VizInteract is an interactive data visualization tool for touch-enabled displays. It affords rapid construction of multidimensional data visualizations through multi-touch gestures, which supports efficient data exploration. Creating and analyzing multidimensional data visualizations with current tools typically involve complex user interfaces. Building on primitive visualization idioms like histograms, VizInteract addresses the need for easy data exploration by affording the rapid construction of multidimensional visualizations, such as scatter plots, parallel coordinate plots, and radar plots through simple touch gestures. Touch-based brushing-and-linking and attribute-based filter-bubbles also support “diving down” into the data and performing analyses. I conducted two explorative studies to demonstrate the usability of VizInteract on a tablet and on a large touchscreen. I present the results of both studies and analyse the usage patterns that emerge from participants conducting data exploration VA tasks in both conditions.
