Foreword
This Group Specification (GS) has been produced by ETSI Industry Specification Group (ISG) Augmented Reality
Framework (ARF).
The present document is part 5 of a multi-part deliverable covering Interoperability Requirements for AR components,
systems and services, as identified below:
Part 1: "Overview";
Part 2: "World Storage and AR Authoring functions";
Part 3: "World Capture, World Analysis and Scene Management";
Part 4: "World Analysis, World Storage and Scene Management functions (AR8, AR10, AR11)";
Part 5: "External Communications".
The ISG ARF shares the following understanding for Augmented Reality: Augmented Reality (AR) is the ability to mix
in real-time spatially-registered digital content with the real world. The present document specifies the interoperability
requirements for Reference Points AR1 and AR2 of the reference architecture for AR solutions defined in ETSI
GS ARF 003 [1].
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
