Abstract: Exemplary embodiments relate to techniques for notifying existing users when a new user joins a messaging service (or returns from a period of inactivity). A top n number of existing users acquainted with the new user may be selected and may be encouraged to message the new user. The existing users may be selected using a messaging coefficient that indicates a likelihood that a message will result in a meaningful conversation, and a number of other factors that prevent the existing users from becoming inundated with notifications. The number n may be selected based on an amount of display space available to the new user in a messaging application. When inviting the existing users to contact the new user, a new thread may be automatically created and bumped to the top of the new user's thread list.

Abstract: The disclosed computer-implemented method may include tracking, using a low-order degree-of-freedom (DOF) mode, an orientation of a device based on input from an inertial measurement unit (IMU) of the device. The method may also include determining, using a magnetometer, that the device has entered a magnetic tracking volume defined by at least one magnet and in response to determining that the device has entered the magnetic tracking volume, transitioning from the low-order DOF mode to a high-order DOF mode that tracks a higher number of DOFs than the low-order DOF mode. The method may also include tracking, using the high-order DOF mode, the position and orientation of the device based on input from both the IMU and the magnetometer. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: The present disclosure describes techniques for enabling users (such as users of a social networking system) to access media effects associated with events. The users may then use the media effects to create media content. For example, a user-selectable option may be provided to a device of a user such that selection of the user-selectable option causes one or more media effects associated with an event to be output by the device. In certain embodiments, techniques are described for selectively providing media effects associated with events to selected users. The selected users may then use the media effects to create media content. For example, a media effect may be associated with one or more conditions for providing the media effect to a user. Only users that satisfy the one or more conditions may get access to the media effect.

Abstract: A social networking system identifies a user's relative preference for objects maintained by the social networking system, such as pages associated with movies, restaurants, businesses, or other content. To obtain the user's preferences, the system provides pairs, or groups, of objects to a user and prompts the user to indicate a preference between the objects in each pair. This obtained information about the user's relative preferences is stored in conjunction with the user's profile, which can then be used to select content subsequently presented to the user.

The thin-film layer is configured to be removably attached to a substrate, such that a molecular pattern for the at least one predetermined optical function of the thin-film layer is preserved post removal.

Abstract: An optical element for a head mounted display (HMD) includes an illumination layer, an optical combiner, and an optically transparent layer. The illumination layer is configured to emit infrared light towards an eyeward side of the optical element. The optical combiner is configured to receive reflected infrared light that is reflected by an eye of a user and to direct the reflected infrared light towards an infrared camera. The optically transparent layer is disposed between the illumination layer and the eyeward side of the optical element. The optical element may further include one or both of a confinement layer and an infrared extractor. The confinement layer is disposed on a surface of the optically transparent layer to induce waveguiding of confined infrared light propagating within the optically transparent layer. The infrared extractor is disposed on a side-edge of the optically transparent layer to absorb or frustrate the confined infrared light.

Abstract: A user interacts with a virtual digital assistant with the intent that it provides assistance with a task. The user sends messages to the virtual digital assistant that include content obtained via user input at a client device. An intent determination model is applied to the content to identify the user's intent. The virtual digital assistant identifies agents that are capable of servicing the intent are identified and retrieves contextual data relating to the message from a data store. An intent arbitration model is used to select one of the agents which is activated to provide assistance with the task. The contextual information may include global metrics of agent performance and/or information regarding the user's preferences.

Abstract: This disclosure covers methods, non-transitory computer readable media, and systems that receive a direct digital message for delivery to a recipient and then generate a relevance score representing the direct digital message's relevance to the recipient. The relevance score accounts for either or both of crowdsourced information and social-network signals. Based on the relevance score, the methods, non-transitory computer readable media, and systems either provide the direct digital message to the recipient's client device for display within a received-messages preview or provide the message to the recipient's client device for sequestration within a sequestration folder.
