of a real-world background; a selective background occluder comprising a first liquid crystal panel and a second liquid crystal panel spaced from the first liquid crystal panel, the first liquid crystal panel and the second liquid crystal panel being positioned between a common pair of polarizers; and a computing device comprising a logic subsystem and a storage subsystem storing instructions executable by the logic subsystem to determine a shape of an occlusion area based upon a virtual object to be displayed via the see-through display, and operate the first liquid crystal panel and the second liquid crystal panel such that light passing through a first pixel of the first liquid crystal panel and a first pixel of the second liquid crystal panel is attenuated differently than light passing through the first pixel of the first liquid crystal panel and a second pixel of the second liquid crystal panel. - View Dependent Claims (19, 20)
