This document specifies the AAL reference architecture. This document describes a reference architecture for AAL to guide the development and deployment of AAL services and technologies. This document defines concepts and introduces terminology. The reference architecture provides generic rules for designers of AAL systems and services with the aim to facilitate systems design and enable interoperability between components. The standard differs from DIN IEC 63240-1 (VDE 0754-5-1):2021-12 as follows: a) clarifying the Introduction; b) new terms and definitions have been added in 3.1; c) adaption of terms according to the IEV in the whole document; d) reference to ethical considerations of AI when applied in the AAL context has been added in Clause 5; e) clarifying the description of AAL reference architecture in 6.3.1; f) process to identify the needs on BAN, edge and cloud computing in the architecture perspective has been added in 6.3.2 and 6.3.3; g) new figures have been added in 6.3.2 and 6.3.3; h) reference to standards inventory has been added in 7.1; i) clarification of 7.5; j) Annex A has been added; k) updated bibliography.
