Abstract: A head-mounted device may include optical assemblies for presenting images to a user. Motors may be used to adjust the spacing between the optical assemblies to accommodate different interpupillary distances. Gaze trackers may be used to make interpupillary distance measurements and eye relief measurements. Adjustments to the positions of the optical assemblies may be made by the motors based on the interpupillary distance measurements and eye relief measurements.

Abstract: A head-mounted display may display images in eye boxes. Right and left gaze tracking sensors may gather left eye gaze information from a left eye box and right eye gaze information from a right eye box. During operation in a first mode in which the right and left gaze tracking sensors are not impaired, gaze information from the right and left gaze tracking sensors may be used in presenting foveated and distortion-corrected image content on the displays and/or in otherwise operating the left and right displays. During operation in a second mode in which one of the gaze tracking sensors is impaired, gaze information for the impaired sensor may be estimated from gaze information for the unimpaired sensor in combination with an object depth estimate based on depth buffer information, vestibulo-ocular-reflex gain information, and historical information.

Abstract: Various implementations disclosed herein include devices, systems, and methods that present content items (e.g., movies, TV shows, home-made videos, etc.) on electronic devices such as HMDs. Some implementations adjust what is being displayed by the electronic devices to mitigate optical module-based artifacts (e.g., ghosting). For example, in an HMD with a catadioptric lens, a mirror layer may leak some light to produce ghosting artifacts that may be mitigated by adjusting brightness, dynamic range, contrast, light-spill, color, etc. Some implementations utilize adjustments that are based on content item awareness (e.g., adjustments based on the peak brightness of the scene in a movie that is being displayed within an extended reality (XR) environment, etc.). Some implementations provide adjustments based on environment awareness (e.g., how dark is the surroundings or pass-through environment) and/or optical module modeling. The adjustments may change a particular content item and/or an environment in which it is presented.

Abstract: One exemplary implementation involves performing operations at an electronic device with one or more processors and a computer-readable storage medium. The device establishes a wireless communication link with a host device. The device receives, from the host device, a left eye frame and a right eye frame via a sequence of left eye frame transmissions and right eye frame transmissions. The device switches data transmissions schemes according to wireless commination link quality or eye gaze tracking. Adjusting transmission format based on transmission quality of the wireless communication link allows the devices to take advantage of greater bandwidth when available to save power. An additional transmission format is based on alternately transmitting left eye and right eye frames for very low bandwidth.

Abstract: A head-mounted display may include a display system and an optical system in a housing. The display system may have displays that produce images. Positioners may be used to move the displays relative to the eye positions of a user's eyes. An adjustable optical system may include tunable lenses such as tunable cylindrical liquid crystal lenses. The displays may be viewed through the lenses when the user's eyes are at the eye positions. A sensor may be incorporated into the head-mounted display to measure refractive errors in the user's eyes. The sensor may include waveguides and volume holograms, and a camera for gathering light that has reflected from the retinas of the user's eyes. Viewing comfort may be enhanced by adjusting display positions relative to the eye positions and/or by adjusting lens settings based on the content being presented on the display and/or measured refractive errors.

Abstract: An electronic device such as a head mounted device may have a display that displays an image for a user. Head-mounted support structures may be used to support the display and to support lenses. The image on the display is visible through the lenses from eye boxes. The presence of the user's nose and the presence of opaque lens holder structures presents a risk that some of the image will be obscured by undesired black regions. To reduce or eliminate these black regions, facial illumination may be generated using a light source in the electronic device. The facial illumination may be provided by a light source such as a light-emitting diode die or laser or may be provided by a corner region of the display that contains pixels that do not supply any part of the image.

Abstract: A head-mounted device may have optical modules that present images to a user's left and right eyes. Each optical module may have a lens support structure that supports a display and a fixed lens. Vision correction lenses may be removably coupled to the fixed lenses to help customize the head-mounted device to the vision of a particular user. A user may view images on the displays through the removable and fixed lenses from eye boxes. The optical modules may include infrared light sources that supply infrared light to the eye boxes and infrared light sensors such as infrared cameras for gaze tracking and authentication. The lenses may have optical surfaces covered with coating that enhance optical performance and may have edge surfaces that are provided with structures to help reduce stray light reflections. The lenses may be configured to pass visible and infrared light.

Abstract: An electronic device such as a head-mounted device may have a display that is viewable by a user from eye boxes. The electronic device may have a gaze tracking system that monitors a user's eyes in the eye boxes to gather gaze direction information. The display may have a central portion and a peripheral portion. The peripheral portion may have a lower resolution than the central portion and may be used in displaying content that is viewable in a user's peripheral vision. During operation, control circuitry in the electronic device may adjust peripheral content on the peripheral portion to correct for parallax-induced mismatch between the peripheral content and central content on the central portion of the display. The control circuitry may also depower peripheral pixels that are determined to be unviewable based on the gaze direction. Diffusers may be used to hide seams between the central and peripheral display portions.
