Direct manipulation gestures

A computer-readable storage medium comprising instructions that, when executed, cause one or more processors to:

• receive an indication of a multipoint touch gesture that is performed with multiple touches at a touch interface;
• determine at least one physical simulation effect to associate with the resolved multipoint touch gesture, wherein the multipoint touch gesture comprises at least one of an unscrunch gesture, a shove gesture, a pile fan-out gesture, a pile-to-grid gesture, and a crop gesture;
• and
• output, for display at a graphical user interface, a unified feedback output action, wherein the unified feedback output action includes applying the at least one physical simulation effect to at least a graphical output action in the graphical user interface.

A computing device comprising:

• a touch interface to receive a multipoint touch gesture that is performed with multiple touches at the touch interface;
• a processor;
• a physical simulation module implemented by the processor to determine at least one physical simulation effect associated with the multipoint touch gesture, wherein the multipoint touch gesture comprises at least one of an unscrunch gesture, a shove gesture, a pile fan-out gesture, a pile-to-grid gesture, and a crop gesture;
• and
• wherein the multipoint input interface is configured to output a unified feedback output action in a graphical user interface, wherein the unified feedback action includes applying the at least one physical simulation effect to at least a graphical output action in the graphical user interface.
