Abstract: An augmented reality (AR) platform supports concurrent operation of multiple AR applications developed by third-party software developers. The AR platform may include an application programming interface (API) that third-party software developers can use to integrate features of the AR platform into the overall user experience of their AR applications. The AR platform includes a feature set having a variety of AR-specific features that interact with and are accessible to the AR applications or AR layers that define a collection of AR content.

Abstract: A system for accurately positioning augmented reality (AR) content within a coordinate system such as the World Geodetic System (WGS) may include AR content tethered to trackable physical features. As the system is used by mobile computing devices, each mobile device may calculate and compare relative positioning data between the trackable features. The system may connect and group the trackable features hierarchically, as measurements are obtained. As additional measurements are made of the trackable features in a group, the relative position data may be improved, e.g., using statistical methods.

Abstract: A method and system are provided for enabling a shared augmented reality experience. The system may include one or more onsite devices for generating AR representations of a real-world location, and one or more offsite devices for generating virtual AR representations of the real-world location. The AR representations may include data and/or content incorporated into live views of a real-world location. The virtual AR representations of the AR scene may incorporate images and data from a real-world location and include additional AR content. The onsite devices may synchronize content used to create the AR experience with the offsite devices in real time, such that the onsite AR representations and the offsite virtual AR representations are consistent with each other.

Abstract: A system is provided for enabling a shared augmented reality experience. The system comprises zero, one or more on-site devices for generating augmented reality representations of a real-world location, and one or more off-site devices for generating virtual augmented reality representations of the real-world location. The augmented reality representations include data and or content incorporated into live views of a real-world location. The virtual augmented reality representations of the AR scene incorporate images and data from a real world location and include additional content used in an AR presentation. The on-site devices synchronize the content used to create the augmented reality experience with the off-site devices in real time such that the augmented reality representations and the virtual augmented reality representations are consistent with each other.
