Abstract: Aspects of the present disclosure are directed to creating interactive avatars that can be pinned as world-locked artificial reality content. Once pinned, an avatar can interact with the environment according to contextual queues and rules, without active control by the avatar owner. An interactive avatar system can configure the avatar with action rules, visual elements, and settings based on user selections. Once an avatar is configured and pinned to a location by an avatar owner, when other XR devices are at that location, a central system can provide the avatar (with its configurations) to the other XR device. This allows a user of that other XR device to discover and interact with the avatar according to the configurations established by the avatar owner.

Abstract: An approach to structured record retrieval permits transmission and storage of records in a native concise format, without requiring that the records be interpreted and stored in a tabular form. Such storage of the records in a tabular form might double the space required, and more generally, requires substantially more space in applications in which there are many optional elements. In some embodiments, each message is parsed according to a specification of the message structure (e.g., according to a “grammar” for the message), and during parsing field values in predefined positions in the structure are extracted and added to an index structure that associates record identifiers with the (position, value) pairs.
