WritLarge is a freeform canvas for early-stage design on electronic whiteboards with pen+touch input. The system aims to support a higher-level flow of interaction by 'chunking' the traditionally disjoint steps of selection and action into unified selection-action phrases. This holistic goal led us to address two complementary aspects: SELECTION, for which we devise a new technique known as the Zoom-Catcher that integrates pinch-to-zoom and selection in a single gesture for fluidly selecting and acting on content; plus: ACTION, where we demonstrate how this addresses the combined issues of navigating, selecting, and manipulating content. In particular, the designer can transform select ink strokes in flexible and easily-reversible representations via semantic, structural, and temporal axes of movement that are defined as conceptual 'moves' relative to the specified content.
