Industry Specification Group (ISG) Augmented Reality Framework (ARF) Activity Report 2021

Chair: Muriel Deschanel, b-com (until 13 December 2021). New Chair: Jens Johann, Deutsche Telekom AG

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

Augmented Reality (AR) blends real-time spatially registered digital content with our experience of the real world. Transparent and reliable interworking between different AR components is key to the successful roll-out and wide adoption of AR technologies and services.

Our Industry Specification Group on Augmented Reality Framework (ISG ARF) is defining a framework for the interoperability of Augmented Reality components, systems, and services. Allowing components from different providers to interoperate through defined interfaces, this framework avoids vertical silos and reduce market fragmentation – and thus enables players in the ecosystem to offer parts of an overall AR solution.

Primary responsibilities of the group are:

  • To ensure that Augmented Reality (AR) services and platforms will be easier to design, deploy and operate than today, taking into account the advent of 5G networks.
  • To enable the development of high-performance AR components which are portable between different hardware vendors and different providers of software solutions and platforms.
  • To achieve co-existence of legacy and proprietary platforms whilst enabling an efficient migration path to fully interoperable platforms for AR solutions.

In Q3 2021 ISG ARF published its multi-part Group Report and Specification on Interoperability Requirements for AR components, systems, and services, comprising:

New Work Items were also created during the year, addressing the interoperability requirements detailed in GS ARF 004-2:

  • Definition, specification, documentation, and validation of the API that meets the requirements relative to the World Storage and pose cluster. The result will be the publication of a GS defining in OpenAPI format, the data structures, API calls and exchange protocols required to create and manage the World Graph stored in the World Storage function (DGS/ARF-005).
  • The implementation of wrappers for existing World Storage solutions satisfying the APIs for the Creation and Management of the World Representation (DMI/ARF-006).

In Q3 the group launched work on a new Standards Landscape report, based on an existing functional reference model defined in GS ARF 003.

Publication of the above deliverables is anticipated in 2022.

In October ISG ARF was active at the ISMAR 2021 conference, participating in the tutorial ‘Introduction to Augmented Reality Interoperability and International Standards’.

During the year ISG ARF continued its close collaboration with external bodies The AREA, Khronos Group and the Open AR Cloud Association (OARC). These liaisons allow the exchange of views and expertise, enable coordination of work activities, foster collaboration 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. The group has also maintained its active liaison exchange with ETSI groups (e.g. ISG MEC) and 3GPP SA WG4 group.

Membership of ISG ARF continued to increase over the course of the year. 18 ETSI members and 11 non-ETSI members have now signed the ARF agreement.
