A 2-year randomized controlled trial conducted to test the feasibility and effectiveness of currently available smart home technology compared 46 treatment and 67 control home-based frail elders who lived alone. Treatment group participants were provided with a computer with Internet access and X10-based smart home technology. Problems in the use of the technology were categorized into 4 areas: person, computer, X10 products, and home. For each area, solutions were identified. Participants benefited from the smart home technology, and 91% recommended its use by others. The treatment group maintained physical and cognitive status, whereas the control group declined significantly in both.
