Industry Specification Group (ISG) Augmented Reality Framework (ARF) Activity Report 2020

Chair: Muriel Deschanel, b<>com

Responsible for defining an interoperability framework for Augmented Reality (AR) applications and services, enabling players in the chain to offer part of an overall AR solution and thus avoid market fragmentation.

Augmented Reality (AR) blends real-time spatially registered digital content with our experience of the real world. Our Industry Specification Group on Augmented Reality Framework (ISG ARF) is defining a framework for the interoperability of Augmented Reality components, systems and services.

Transparent and reliable interworking between different AR components is key to the successful roll-out and wide adoption of AR technologies and services. Allowing components from different providers to interoperate through defined interfaces, this framework will avoid vertical silos and reduce market fragmentation, enabling players in the eco-system to offer parts of an overall AR solution.

Published in 2020 and building on previous deliverables, the group’s first Group Specification [GS ARF003] defines a modular reference architecture, forming the basis of the interoperability framework for industrial AR components, systems and services. This reference architecture identifies and describes key components and interfaces required by an AR solution, this is the first step to enable components from different providers to interoperate via the defined interfaces.

Work meanwhile started on the development of interoperability requirements: four sets of Reference Points/interfaces were identified by the group as being key for interoperability and of highest interest to the group membership. Significant progress was made on the initial cluster of Reference Points around the ‘real world model’.

Replacing a planned physical event, our successful virtual workshop ‘Engineering XR for the Future: Frameworks, Requirements and Future Research’ - jointly organised with the AREA and the H2020 EU-funded XR4ALL project - attracted a wide international viewing audience.

During the year ETSI signed two Memoranda of Understanding (MoUs) with the Khronos Group and OARC (Open AR Cloud Association). Allowing the exchange of views and expertise, the MoUs enable ETSI and both organizations to coordinate work activities, collaborate on the interoperability of AR components, systems and services, and contribute to the development of a thriving eco-system with a diverse range of technology and solution providers.

ISG ARF maintained ongoing liaison with other groups including ETSI’s Industry Specification Group MEC (Multi-Edge Computing), ISO/IEC MPEG, 3GPP and GSMA which have ongoing work relevant to the activity of the group.

During 2020 membership of ISG ARF grew to 24 organizations.
