EvAAL2 aims to develop concrete measurement instruments for evaluating the impact of AAL solutions, with a focus on three specific application areas. The instruments developed are characterized by a holistic approach, incorporating subjective, institutional, and societal aspects, as well as a high degree of practical applicability. This is intended to encourage their use in practice and ensure comparability in the evaluation of AAL products and services. To ensure high quality standards, several feedback loops are planned, including the involvement of stakeholders and experts as well as quantitative pre-tests.
