Abstract: An artificial reality system is described that includes a head mounted display (HMD) configured to output artificial reality content and image capture devices configured to capture image data of a peripheral device positioned within a physical environment, where the image data comprises a plurality of successive image frames and the image capture devices capture each image frame during an exposure window of a respective frame period. The artificial reality system further includes a waveform controller configured to program a pulse waveform for a plurality of emitters on a peripheral device, wherein the pulse waveform specifies a pattern by which the plurality of emitters emit light and a pulse emitter synchronizer configured to synchronize the emission of light by the plurality of emitters according to the pulse waveform with the exposure window over the successive image frames from the image capture devices.

Abstract: In one embodiment, a computing system captures, using a camera, a number of frames of a live scene. The system generates preview frames for an augmented scene by applying one or more augmented reality effects to the frames of the live scene. Each preview frame is based on a low-resolution image of the live scene. The low-resolution image has a lower resolution than a maximum resolution of the camera. The system stores at least one preview frame with the augmented reality effects into a storage of the computing device. The system displays a live preview of the augmented scene using the preview frames. The system receives a request from a user to capture an image of the augmented scene while the live preview is being displayed. The system retrieves, the at least one preview frame stored in the storage and outputs the retrieved at least one preview frame.

Abstract: In one embodiment, a method for presenting an augmented reality effect may include receiving, by a computing system, a request for downloading an augmented reality effect, which may include a plurality of elements. The system may select a first subset of elements among the plurality of elements based on one or more predefined rules. The first subset of elements may be transmitted to the client device for display. The system may transmit a remaining subset of elements of the plurality of elements to the client device for display after the transmitting of the first subset of elements is complete. The augmented reality effect may be configured to launch and display at least one element of the first subset of elements prior to the remaining subset of elements is received by the client device.

Abstract: In one embodiment, a method for distributing an augmented reality (AR) effect may include ranking, by a computing system, a plurality of client devices based on a device capability, where a higher ranking may represent relatively better device capability. The system may identify a first subset of client devices having a first particular ranking. An AR effect may be transmitted to the first subset of client devices. The system may determine a performance score for the AR effect among the first subset of client devices. The performance score may be based on one or more performance parameters associated with the AR effect running on the first subset of client devices. The system may transmit the AR effect to a second subset of client devices when the performance score of the AR effect among the first subset of client devices satisfies a predefined threshold.
