Implementing ALiS: Towards a Reference Architecture for Augmented Living Spaces

Abstract

Augmented reality (AR) is currently discussed as an approach to promote the personal health of elderly and cognitively impaired people, with spatial AR being a promising, wearable-less solution to enable an augmented living space (ALiS) that immersively provides and communicates individual, needs-oriented functionalities in the areas of perception, mobility, organization, and medicine. To address the knowledge gap of missing knowledge concerning the implementation of such assistance systems that support autonomy in everyday life, we derived a reference architecture (RA) based on an existing design theory. Our RA contains UML diagrams for components and sequence flows, accompanying text descriptions, and a user interface design. We successfully implemented a prototype to show the RAs feasibility and conducted an expert survey for its general usefulness with positive results. Our contributions add to the prescriptive knowledge base of the community as the results may be adapted by researchers and practitioners.
