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.

A notepad computer is disclosed with a page display region displaying a page of a document on which a user can write using a pen. Associated with the page is an interface useable with the pen including a core task tool region where tool icons are partially visible until the pen is brought near a tool icon. A radial menu pops up at an edge of the document where menu choices are located in a semi-circle away from the edge. A page flipping tool is also provided. A page scrolling tool is further provided that, when activated, includes an implicit button allowing scrolling in one implied direction. A stack region adjacent to the page display region has stack icons each representing a stack of documents. A typing tool is also provided overlaying a portion of the page and including a writing zone and a page zone.
