Aspects of the present disclosure are directed to providing an artificial reality environment with augments and surfaces. An “augment” is a virtual container in 3D space that can include presentation data, context, and logic.

Aspects of the present disclosure are directed to a dynamic boundary that triggers operating changes at an artificial reality system. Implementations of a dynamic boundary manager can enforce dynamic boundary criteria. A dynamic boundary that corresponds to the user can be automatically generated, such as when the artificial reality system operates in a certain operating condition. User movements can trigger dynamic boundary criteria and cause one or more of: expansion of the dynamic boundary; popping of the dynamic boundary; and/or reforming of the dynamic boundary. Responsive to these triggers, the dynamic boundary manager can also cause changes to operations at the artificial reality system, such as pause(s) to executing applications and/or changes to the artificial reality environment displayed to the user (e.g., transitions to and from a virtual reality environment, a pass-through visual, etc.).
Aspects of the present disclosure are directed to operating an artificial reality system in single-handed mode. Artificial reality systems receive user input via several channels, however conventional systems lack functionality that helps diverse users operate these systems. Some types of input, such as input that requires movement of two hands and/or two hand-held controllers, may be more challenging for some diverse individuals to provide or may not be possible in certain situations, e.g., where one controller is disabled. Implementations operate artificial reality systems in single-handed mode, such as by translating instances of single-handed input into two-handed input. For example, the translated two-handed input can cause application functionality at the artificial reality system that would otherwise pose a challenge for some diverse individual.

Generating Targetable Remote Haptic Sensations using Through Body Mechanical Waves
A device worn on the human body can stimulate targeted mechanoreceptors from a distance beyond their receptive fields through use of modulated mechanical waves transmitted from an array of transducers which generate one or more specific subsurface strains at the target mechanoreceptors.
A capacitive sensor for use in a wearable or flexible input device is described. The capacitive sensor includes a dielectric knitted core comprising deformable polymer patches deposited on a top surface of the dielectric knitted core, conductive electrode layers with stretchable electrodes positioned on the top and bottom surfaces of the dielectric knitted core, and a conductive textile shielding layer on each of the conductive electrode layers. The deformable polymer patches stiffen regions of the dielectric knitted core corresponding to the stretchable electrodes to limit strain on the stretchable electrodes as a wearer of the input device moves and deforms the input device during use. Moreover, the conductive electrode layers and conductive textile shielding layers comprise openings around the stretchable electrodes that redistribute strain away from the stretchable electrodes. These features limit motion artifacts while maintaining the flexibility and comfortability of the input device.
An example, facial interface structure for an extended-reality headset comprises a front portion configured to couple with a head-facing portion of an extended-reality headset, and a rear portion configured to couple with a portion of the user's face, wherein the front portion is configured to move relative to the rear portion in response to a force applied by a strap around a head of a user. The example facial interface includes two side support structures coupling the front portion to the rear portion, where each of the side support structures is configured to be positioned on a different respective side of the user's face. In addition, movement of the front portion relative to the rear portion causes, via the two side support structures, the rear portion to deform to thereby conform the rear portion to a profile of a user's head.
A head-wearable device comprising one or more displays and one or more programs. The one or more programs include instructions for, in response to a detection of an object within a field-of-view of the user, presenting a first XR augment overlaid over a first portion of the field-of-view of the user that is associated with the object. The one or more programs further include instructions for, in accordance with a determination that a first user eye movement is focused on the first XR augment for a first predetermined time, replacing the first XR augment with a second XR augment. The one or more programs further include instructions for, in accordance with a determination that a second user eye movement is focused outside a perimeter of the second XR augment for a second predetermined time, replacing the second XR augment with a third XR element.
The present disclosure regards devices, methods, and systems for dynamically enhancing visual XR content. An example device is an XR device with a display device, a lens, and one or more programs. The programs of the XR device include instructions for determining a hardware pixels-per-degree (“HPPD”) metric for the XR device and for determining a render pixels-per-degree (“RPPD”) metric for visual XR content to be displayed by the XR device. The programs further include instructions for determining whether a difference between the HPPD metric and the RPPD metric satisfy a minimum difference threshold and, after determining that the threshold is satisfied, enhancing the visual XR content based on the difference between the metrics. For example, if the HPPD metric is greater than the RPPD metric, then enhancement may involve applying a sharpening filter to the visual XR content; otherwise, it may involve super-sampling the content.

A method of providing remote haptic feedback is described. The method includes applying, via a set of electrodes of a wearable device, a haptic signal to a first portion of a user. The haptic signal is configured to cause haptic feedback to be perceived at a second portion of the user that is distinct from the first portion of the user.

An optical element may include two or more zones to perform functions in a head-mounted display (HMD) device. An optical component may include a first optical zone characterized by a first sag profile to correct a refractive error of an eye of a user and a second optical zone characterized by a second sag profile to redirect a path of an illumination light beam. A transition zone located between the first optical zone and the second optical zone may provide a smooth transition between the first optical zone and the second optical zone.
The present disclosure is generally directed to techniques for editing a portion of a 3D scene represented by a neural field model. Examples of the present disclosure may erase an object from a 3D scene by identifying the object in one or more images of the scene and generating mask regions around (e.g., covering) the object in these images. A neural field model that represents the scene without the object in it may be trained by relying on an image generative model configured for inpainting. When trained, this 'background' neural field model can be used to render the implicit background of light rays that pass through the region of 3D space represented by the mask regions, thereby producing different views of the scene with the object effectively erased from the scene.
