Patent number: 11887263Abstract: In one embodiment, a computing device may determine a virtual content to be displayed with a scene of a real-world environment. The device may generate an image depicting the virtual content. Using one or more sensors, the device may detect characteristics of the scene of the real-world environment. Based on the image and the characteristics of the scene, the device may determine that a visual enhancement is to be applied to the virtual content depicted in the image to enhance a contrast between the depicted virtual content and the scene. The device may generate a visually-enhanced image depicting the virtual content by applying the visual enhancement to the virtual content depicted in the image. The device may display the visually-enhanced image of the virtual content on a display of the computing device, wherein the scene of the real-world environment is visible through the display.Type: GrantFiled: July 8, 2022Date of Patent: January 30, 2024Assignee: Meta Platforms Technologies, LLCInventors: Charlene Mary Atlas, Romain Bachy, Kevin James MacKenzie, Nathan Matsuda, Thomas Scott Murdison, Ocean Quigley, Jasmine Soria Sears

Patent number: 11428977Abstract: A configurable occluder/dimmer for a near-eye display includes an array of polarization rotators and a polarization-selective scatterer downstream of the array of polarization rotators. The array of rotators and the polarization-selective scatterer are disposed between a pair of polarizers. The polarization-selective scatterer only scatters light at one of two orthogonal polarizations, thereby enhancing the achieved extinction ratio of the configurable occluder/dimmer. The configurable occluder/dimmer may be used in the near-eye display to provide occlusion effects rendering added virtual objects opaque, and/or to equalize contrast of the generated virtual imagery across the field of view of the display.Type: GrantFiled: April 5, 2021Date of Patent: August 30, 2022Assignee: Meta Platforms Technologies LLCInventors: Nathan Matsuda, Douglas Robert Lanman, Afsoon Jamali, Jasmine Soria Sears, Oleg Yaroshchuk, Alireza Moheghi
