Apparatus and methods are disclosed for simultaneously tracking multiple finger and palm contacts as hands approach, touch, and slide across a proximity-sensing, compliant, and flexible multi-touch surface. The surface consists of compressible cushion dielectric, electrode, and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize signal-to-noise ratio and to reduce wiring complexity. Such distributed transduction circuitry is economical for large surfaces when implemented with thin-film transistor techniques. Scanning and signal offset removal on an electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contact and extracts shape, position and surface proximity features for each group. Groups in successive images which correspond to the same hand contact are linked by a persistent path tracker which also detects individual contact touchdown and liftoff. Combinatorial optimization modules associate each contact's path with a particular fingertip, thumb, or palm of either hand on the basis of biomechanical constraints and contact features. Classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.

What is claimed is: 1. A method for mapping gestures to graphical user interface commands, the method comprising generating a cut command in response to a pinching motion between a thumb and a fingertip detected on a multi-touch-sensitive surface. 2. The method of claim 1 further comprising generating a copy command in response to a synchronized tap of a thumb and a fingertip detected on the multi-touch-sensitive surface. 3. The method of claim 2 further comprising generating a paste command in response to a movement of the thumb and a fingertip away from each other detected on the multi-touch-sensitive surface. 4. The method of claim 1 further comprising generating a paste command in response to a movement of the thumb and a fingertip away from each other detected on the multi-touch-sensitive surface. 5. A method for mapping gestures to graphical user interface commands, the method comprising generating a copy command in response to a synchronized tap of a thumb and a fingertip detected on a multi-touch-sensitive surface. 6. The method of claim 5 further comprising generating a paste command in response to a movement of the thumb and a fingertip away from each other detected on the multi-touch-sensitive surface. 7. A method for mapping gestures to graphical user interface commands, the method comprising generating a paste command in response to a movement of the thumb and a fingertip away from each other detected on a multi-touch-sensitive surface. 8. The method of any of claims 1-7 further comprising generating mouse manipulations by: generating mouse pointer motion signals in response to translational slides of a predetermined number of fingertips detected on the multi-touch-sensitive surface; and generating mouse drag signals in response to translational slides of a second predetermined number of fingertips detected on the multi-touch-sensitive surface. 9. The method of claim 8 further comprising generating text cursor manipulations by: generating text cursor motion signals in response to translational slides of a third predetermined number of fingertips detected on the multi-touch-sensitive surface; and generating text selection signals in response to translational slides of a fourth predetermined number of fingertips detected on the multi-touch-sensitive surface. 10. The method of claim 9 wherein mouse manipulations are performed with a first hand and text cursor manipulations are performed with an opposite hand. 11. The method of claim 10 wherein the first and third predetermined number of fingertips are equal and wherein the second and fourth predetermined number of fingertips are equal. 12. The method of any of claims 1-7 further comprising generating text cursor manipulations by: generating text cursor motion signals in response to translational slides of a first predetermined number of fingertips detected on the multi-touch-sensitive surface; and generating text selection signals in response to translational slides of a second predetermined number of fingertips detected on the multi-touch-sensitive surface.
