Abstract

Information visualization systems often present usability problems mainly because many of these tools are not submitted to complete evaluation studies. This paper presents an experimental study based on tests with users to evaluate two multidimensional information visualization techniques, Parallel Coordinates and Radviz. The tasks used in the experiments were defined based on a taxonomy of users' tasks for interaction with multidimensional visualizations. The study intended to identify usability problems following the ergonomic criteria from Bastien and Scapin on implementations of both techniques, especially built for these experiments with the InfoVis toolkit.
