Methods and systems for processing touch inputs are disclosed. The invention in one respect includes reading data from a multipoint sensing device such as a multipoint touch screen where the data pertains to touch input with respect to the multipoint sensing device, and identifying at least one multipoint gesture based on the data from the multipoint sensing device.

Gestures for touch sensitive input devices

Apparatus and methods are disclosed for simultaneously tracking multiple finger (202-204) and palm (206, 207) contacts as hands approach, touch, and slide across a proximity-sensing, compliant, and flexible multi-touch surface (2). The surface consists of compressible cushion (32), dielectric electrode (33), and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize the signal-to-noise ratio and to reduce wiring complexity. Scanning and signal offset removal on electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contacts 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 (245) which also detects individual contact touchdown and liftoff. 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.

Method and apparatus for integrating manual input

A method of generating a signal comprising providing a capacitive touch sensor pad including a matrix of X and Y conductors, developing capacitance profiles in one of an X direction and a Y direction from the matrix of X and Y conductors, determining an occurrence of a single gesture through an examination of the capacitance profiles, the single gesture including an application of at least two objects on the capacitive touch sensor pad, and generating a signal indicating the occurrence of the single gesture.

Object position detector with edge motion feature and gesture recognition

Disclosed herein is a multi-functional hand-held device capable of configuring user inputs based on how the device is to be used. Preferably, the multifunctional hand-held device has at most only a few physical buttons, keys, or switches so that its display size can be substantially increased. The multifunctional hand-held device also incorporates a variety of input mechanisms, including touch sensitive screens, touch sensitive housings, display actuators, audio input, etc. The device also incorporates a user-configurable GUI for each of the multiple functions of the devices.

Multi-functional hand-held device

Method and apparatus for detecting an operative coupling between one or more fingers or other appropriate objects and a touch pad includes processes for detection of multiple maxima with intermediate minima in appropriate sequences to emulate the operations of cursor control and button actuations in a pointing and control device.

Multiple fingers contact sensing method for emulating mouse buttons and mouse operations on a touch sensor pad

Methods and apparatus for data input. Devices (90) are provided in accordance with this invention which utilize capacitive coupling of an object (60) to the device (90) to sense the object's position. The devices (90) are comprised of a plurality of electrode strips (130) which form virtual electrodes (160, 170). The virtual electrodes are selectively connected to form virtual dipole electrodes (180, 190) which are responsive to the object's (60) position.
