Activity-tracking devices for older adults: comparison and preferences

Research demonstrates that physical activity beneficially influences brain function, quality of life and reduces cardiovascular diseases. Therefore, many projects and technical developments aim to promote physical activity. As a result of the “quantified self”-movement, a great number of wearable technologies, which are mainly developed for a younger target group, emerged on the market. However, there is a lack of scientific studies to establish which systems are suitable for older adults and there is still little known about seniors’ needs and preferences regarding fitness trackers. In this crossover-designed usability study, 20 older adults aged over 60 took part. In the study, all participants were requested to rate the usability of five of the most widely used fitness trackers (Nike FuelBand, Jawbone Up, Fitbit Flex, Garmin vivofit, Sony SmartBand) and were asked about their preferences. Participants had to rate its ergonomic features such as handling, material and design. Overall, the fitness trackers differ a lot in tracking features, design, usability and acceptance of the seniors. We present an aggregated list of requirements for the “ideal” activity tracker for older adults. The results seem to be of high interest for developers, but also for scientists to choose appropriate sensors for technology-based interventions that may promote physical activity.
