Abstract
A system for identifying an AR tag and determining a location for a virtual object within an augmented reality environment corresponding with the AR tag is described. In some environments, the location of a virtual object corresponding with a particular AR tag may be determined by identifying a predefined object, determining an orientation and a scale of the predefined object relative to a head-mounted display device (HMD) based on a model of the predefined object, and inferring the location of the virtual object based on the orientation and the scale of the predefined object. In some cases, an identification of the particular AR tag corresponding with the virtual object may be acquired by aggregating and analyzing individual identity determinations from a plurality of HMDs within an augmented reality environment.
