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 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.
