Abstract: In one embodiment, a method includes receiving first information from a sensor associated with a first computing device, wherein the first information comprises information associated with first images captured at the first sensor; receiving second information from a second computing device, wherein the second information comprises information associated with second images captured at a sensor associated with the second computing device; identifying first points within the first images; identifying second points within the second images; and relocalizing the first and second computing devices within a shared augmented-reality environment by defining coordinate spaces based on the images and combining the coordinate spaces based on identified shared points.

Abstract: In one embodiment, a method includes generating, by a device, first tracking data using a first tracking algorithm, based on first video frames associated with a scene. An augmented-reality (AR) effect may be displayed based on the first tracking data. The device may generate a first confidence score associated with the first tracking data and determine that the first confidence score is above a threshold. The device may generate, based on second video frames subsequent to the first video frames, second tracking data using the first tracking algorithm. The device may determine that an associated second confidence score is below a threshold. In response, the device may generate, based on third video frames subsequent to the second video frames, third tracking data using a second tracking algorithm different from the first. The device may then display the AR effect based on the third tracking data.

Abstract: In one embodiment, a method includes rendering an augmented-reality environment on a display associated with a first computing device associated with a first user; identifying one or more objects within the augmented-reality environment; determining a suggested augmented-reality content item based on social-networking information associated with the first user, and further based on characteristics associated with the identified objects; and presenting the suggested augmented-reality content item on a display associated with the first computing device.

Abstract: In one embodiment, a method includes rendering an augmented-reality environment on a display associated with a first computing device that is associated with a first user; determining that the first computing device is authorized to access an augmented-reality content item associated with a location within the augmented-reality environment based on social-networking information associated with the first user, wherein the augmented-reality content item is associated with a second user; receiving, by the first computing device, information configured to render the augmented-reality content item at the associated location within the augmented-reality environment; and rendering, on the display associated with the first computing device, the augmented-reality content item within the augmented-reality environment.

Abstract: Systems, methods, and non-transitory computer readable media are configured to receive a user request to identify at least one object of an environment in which a computing device is situated. A classification for the at least one object can be received. Subsequently, an audio tag based on the classification for the at least one object can be placed in a representation of the environment. The audio tag can be associated with a sound perceived by a user to be emanating from the least one object.
