Augmented Reality Framework (ARF); AR framework architecture

The present document specifies a functional reference architecture for AR components, systems and services. The structure of this architecture and the functionalities of its components have been derived from a collection of use cases, ETSI GR ARF 002 (V1.1.1): Augmented Reality Framework (ARF) Industrial use cases for AR applications and services, and an overview of the current landscape of AR standards, ETSI GR ARF 001 (V1.1.1): Augmented Reality Framework (ARF); AR standards landscape. The present document introduces the characteristics of an AR system and describes the functional building blocks of the AR reference architecture and their mutual relationships. The generic nature of the architecture is validated by mapping the workflow of several use cases to the components of this framework architecture.
