Gesture-supported document creation on pen and touch tabletops

We present an ongoing effort to design and implement a prototype system for pen and touch-operated digital workdesks supporting the activity of document creation. Our application exploits bimanual gestures to perform common document editing operations including element manipulations, text input, clipart retrieval and insertion in a mostly direct way. For many of our gestures, we rely on pen-mode switching actions triggered by postures of the non-dominant hand, which allows us to provide a largely widget-free yet efficient user interface
