Patent number: 11726328Abstract: The disclosure describes artificial reality (AR) systems and techniques that enable a change in focus of virtual image content without substantially changing magnification of real-world content. For example, an AR system includes a virtual image content output device, a first tunable lens on a real-world side of the virtual image content output device, a second tunable lens on an eye side of the virtual image content output device, and at least one compensating lens. The at least one compensating lens is configured to substantially eliminate magnification changes of real-world light between a real-world end of the optical system and an eye-side end of the optical system as a focal power of at least one of the first tunable lens or the second tunable lens changes.Type: GrantFiled: December 4, 2020Date of Patent: August 15, 2023Assignee: META PLATFORMS TECHNOLOGIES, LLCInventors: Marina Zannoli, Jacques Gollier

Patent number: 11016301Abstract: An auto-focus head-mounted display (HMD) dynamically generates aberration-adjusted images based on measured accommodation of user's eye(s). An aberration-adjusted image is an image distorted to correct aberrations that would otherwise occur at a retina of the user due to image light passing through optics of the HMD. The aberration-adjusted image corrects the aberrations of the HMD and “accounts” for the aberrations of the eye so that the resulting retinal image is free of optical aberrations due to the HMD but preserves correct eye optical aberrations that are correlated with a current accommodative state of the eye.Type: GrantFiled: June 3, 2019Date of Patent: May 25, 2021Assignee: Facebook Technologies, LLCInventors: William Aaron Nicholls, Marina Zannoli, Douglas Robert Lanman, Nicholas Daniel Trail

Patent number: 10983354Abstract: A multiplanar head mounted display (HMD) includes two or more artificial display planes for each eye located at optical distances that can be dynamically adjusted based on a location within a scene presented by the HMD that the user views. For example, a scene is presented on two or more electronic display elements (e.g., screens) of the HMD. A focal length of an optics block that directs image light from the electronic display elements towards the eyes of a user is adjusted using a varifocal system (e.g., an element that mechanically changes a distance between a lens system in the optics block and the electronic display element, an element that changes shape of one or more lenses in the lens system in the optics block, etc.) based on a location or object within the scene where the user is looking.Type: GrantFiled: January 7, 2020Date of Patent: April 20, 2021Assignee: Facebook Technologies, LLCInventors: Douglas Robert Lanman, William Aaron Nicholls, Marina Zannoli, Kevin James MacKenzie, James Hillis, Yusufu Njoni Bamaxam Sulai, Olivier Mercier

Patent number: 10694166Abstract: Systems and methods for displaying an image across a plurality of displays are described herein. Pixel intensity values in the multifocal display are determined using correlation values and numerical iterations. An eye tracking system measures eye tracking information about a position of a user's eye, and the pixel intensity values are modified based on the eye tracking information. An image is displayed on the plurality of displays based on the determined pixel intensity values. The plurality of displays may be within an HMD, and address vergence accommodation conflict by simulating retinal defocus blur.Type: GrantFiled: January 2, 2020Date of Patent: June 23, 2020Assignee: Facebook Technologies, LLCInventors: Olivier Mercier, Yusufu Njoni Bamaxam Sulai, Kevin James MacKenzie, Marina Zannoli, James Hillis, Derek Nowrouzezahrai, Douglas Robert Lanman

Patent number: 10656707Abstract: A head mounted display (HMD) includes an eye sensor, an optics block, and a display. The eye sensor includes a detector and a tunable lens. The tunable lens has a micro-lens state (e.g., acts as a micro-lens array) and a neutral state. In the micro-lens state the eye sensor acts as an accommodation sensor, and in the neutral state the eye sensor acts as an eye tracking sensor. The eye sensor can alternate functioning as an eye tracking or an accommodation sensor by adjusting the state of the tunable lens. In alternate embodiments, the accommodation sensor is separate from the eye tracker and a beam splitter is used to split the reflected light toward the two sensors.Type: GrantFiled: April 10, 2018Date of Patent: May 19, 2020Assignee: Facebook Technologies, LLCInventors: Robin Sharma, Marina Zannoli, Kevin James MacKenzie
