universAAL - AAL Reference architecture requirements

D1.2 reports about the requirements analysis process in universAAL and summarizes the related results. The current document, D1.2-A due at month three, is the first report from four planned versions. It deals with the initialization phase of the requirements analysis process. In this phase, a starting set of requirements are worked out based on the consolidation of requirements already identified by the input projects GENESYS, MPOWER, OASIS, PERSONA, and SOPRANO. D1.2-B due at month 12 will be the main version defining the actual universAAL reference requirements. Section 2 provides more details on the purpose of D1.2, its relationships to the other universAAL deliverables as well as the positioning of D1.2-A in relation to the other versions of D1.2. Consolidation is the main motif in the universAAL project in order to benefit from the plenty of high quality engineering work already done in the field of Ambient Assisted Living. It should help to reach consensus in the research community and a wider acceptance in the general public based on the provision of a set of converging conclusions. To assure ourselves of the quality of the input set of requirements, we first checked the requirements analysis process in each of the input projects and the used engineering tools and techniques. The results of this survey are summarized in Section 3. Section 4 is the main part of this report that describes the engineering works in universAAL towards the provision of a first consolidated version of the requirements in AAL. It introduces the ARCADEbased methodology for collecting the input requirements in a harmonized way, mapping them to each other, and providing a first prioritization of the resulted set of requirements. The output of this process is included in form of a table in the appendix of this report. The report concludes with some advice for the next phases of work, especially towards D1.2-B with the AAL reference requirements.
