Method for Operating a Server-Based Master Database for a Multi-User Collaborative Augmented Reality System

Abstract: a location-based, multiuser, collaborative augmented reality (ar) system employs individual ar devices for viewing real-world anchors, that is, physical models that are recognizable to the camera and image processing module of the ar device. multiple, distinct ar sessions can coexist at the same physical site, and those sessions can be offered to ar devices at the site. session initiators can manage who can join and/or to whom invitations to join are extended. the system permits collaborative ar to span multiple sites, by associating a portal with an anchor at each site. using the location of their corresponding ar device as a proxy for their position, ar renditions of the other participating users are provided. this ar system is particularly well suited for games.
