Abstract

This paper shows how information visualization techniques can be used to improve the effectiveness of task model representations. In particular, we discuss how fisheye and semantic-zoom representations have been used to improve the effectiveness of the ConcurTaskTrees notation. The approach can also be useful for improving other visual modelling languages. We also report on a first evaluation of the proposed representations.
