IceTT: a responsive visualization for task models

Task models are useful for designers and domain experts in order to describe sequences of actions that need to be completed for reaching a user's goal. Their hierarchical structure is usually visualized through a tree representation that, for large models, is inclined to grow horizontally and reduces its readability. In this paper we introduce a visualization based on icicle graphs, which is able to adapt the tasks visualization to the screen width, suitable for displaying large models even on small screens.
