There is an increased recognition of the potential of assistive technologies to address the challenges of an aging population and the ongoing requirements of older people. To ensure that technology is reflective of the information technology needs of older people, and that it supports independence and well-being, there is a requirement that users are involved in the application and development of proposed interventions. This challenge has stimulated a programme of research across the European Union designed to develop AAL responses to assist older people in their everyday lives. This chapter describes a case study from an EU funded project which adopted a user-centred approach to the development of assistive technology amongst community-dwelling adults. The research process and the lessons from it are presented, whilst identifying key challenges for the inclusion of older people in the research and development process.
