TouchPivot: Blending WIMP & Post-WIMP Interfaces for Data Exploration on Tablet Devices
summary
A tablet interface called TouchPivot combines shelf-style WIMP controls with pen and touch gestures to pivot, filter, and remap data while keeping table and chart tightly linked with animated transitions. A gesture vocabulary (three touch and four pen gestures) and rules like forbid pivoting by numeric fields reduce error-prone transforms. A between-subjects study on 48 participants versus Tableau and Excel PivotTable runs on Surface Pro 3, finding faster task completion and more correct, meaningful charts during open exploration.
