Abstract

<p>This paper discusses a method for evaluating effects of assistive technologies through long-term fluctuations in user dialogue and experienced self-efficacy. A study was performed with 15 physically disabled interviewees who were working from home and using personal computers. Interviewees were asked to rate self-efficacy at particular times coinciding with their introduction to an assistive technology, training and employment. Based on dialogue with each user, these turning points and time fluctuations were drawn on a graph with time as the x-axis. The results showed that fluctuations were influenced by a combination of time-sensitive factors rather than by a single static factor. This method of building a time-line graph of user experience is proposed as a way to evaluate assistive technologies more thoroughly, documenting success and failures associated with the introduction of assistive technologies, and providing some sights into why those successes and failures occurred.</p>
