Abstract: Embodiments are directed to a near eye display (NED) system for displaying artificial reality content to a user and to manipulate displayed content items based upon gestures performed by users of the NED system. A user of the NED system may perform a gesture simulating the throwing of an object to “cast” a content item to a target location in an artificial reality (AR) environment displayed by the NED system. The gesture may comprise a first portion in which the user's hand “grabs” or “pinches” a virtual object corresponding to the content item and moves backwards relative to their body, and a second portion in which the user's hand moves forwards relative to their body and releases the virtual object. The target location may be identified based upon a trajectory associated with the backwards motion of the first portion of the gesture.

Abstract: In one embodiment, a method includes receiving a plurality of uniform resource identifiers (URI's) associated with a particular domain. Each of the URI's identifies a content page comprising one or more signature elements. The method further includes, for each URI in the plurality of URI's, successively testing the URI to identify a core of the URI and any unnecessary elements of the URI. The core of the URI is sufficient to retrieve a version of the content page including all of its signature elements. The method additionally includes, for each URI in the plurality of URI's, updating a set of rules based on the identified core and the identified unnecessary elements. The set of rules establishes a normalized version of the URI.

Abstract: A user may make a digital item available to other users of a computer network, such as an instant messaging system, a chat environment, or a subscription-based computer network. Examples of digital items that may be shared with other users include digital representations of graphic images, photographs, audio segments, songs, video segments, movies, and text (such as lists of favorites (e.g., a list of favorite books, a list of favorite movies, and a list of favorite places to visit)). On-line presence information is provided to indicate the on-line presence of users with whom a digital item has been shared, may be shared or is being shared. For instance, an indication of the on-line or offline status of a user with whom an item has been shared or is being shared may be presented.

Abstract: Artificial reality (AR) systems track pose and skeletal positioning for multiple co-located participants, each having a head mounted display (HMD). Participants can join a shared artificial reality event or experience with others in the same location. Each participant's HMD can independently render AR content for the participant based on the participant's pose and pose information obtained from other participants' HMDs. A participating HMD may broadcast tracking estimates for skeletal points of interest (e.g., joints, finger tips, knees, ankle points, etc.) that are within the field-of-view of the HMD's cameras and/or sensors. A participating HMD may receive skeletal position information determined by other HMDs, and aggregate the received tracking information along with internal tracking information to construct an accurate, full estimate of its own pose and skeletal positioning information for its corresponding participant.

The transition region of the knitted layer may progressively change in degree of the at least one physical property proceeding from the first region toward the second region. Various other apparatuses, systems, and methods are also disclosed.

Abstract: A near-eye display (NED) using a pupil expander to expand an eyebox of the NED may suffer from local variations of throughput and color reproduction introduced by the pupil expander of the display. To offset or compensate these variations, the pupil expander, e.g. a pupil-replicating waveguide, may be characterized at a plurality of non-uniformly spaced grid of test points, with the test points disposed more densely at areas of high spatial variation of the throughput or color shift introduced by the pupil expander. The throughput or color shift may be integrated over at least a portion of the field of view of the NED. To determine the areas of high spatial variation, an initial test may be performed at uniformly spaced test grid locations.

Abstract: Systems, methods, and non-transitory computer-readable media can determine that a team within an organization has an available job position. A job posting for the available job position is generated, wherein the job posting comprises job information that has been automatically determined.

Abstract: Systems and methods are disclosed herein for receiving, by a social networking system, from a domain, a request to publish a content item. The social networking system publishes the content item and receives a request to reshare the content item from a user. The social networking system responsively determines a reputability score for the domain based on a number of other domains that point to the domain in the context of the social network interface, and determines whether the reputability score exceeds a threshold score. If the reputability score exceeds the threshold, the social networking system publishes the content item using a default ranking. Otherwise, the content item is published using a discounted ranking derived from taking a discount from the default ranking such that the content item is ranked lower relative to other content items than it would have been if the default ranking had been used.

Abstract: In one embodiment, a method includes establishing a video call between multiple client systems and determining user identifiers of users associated with the video call. Whether to provide content recommendations during the video call may then be determined based on a current context of that video call, and one or more content items to recommend may be selected based on the determined user identifiers. Finally, in response to determining to provide content recommendations during the video call, a first content recommendation with the selected content items may be sent to one or more of the client systems while maintaining the video call between those client systems.

Abstract: In one embodiment, a computing system may be configured to generate accurate and realistic computer-generated clothing for a given body pose. For example, the system may access a data representation of a body pose and generate, based on the data representation, a 3D clothing model for the body pose using a statistical model. The system may generate a first normal map, such as a low-resolution normal map, based on the 3D clothing model. The system may generate a second normal map, such as a high-resolution normal map, by processing the first normal map using a machine-learning model that is trained to generate normal maps with higher levels of detail from normal maps with relatively lower levels of detail. The system may then render clothing for the body pose based on the 3D clothing model and the second normal map.

Abstract: A first group of modulo result matrices corresponding to modulo of elements of a first matrix by each of a plurality of moduli is stored. A second group of modulo result matrices corresponding to modulo of elements of a second matrix by each of the plurality of moduli is stored. It is determined whether an element operation of a multiplication of the first matrix with the second matrix can be performed using a first hardware multiplication module rather than a second hardware multiplication module. In response to a determination that the element operation can be performed using the first hardware multiplication module, the element operation is performed using the first hardware multiplication module including by multiplying one or more corresponding elements from the first group of modulo result matrices with one or more corresponding elements from the second group of modulo result matrices.

Abstract: Techniques are described that update a caller on call progress status using various effects based on a likelihood that the call will connect with the callee, and/or a likelihood that the caller will prematurely terminate the call. In some examples, a machine-learned model may determine a likelihood that a call will connect based on conditions associated with the callee. In some cases, a machine-learned model may determine a likelihood that a call will be prematurely terminated by the caller based on conditions associated with the caller. Animations, haptic outputs, sounds, and/or other content may be used to indicate likelihood of the call connecting to the caller.

Abstract: A load balancer allocates requests to a pool of web servers configured to have low queue capacities. If the queue capacity of a web server is reached, the web server responds to an additional request with a rejection notification to the load balancer, which enables the load balancer to quickly send the rejected request to another web server. Each web server self-monitors its rejection rate. If the rejection rate exceeds a threshold, the number of processes concurrently running on the web server is increased. If the rejection rate falls below a threshold, the number of processes concurrently running on the web server is decreased.

Abstract: Systems, methods, and non-transitory computer-readable media can determine that at least one image has been captured using the computing device, wherein one or more individuals are represented in the image. An identity of at least a first individual of the one or more individuals represented in the image is determined, wherein the identity of the first individual is determined, at least in part, using a social networking system. A notification is presented through a display of the computing device, wherein the notification provides an option to send a message including the captured image to the first individual.
