Pinch: An interface that relates applications on multiple touch-screen by 'pinching' gesture

Abstract

We devised a new user interface that relates applications running on multiple mobile devices when the surfaces of juxtaposed screens are merely pinched The multiple-screen layout can be changed dynamically and instantly even while applications are running in each device This interface can introduce a new kind of interaction: rearrangement of devices triggers a certain reaction of contents We expect this interface to show great potential to inspire various application designs, and we expect to enrich the contents by offering interaction that a single display or a static multi-display environment cannot provide To prove and demonstrate that the interface is functional, we implemented a framework for using the interface and developed several applications using it Although these applications are simple prototypes, they received favorable responses from audiences at several exhibitions © 2012 Springer-Verlag Berlin Heidelberg.
