Abstract: Techniques disclosed herein relate to a near-eye display system. One example of an optical device of a near-eye display includes a substrate and holographic grating conformally coupled to a surface of the substrate. The substrate is transparent to visible light and infrared light and is configured to be placed in front of an eye of a user of the near-eye display. A refractive index modulation of the holographic grating is apodized in a surface-normal direction of the substrate to reduce optical artifacts in the visible light.

Abstract: Parallel processing of frames by a first and second thread is disclosed. In particular, the systems and methods can process multiple frames in a pipelines manner by a JavaScript thread and a UI thread. The system first executes a first frame by a JavaScript thread during a first time interval. The system then executes the first frame by a UI thread during a second time interval. While the UI thread is executing the first frame, the JavaScript thread executes a second thread in parallel during the second time internal. As a result, latency is added to UI processing while maintaining the same throughput, to add parallelism. The JavaScript and UI threads can be handled by different processors (e.g., using a multi-core processor), thereby adding further parallelism and increasing the efficiency of processing an event.

Abstract: In one embodiment, a computing system may determine a first orientation of a viewer in a three-dimensional (3D) space based on first sensor data associated with a first time. The system may render one or more first lines of pixels based on the first orientation of the viewer and display the one or more first lines. The system may determine a second orientation of the viewer in the 3D space based on second sensor data associated with a second time that is subsequent to the first time. The system may render one or more second lines of pixels based on the second orientation of the viewer and display the one or more second lines of pixels. The one or more second lines of pixels associated with the second orientation are displayed concurrently with the one or more first lines of pixels associated with the first orientation.

Abstract: A method for executing commands includes a wearable device with an inflatable bladder and a sensor integrated with the inflatable bladder. The method includes transitioning the inflatable bladder from an unpressurized state to a pressurized state. The inflatable bladder is associated with an executable command when in the pressurized state. The method further includes detecting, by the sensor, the magnitude of depression of the inflatable bladder and determining whether the magnitude of depression satisfies a predetermined threshold. When the magnitude of depression satisfies the predetermined threshold, the method executes the executable command.

Abstract: Techniques are described that allow a user to control and/or restrict dissemination of content by other users related to an account of the user. For example, a request may be received, from a first user account, to restrict presentation of content having a characteristic and received from a second user account. An item of content having the characteristic may be received from the second user account. A first instruction to present a first representation of the item of content is sent to a first computing device associated with the first user account and based at least in part on the request to restrict presentation. A second instruction to present a second representation of the item of content is sent to a second computing device associated with the second user account, the second representation of the item of content being different than the first representation of the item of content.

Abstract: The present disclosure is directed toward systems and methods for optimizing view-through conversion rates. For example, systems and methods described herein train and utilize a machine learning model that predicts whether providing a digital impression to a particular networking system user will result in a conversion. Systems and methods described herein identify view-through conversions by generating a vector associated with the provision of a digital impression to a networking system user and receiving third-party conversion information during an attribution window. The systems and methods described herein then utilize the vector and conversion information to train the machine learning model to predict future conversions.

Abstract: Exemplary embodiments relate to techniques for sharing live video while maintaining an asynchronous copy of the video. According to some embodiments, a user begins to record video and shares the video with selected other users. If one of the other users opts to join the original user, the shared video upgrades to a live video conversation. If no one (or only some participants) joins the original user, the recorded video becomes an asynchronous artifact in the users' messaging history. In some embodiments, the live video may be recorded and shared in response to a first user initiating a video call with at least a second user, but receiving no answer. The first user begins to share a live video (which may become an asynchronous artifact). If the second user joins the call while the video is being recorded, the conversation may upgraded to a video conversation.

Abstract: A head-mounted display device for providing augmented reality contents to a wearer includes a light projector and a pancake combiner. The light projector is configured to project a light having a first polarization for rendering images based at least on the augmented reality contents. The pancake combiner is configured to combine the light from the light projector and light from an outside of the head-mounted display device for providing an overlap of the rendered image and a real image that corresponds to the light from the outside of the head-mounted display device. The pancake combiner is also configured to direct the light from the light projector toward a pupil of an eye the wearer.
