Abstract

TableVis was developed to support computer users, who are blind or visually impaired in tasks that involve obtaining quick overviews of tabular data sets. An iterative design methodology led to a successful solution to this problem, as derived from evaluations of the interface and its associated techniques for interactive data sonification and support of exploratory processes. However, complex systems can be used creatively in a variety of ways, which are often different from those intended by their designers. Thus, it can be difficult to determine the specific reasons that make a complex interface successful. In an attempt to find a way around these limitations in the most commonly used usability test methodologies, the exploratory strategies and procedures employed by users in their evaluations of TableVis were analysed. These analyses provided a better understanding of the challenges in exploratory tasks from the perspective of users with visual impairments, and helped to identify both best practices and common problems, which form the basis for the next steps to be taken in this line of research.
