Usability and Usefulness in Assistive Technology for Cognitive Support in Respect to User Goals

Abstract

The aim of this study was to examine the usability of different assistive technology (AT) products for cognitive support by identifying features that promoted and/or impeded cognitively impaired users' performance of tasks that were identified as hindering engagement in valued activities. An additional aim was to examine how the users could reach their goals and expected gains as a result of the support of the AT, that is, the usefulness of the AT. During two six month interventions, persons who had experienced a stroke or had Alzheimer's disease tried out AT for cognitive support that intended to meet their needs and desires. Data from interviews and field notes collected during the intervention periods were analysed. One hundred identified factors judged as promoting or impeding the performance of the tasks and/or the user goals, were categorised. The findings are shown in seven preliminary themes that focus on the interaction between the user and the AT and, further, on how the AT is customised to the user's needs and incorporated into the user's own everyday context.
