This paper reports the findings of a literature review conducted to investigate user responses to assisted living technologies (ALTs), principally telehealth and telecare applications. A combination of search terms identified approximately 75 relevant publications, including reports of studies in the US, Australia, Europe and the UK. The documents were analysed to extract data relating to end-user needs, what attracts end users and informal carers to telehealth/telecare services, and what deters them from adopting these technologies. Some key challenges arising for the uptake and adoption of ALTs are then discussed, and significant user requirements emerging from the evidence are identified. The paper concludes with suggestions for the next steps to be taken to promote effective and appropriate use of ALTs.
