Abstract: Systems, methods, and non-transitory computer readable mediums including processes to correct for distortion in images introduced by eyewear (i.e., where the facial region surrounding the eye has a boundary that doesn't match the boundary of an uncovered facial region). The correction includes segmenting images to detect eyewear covered facial regions and facial regions not covered by the eyewear and altering the covered facial regions to match the covered facial boundary to the uncovered facial boundary. Alterations include processing using a machine learning model, applying anti-refraction algorithms, scaling the covered facial region to match boundaries of the uncovered facial region, or a combination thereof.

The support structure defines a region for receiving at least a portion of a head of a user. The eyewear also includes a biometric sensor coupled to the electronic components and supported by the support structure. The biometric sensor is attached to the support structure and positioned to detect, in the region, a biometric signal representative of a biometric of the user for processing by the electronic components.

Abstract: A server machine modifies an augmented reality (AR) object in response to fulfillment of a condition. The machine provides, to a user device, object data that defines the AR object. The object data specifies a physical geolocation of the AR object, a presentation attribute of the AR object, a conditional modification program, and a trigger condition for execution of the conditional modification program. The object data causes the user device to present the AR object with a first appearance, located at the physical geolocation. The machine detects fulfillment of the trigger condition, and in response, the machine executes the conditional modification program. This modifies the object data by modifying the presentation attribute. The machine provides, to the user device, the modified object data, which causes the user device to present the AR object with a second appearance based on the modified presentation attribute.

Abstract: Method for generating haptic feedback responses starts with processor causing communication interface for communication session to be displayed on first user interface and on a second user interface. Processor detects first touch input on first user interface and second touch input on second user interface. Processor monitors location of the first touch input on the first user interface and location of the second touch input on the second user interface. Processor determines distance between location of first touch input on first user interface and location on first user interface corresponding to location of second touch input on second user interface. Processor causes the first user interface and the second user interface to generate a haptic feedback response based on the distance. The haptic feedback response increases in intensity or speed as the distance decreases and decreases in intensity or speed as the distance increases. Other embodiments are described herein.
