Healthcare, social welfare and housing policy agendas, while emphasising the importance of supporting the independent living of older people at home, have generally failed to take account of the actual or potential role played by social alarms and telecare. This book draws on research and practice throughout the developed world. It documents the emergence of these important technologies and considers their potential in the contexts of healthcare, social welfare and housing. The book is of immense importance to policy makers and practitioners in healthcare, social welfare and housing. It signals the potential, the challenges and the threats associated with such technologies. As such it must be compulsory reading for every current or potential service provider.
