Abstract: systems and methods of calibrating a head-wearable device are disclosed. an example method includes, while a position of an artificial-reality glasses relative to a storage device satisfies position criteria, causing the artificial-reality glasses to display calibration patterns using a lens assemblies of the artificial-reality glasses, and capturing, using an imaging device communicatively coupled to the storage device and associated with the lens assemblies, calibration images of the calibration patterns displayed using the lens assemblies of the artificial-reality glasses. the method further includes, in accordance with a determination, based on the calibration images, that an amount of disparity between the respective calibration patterns displayed using the lens assemblies satisfies calibration criteria, causing the artificial-reality glasses to apply, based on the amount of disparity, a disparity correction to one or more of the lens assemblies.
Abstract: a pair of artificial-reality glasses that comprise a deformable frame, a rigid unibody member (distinct from the deformable frame and configured to couple to the deformable frame), a first lens assembly (coupled to a first portion of the rigid unibody member) and a second lens assembly (coupled to a second portion of the rigid unibody member at a predefined relative position to the first lens assembly), depth sensors, force sensors, and processors. a nose bridge portion of the rigid unibody member includes structure reinforcements. the force sensors detect deformation of the rigid unibody member such that the second lens assembly is not at the predefined position relative to the first lens assembly. the processors receive deformation data from the one or more force sensors and cause the artificial-reality glasses to apply a disparity correction to the first lens assembly and the second lens assembly.

20250199604. MIXED REALITY INTERACTION EYE-TRACKING TECHNIQUES (Meta Platforms Technologies, LLC)
Abstract: mixed reality (mr) user interactions are enabled through a combination of eye tracking (user gaze determination) and secondary inputs such as finger gestures, hand gestures, eye gestures, wrist band device input, handheld controller input, and the like. a location of interest (loi) may be identified in displayed content and/or the external environment through the user's gaze, fixation, and/or saccades, and then other actions, such as zoom, rotate, pan, move, open actionable menus, etc., may be performed on the loi based on the secondary inputs.

20250199611. Look Pin Artificial Reality Device (Meta Platforms Technologies, LLC)
Abstract: when a notification is to be shown, an artificial reality notification system can add the notification to a pre-defined location in the user's field of view (e.g., top, side, or bottom) where it stays as a head leashed virtual object until the user's gaze is direct to the notification. when the user's gaze is directed at the notification, the artificial reality notification system can make the notification world locked, allowing the user to move her head to bring the notification to the center of her field of view, move closer to the notification to make it larger, move around the notification to see aspects from different angles, etc. the notification can be dismissed if the user never directs her gaze at it for a first threshold amount of time or when the user looks away from the world-locked version for a second threshold amount of time.
Abstract: techniques disclosed herein relate generally to modifying images to reduce display power while maintaining visual fidelity of the displayed images. in one example, a computer-implemented method includes receiving an input image to be displayed by a type of display device, obtaining a machine learning model that is trained to edit display content to reduce power consumption of displaying the edited display content by the type of display device while maintaining a visual fidelity of the edited display content, applying the machine learning model to the input image to generate an output image, and displaying the output image via a display device of the type of display device.
20250199758. Automatic Quantitative Food Intake Tracking (Meta Platforms Technologies, LLC)
Abstract: aspects of the present disclosure are directed to quantitatively tracking food intake using smart glasses and/or other wearable devices. in some implementations, the smart glasses can include an image capture device, such as a camera, that can seamlessly capture images of food being eaten by the user. a computing device in communication with the smart glasses (or the smart glasses themselves) can identify the type and volume of food being eaten by applying object recognition and volume estimation techniques to the images. additionally or alternatively, the smart glasses and/or other wearable devices can track a user's eating patterns through the number of bites taken throughout the day by capturing and analyzing hand-to-mouth motions and chewing. the computing device can log the type of food, volume of food, and/or number of bites taken and compute statistics that can be displayed to the user on the smart glasses.
20250200893. CONTEXTUAL TIME-BASED DIGITAL REPRESENTATIONS (Meta Platforms Technologies, LLC)
Abstract: various aspects of the subject technology relate to systems, methods, and machine-readable media for generating time-based interactive digital representations of a subject. various aspects may include receiving a request for generating the interactive digital representations, wherein the request specifies the subject. aspects may also include determining a time period covering a time span associated with the request. aspects may also include retrieving contextual information associated with the subject and restricted by the time period. aspects may also include generating, based on the contextual information, a model representing a persona of the subject in the time period. aspects may include outputting an interactive digital representation of the model in a user interface (e.g., a conversational agent in a messaging application or avatar in a virtual environment), enabling user interactions with the model.
Abstract: aspects of the present disclosure relate to automatic repositioning of virtual objects, in an augmented or mixed reality environment, to avoid occlusion of certain physical objects or views in the real-world environment. conventionally, on a head-worn artificial reality system, head-leashed virtual objects simply follow where the head is pointed. some implementations can detect regions in the field-of-view of the user that should not be occluded, such as faces of other people, media content, a particular activity being performed, and/or where the user's gaze has lingered, and reposition virtual objects to avoid these areas. alternatively or additionally, some implementations can detect movement of the user in the real-world environment and trigger minimization, repositioning, and/or degradation of virtual objects to lessen obstructions in the user's viewpoint and conserve resources. after the user slows or stops moving, the virtual object can revert to its full form.
20250203005. Controlling Augmented Call Based User Gaze (Meta Platforms Technologies, LLC)
Abstract: aspects of the present disclosure are directed to controlling a sending side of an augmented call based on a receiving user's gaze. some implementations provide a hologram moderation system in which a receiving user's gaze can control how the system generates a representation of a sending user on a sending side. for example, some implementations can moderate the capture or generation of hologram data representing the sending user when the receiving user isn't focused on the hologram that results from the data. such moderations can reduce power consumption, bandwidth, heat production, and/or processing power needed by the artificial reality system when the receiving user is not looking at the hologram of the sending user, such as when the sending user is in the receiving user's periphery or outside the receiving user's field-of-view.
20250203728. Light Emitting Diode Control Circuitry (Meta Platforms Technologies, LLC)
Abstract: aspects of the present disclosure are directed to systems and methods for controlling light emitting diodes (leds) in an electronic device, such as an artificial reality (xr) head-mounted display (hmd) or other xr device in an xr system. in an xr hmd, the leds can be positioned proximate to and/or facing the eyes and/or face of a user to illuminate such features for movement tracking and other purposes. implementations can provide led control circuitry that can continuously monitor the output current provided to the leds. if the integral of the output current over time exceeds a threshold current, implementations can latch the current to the leds.
