A framework for evaluating Ambient Assisted Living technologies and the experience of the universAAL project

Abstract:

Ambient Assisted Living (AAL) technologies aim at supporting elderly and disabled people in their environment, with affordable, easy to use and meaningful ICT tools. Given the complexity of AAL, software platforms are needed to abstract and reuse typical functionalities. To this purpose, the universAAL project was established to create an open platform that provides a standardized approach making it technically feasible and economically viable to develop AAL solutions. In order to make AAL technologies widely accepted, high quality must be guaranteed, but measuring quality in AAL is difficult because of the variety of stakeholders, the wide set of needs addressed and the heterogeneity of the employed technologies. This paper proposes a methodological framework for evaluating AAL solutions with the aim of prioritizing evaluation needs, customizing assessment techniques and producing value for the project. The framework is based on empirical methods and on scientific-like theory building mixed with the standard ISO/IEC 25000 for software quality. It can be applied for both technical and non-technical (end-user) evaluations. To support the framework, the results of its application in universAAL are shown, i.e., how it was used at different stages of the project for assessing the results, for taking decisions and for building scientific knowledge.
