Abstract: Embodiments related gesture-based inputs made via multi-touch display are disclosed. One disclosed embodiment comprises a computing device configured to detect a modal touch input on a multi-touch display, the modal touch input having a geometrically defined posture. In response, the computing device is configured to set a selected touch input mode based on the posture of the first modal touch input, the touch input mode representing a relational correspondence between a first set of functional touch inputs and a first set of functions. The computing device is further configured to detect a functional touch input on the multi-touch display, to determine the relational correspondence between the functional touch input and an associated function included in the set of functions based on the touch input mode, and to modify the multi-touch display based on the associated function.
