Abstract

In recent years various usability issues related to device
characteristics of quantified-self wearables such as smartwatches and
pedometers have been identified which appear likely to impact device
adoption among the older adults. However, an overall framework has not
yet been developed to provide a comprehensive set of usability issues
related to smartwatches and pedometers. This study used a two-stage
research approach with 33 older participants, applying contextual action
theory and usability evaluation methods both to determine perceived
usability issues and to formulate a usability categorization framework
based on identified issues. Additionally, we prioritized the predominant
usability issues of smartwatches and pedometers that warrant immediate
attention from technology designers, the research community, and
application developers. Results revealed predominant usability issues
related to the following device characteristics of smartwatches: user
interface (font size, interaction techniques such as notification,
button location) and hardware (screen size); and of pedometers: user
interface (font size, interaction techniques such as notification,
button location, and tap detection) and hardware (screen size).
