| Abstract: | The usability of knowledge domain visualization (KDViz) tools
can be assessed at several levels. Cognitive Walkthrough (CW) is
a well-known usability inspection method that focuses on how
easily users can learn software through exploration. Typical
applications of CW follow structured tasks where user goals and
action sequences that lead to achievement of the goals are welldefined.
KDViz and other information visualization tools,
however, are typically designed for users to explore data and user
goals and actions are less well understood. In this paper, we
describe how the traditional CW method may be adapted for
assessing the usability of these systems. We apply the adapted
version of CW to CiteSpace, a KDViz tool that uses bibliometric
analyses to create visualizations of scientific literatures. We
describe usability issues identified by the adapted CW and discuss
how CiteSpace supported the completion of tasks, such as
identifying research fronts, and the achievement of goals. Finally,
we discuss improvements to the adapted CW and issues to be
addressed before applying it to a wider range of KDViz tools. |
