Identification of age-specific usability problems of smartwatches

Abstract

Since new technology is, in principle, accessible to users of all ages, it needs to be suitable for all generations. The purpose of this study is to identify usability issues of smartwatches and contrast the problems and issues that elderly encountered to those experienced by a younger age group. In total 16 test subjects, eight of each age group (under-30s and over-60s), were observed quantitatively and qualitatively while performing basic tasks on a common smartwatch. The results indicate that the voice command evoked issues for all ages, whereas the older participants were facing more difficulties concerning the menu structure, the user interface and performing gestures on the touchscreen. While the task completion rate did not significantly differ between the age groups and the ease of use was mostly perceived equally, the elderly needed significantly more time and more personal assistance to perform the tasks. Understanding the likely age-specific differences in smartwatch interaction points to a need for further support for the elderly.
