In this article we explore the design space of gesture shortcuts on touchpad with four novel interaction techniques: SpotPad and LociPad rely on one-finger static gestures, but differ in their graphical representation (Grid vs. loci). ChordPad relies on two-finger static gestures with a hierarchical representation. Finally, InOutPad relies on dynamic gestures crossing the edges of the touchpad. We present and compare the properties of these techniques of interaction and describe how they can be deployed on Mac OS X.
