Interactivity in Linear Diagrams

Linear diagrams have been shown to be an effective method for representing set-based data. Moreover, design principles empirically developed that, when followed, improve the efficacy of linear diagrams. These are task-independent. However, may produced aid with a variety tasks, which different representations more effective. In this paper, we introduce simple interactivity into Namely, gave users: ability move sets; overlaps (set-intersections); and focus diagram on particular group sets. Whether these interactions improved cognition was investigated via two empirical studies. first, observed that participants’ accuracy, confidence speed. second, improvements were based participants in first study, rather than being artefact itself. We conclude adding is useful case
