Interaction Strategies for Scatterplot Visualizations on Small Screens
Keywords: Punktdiagramme, Zoomable User Interface, Kleine Bildschirme, PDA, Fischauge
This article presents two novel systems for the visualization and exploration of large information spaces on small screens. The applications feature a scatterplot view that encodes abstract data to small-scale visual representations and thus provides a valuable solution to enhance the limited screen real estate of small devices. Another benefit of the scatterplot is that it provides an overview of the information space. Looking at the diagram, even novice users are able to quickly identify trends and statistical outliers.
The two systems presented here differ in their interaction strategies. The geometric-semantic ZUI stands for a metaphorbased, intuitive approach and, in some aspects, it reminds of a computer game. Users can dynamically adjust the ratio of overview and detail information according to their current need. The alternative system features a fisheye view and allows users to magnify any portion of the diagram. Based on a distortion algorithm, data clutter can be removed while, at the same time, the context of the diagram is preserved. The preservation of context supports users in navigating the information space and also allows for the implementation of additional interaction facilities.
