Abstract: A near-eye display (NED) includes an image replicator and an image combiner. The image replicator is configured for receiving a beam of image light from a source such as an image projector, and splitting the beam into a plurality of second beams of image light. The combiner is configured to relay the plurality of second beams to an eyebox of the NED such that the second beams at the eyebox are laterally offset from one another. The etendue of the NED may be increased by replicating and relaying the image beams.

Abstract: In one embodiment, a feature map of an image having h×w pixels and a patch having one or more pixels of the image are received. The patch has been processed by a first set of layers of a convolutional neural network and contains an object centered within the patch. The patch is then processed using the feature map and one or more pixel classifiers of a classification layer of a deep-learning model, where the classification layer includes h×w pixel classifiers, with each pixel classifier corresponding to a respective pixel of the patch. Each of the pixel classifiers used to process the patch outputs a respective value indicating whether the corresponding pixel belongs to the object centered in the patch.

Abstract: In one embodiment, a method includes a computing system generating a forum for a discussion regarding a television program among a plurality of users watching the television program. The television program may be aired on a plurality of first devices. The system may provide, on a plurality of second devices of the users watching the television program, a user interface comprising the forum and one or more affinity indicators for expressing user emotions relating to the television program. The system may receive, from a second device of a user, user input indicating a comment or a user emotion relating to the television program through the one or more affinity indicators. The system may distribute in real-time the comment or the user emotion relating to the television program received from the second device of the user across other second devices of the users watching the television program.

Abstract: Exemplary embodiments relate to techniques for representing conversations in a messaging system, where content serves as the organizing feature or primitive of a messaging inbox. In the messaging inbox, content may be aggregated in two hierarchical tiers: first, on a per-sender basis, and second on a per-content basis. Conversational threads may be stored in buckets represented by a relationship tuple (sender, receiver). Individual content threads may be represented by a thread identifier of the structure (content ID, sender, receiver). One piece of content may be associated with multiple conversations through the thread ID. Replies may be organized in a hierarchy under the thread ID tuple. Content ephemerality may be implemented by tying the content identifier to ephemerality conditions. Different users may view the content at different times, since the thread ID tuple can be removed from a sender bucket without removing the associated content.

The nanovoided polymer element may be located at least in part between the first electrode and the second electrode. The planarization layer may be located between the nanovoided polymer element and the first electrode.

Abstract: A driver for powering a pulsed light source of a scanning projector display is configured to provide a succession of powering electric pulses to the light source. Duration of the powering electric pulses is less than a pixel time interval during which a scanner of the projector display is directing the light beam to form a corresponding pixel of the image to be displayed. The amplitude of the powering electric pulses is proportionally higher, such that the light pulse has a pulse energy similar to the light energy provided by the light source when continuously driven through the pixel time interval. This enables the light source to be operated at a steeper portion of the electro-optical transfer curve, thereby improving the wall plug efficiency of the scanning projector display.

Abstract: Folding optics are used in conjunction with a lens system to reduce a back focal length of a head-mounted display. The lens system provides optical power to focus light from an optical display. The folding optics reflects light to fold upon itself to reduce a distance between the lens system and the optical display.

Abstract: In some examples, a virtual surface presented by an artificial reality (AR) system may be a virtual drawing surface in an artificial reality environment, with which users may interact using a physical peripheral device. For example, the AR system may enable a user to draw or write on a surface of the peripheral device and may simultaneously, i.e., along with the user inputs, render virtual markings corresponding to the user inputs on a virtual drawing surface locked to the surface of the peripheral device. In some cases, the AR system enables the user to “transfer” the virtual markings rendered on the surface of the peripheral device (e.g., a virtual drawing) to another virtual drawing surface (e.g., to a planar or other surface in the artificial reality environment).

Abstract: An online system guarantees achievement of an impression goal and a reach goal associated with a set of content items received from a content-providing user of the online system within a period of time associated with the goals. To ensure that the goals are achieved within the period of time, the online system may adjust values of filters associated with the set of content items that control a number of impression opportunities for which the set of content items will be eligible for presentation to users of the online system. The online system may compute a normalized ratio throughout the period of time associated with the goals based on the goals and the progress made by the online system towards achieving the goals. Based on the normalized ratio, the online system may track the performance of the content items and adjust the values of the filters.
