C.A.R.E : Designing a smartwatch app for older people
Abstract
The ageing population and age dependency ratio increases the need for systems that can help older people live independently. Smartwatches provide a new way to provide some of that support, but there is very limited research on acceptability and usability of smartwatches for this user group. Two studies initiated the design of an independent living smartwatch app for older users. A first study with participants aged 65 to 85 evaluated a high fidelity prototype of the app. This highlighted problems with gestures, colours, text and icons. This lead to a set of smartwatch app design guidelines for older users. A second user study evaluated two versions of the app developed with the guidelines. They were both considered useful and usable by older users, although reactions were more positive amongst “young old” participants than “old old” participants. Using the results of second user study, the guidelines for older users were refined.
