Abstract

Described herein are finger registration systems and methods for use with a multi-touch device that can facilitate in place execution of commands or operations, thereby reducing focus switching and minimizing hand movement. The finger registration methods are simple and robust, using only contact points on the touch-based device, without requiring additional hardware. Direct mapping of operations to gestures involving individual fingers or combination of fingers (e.g., finger chords), provides a new and rich set of direct manipulation without focus switching for selecting commands/operations.
