Using clear and accessible language this book examines the growing field of 'smart techlogy' for the home. The author first introduces the field before exploring the various background issues, including how the home differs from other environments. He then shows how these background issues affect the design and usability of these techlogies. A detailed case study looks at the use of handheld and wearable digital techlogy in sheltered housing. The last section examines what it is like to live in a smart home and why they have so far failed to reach the levels of success originally predicted. Invaluable reading for anybody interested in designing smart techlogies for the home.
