Abstract
This article examines the use of pervasive computing for the provision of care in the community for frail older people living alone in their own homes. The concept of well-being is explored using a conceptual framework that incorporates person, context, everyday activities, personal meanings, and well-being outcomes. The article reviews the implications of this model for developing a practical system within the home of an older person using nonintrusive pervasive sensors and computing devices to monitor indicators of his or her well-being. The data from sensors in the home can be used to detect trends in 6 key activities, which might be indicators of changes in the functional, psychological, and social status of the person. The aim of the well-being monitoring system is to provide care workers and carers with an intuitive early warning system to allow appropriate care interventions, leading to improved care services and an enhanced quality of life for the individual.
