A network-based approach for evaluating ambient assisted living (AAL) technologies.
Abstract.Ambient assisted living (AAL) technologies could support people experiencing physical or cognitive challenges, to and maintain social identities and complex activities of daily living.Although there has been substantial investment in developing AAL innovation, less effort has been devoted to understanding how to evaluate the impact of AAL on physical and mental health. Taking a theory-based evaluation approach, we suggest that AAL technologies rely on networks of people and organisations to function, and analysing the changing structure of networks can bridge the gap between socio-technological change and individual-level capabilities. We present conceptual arguments for taking a network perspective in AAL evaluations, illustrated with examples from our own group's work on technology use among older people with cognitive impairments. We then discuss the different evaluation questions that could be addressed by 'ego-centred' and 'global' network analysis. Finally, recognising the creative ways people mobilise technology for themselves, and the unanticipated effects of technology, we underline the importance of qualitative, observational, and ethnographic approaches in unpicking the processes of change brought about when new technologies are introduced.
