The overall aim of the A.C.T.I.O.N. research project (Assisting Carers using Telematic Interventions to meet Older person's Needs) is to maintain or enhance the autonomy, independence and quality of life of frail older and disabled people and their family carers by providing information, advice and support in the home. The authors report on the first phase of evaluation conducted using a case-study approach to test the A.C.T.I.O.N. system in several family carers' homes in Sheffield, England.
