Book excerpt: The challenge of population aging requires innovative approaches to meet the needs of increasing numbers of older people. Emerging information and communication technologies (ICTs), such as pervasive computing and ambient assistive technology, have considerable potential for enhancing the quality of life of many older people by providing additional safety and security while also supporting mobility, independent living, and social participation. The proposed book will be a landmark publication in the area of technology and aging that will serve as a statement of the current state-of-the-art and as a pointer to directions for future research and emerging technologies, products, and services.
