RT Journal Article T1 TV interaction as a non-invasive sensor for monitoring elderly well-being at home A1 Abreu, Jorge A1 Oliveira, Rita A1 García Crespo, Ángel A1 Rodriguez Goncalves, Roxana AB The number of technical solutions to remotely monitoring elderly citizens and detectinghazard situations has been increasing in the last few years. These solutions have dual purposes: toprovide a feeling of safety to the elderly and to inform their relatives about potential risky situations,such as falls, forgotten medication, and other unexpected deviations from daily routine. Most ofthese solutions are based on IoT (Internet of Things) and dedicated sensors that need to be installedat the elderly’s houses, hampering mass adoption. This justifies the search for non-invasive technicalalternatives with smooth integration that relying only on existent devices, without the need for anyadditional installations. Therefore, this paper presents the SecurHome TV ecosystem, a technicalsolution based on the elderly’s interactions with their TV sets—one of the most used devices in theirdaily lives—acting as a non-invasive sensor enabling one to detect potential hazardous situationsthrough an elaborated warning algorithm. Thus, this paper describes in detail the SecurHome TVecosystem, with special emphasis on the warning algorithm, and reports on its validation process.We conclude that notwithstanding some constraints while setting the user’s pattern, either upon thecold start of the application or after an innocuous change in the user’s TV routine, the algorithmdetects most hazardous situations contributing to monitor elderly well-being at home.
