    Abstract: Systems and methods for varying an intensity of pixels of displays are provided. A display subsystem may include a display driver for receiving image frame data and commands from an image or data source, including pixel intensity values for bit planes of an image frame; a parser for receiving the image frame data and the commands, and configured to determine a drive waveform having an pixel drive value and a pixel drive time interval for each bit plane of the image frame data; a display backplane for receiving the drive waveform, the display backplane including a pixel array comprising an array of pixels, each pixel driven by a pixel circuit; and display driver circuitry for driving the pixels in accordance with the drive waveform; and wherein an intensity of the pixel varies for each bit plane according to the pixel drive value and the pixel drive time interval.

    Abstract: The subject technology captures first image data by a computing device, the first image data comprising a target face of a target actor and facial expressions of the target actor, the facial expressions including lip movements. The subject technology generates, based at least in part on frames of a source media content, sets of source pose parameters. The subject technology receives a selection of a particular facial expression from a set of facial expressions. The subject technology generates, based at least in part on sets of source pose parameters and the selection of the particular facial expression, an output media content. The subject technology provides augmented reality content based at least in part on the output media content for display on the computing device.

    Abstract: An augmented reality (AR) eyewear device has a lens system which includes an optical screening mechanism that enables switching the lens system between a conventional see-through state and an opaque state in which the lens system screens or functionally blocks out the wearer's view of the external environment. Such a screening mechanism allows for expanded use cases of the AR glasses compared to conventional devices, e.g.: as a sleep mask; to view displayed content like movies or sports events against a visually non-distracting background instead of against the external environment; and/or to enable VR functionality.

    Abstract: The technical problem of matching records in different datasets, for example a host dataset and a partner dataset storing records representing respective users, while maintaining the privacy of each dataset, is addressed by providing a privacy safe joint identification protocol. The privacy safe joint identification protocol computes respective anonymous joint identifiers for records in the two datasets. An anonymous joint identifier is generated such that the host-assigned and the partner-assigned identifies that have been determined to represent the same user are mapped to the same anonymous joint identifier.

    Abstract: Aspects of the present disclosure involve a system comprising a computer-readable storage medium storing a program and method for providing a room preview within a virtual conferencing system. The program and method provide for virtual conferencing between plural participants within a first room of plural rooms, the plural rooms being included within a virtual space for virtual conferencing; and for each of the plural participants, provide a first audio channel associated with audio output of the first room, provide display of a room preview element within the first room, the room preview element corresponding to a live preview of a second room of the plural rooms, and provide a second audio channel associated with audio output of the second room.
