The method includes generating a CGR file including data regarding the CGR scene, the CGR file including data regarding the anchor, the CGR objects, and the behavior.

Abstract: The disclosed computer-implemented method may include receiving a first input from a first artificial reality device detecting a first environment of a first user and determining a first environmental feature of the first environment based on the first input. The method may include receiving a second input from a second artificial reality device detecting a second environment of a second user and determining a second environmental feature of the second environment based on the second input. The method may include comparing the first environmental feature with the second environmental feature and including, based on the comparison, the first and second users in a group for online interactions. Various other methods, systems, and computer-readable media are also disclosed.
