Abstract: A method is provided for a user interface recognizing the interruption of the execution of a first gesture with the execution of a second gesture. Measured information responsive to user interaction actions made by a user is received from a user interface sensor. At least one operation is applied to the measured information to produce a sequence of symbols or gestemes. The sequence of symbols is first used to determine that the user's execution of a first gesture has been interrupted. The sequence of symbols is used to determine that the user's execution of a second gesture has been started and completed resuming the first gesture. The sequence of symbols is used to determine that the user's execution a first gesture has been completed. Both the first and second gestures are recognized. Semantic content can be assigned to the existence of and various details regarding the interruption and gestures involved.

Abstract: A method for classification recognition of gestures and gesture primitives in a touch-based user interface. In an implementation the method comprises receiving tactile image data responsive to data generated from user touch of a user touch interface comprising a sensor array. The tactile image data is processed to create a plurality of numerical values responsive to data generated from the user touch interface. These numerical values are applied to a principle component analysis operation to produce a reduced-dimensionality data vector which is applied to a classifier having a plurality of classifier outputs interpretable as probabilities. The classifier outputs provide likelihoods that an execution gesture is from a collection of pre-defined gestures, and a decision test is used to produce a decision output indicating a gesture outcome useful in user interface applications.

Abstract: This invention relates to signal space architectures for generalized gesture capture. Embodiments of the invention includes a gesture-primitive approach involving families of “gesteme” from which gestures can be constructed, recognized, and modulated via prosody operations. Gestemes can be associated with signals in a signal space. Prosody operations can include temporal execution modulation, shape modulation, and modulations of other aspects of gestures and gestemes. The approaches can be used for advanced touch user interfaces such as High-Dimensional Touch Pad (HDTP) in touchpad and touchscreen forms, video camera hand-gesture user interfaces, eye-tracking user interfaces, etc.

Abstract: The invention provides 3D touch gesture recognition on touch surfaces incorporating finger posture detection and includes a touch user interface device in communication with a processing device. The interface device includes a sensor array for sensing spatial information of one or more regions of contact and provides finger contact information in the form of a stream of frame data. A frame is read from the sensor array, subjected to thresholding, normalization, and feature extraction operations to produce a features vector. A multi-dimensional gesture space is constructed having desired set of features, each represented by a space dimension. A gesture trajectory is a sequence of transitions between pre-calculated clusters, and when a specific gesture trajectory is detected, a control signal is generated.

Abstract: A method for selecting an entry from a list of entries on an electronic device is described. The method includes a displaying at least a portion of a list of entries along with a plurality of distinct, non-overlapping groups of text characters, the groups displayed in a geometric pattern. Additional retrievable data can be associated with each entry and retrieved when that entry is selected. A group selection event selects a particular group of characters. A matching operation compares text characters of the selected group with those of each entry in the list. A smaller, modified list is created comprising entries comprising at least one text character of the selected group. At least a portion of the modified list is displayed, highlighting text characters matching text characters of the selected group. Group selection can result from user operation of geometrically associated keys, a touch sensitive display, or other directional input device.

Abstract: A system (and method) for selecting an entry from a list of entries on an electronic device is disclosed. The system is configured to display a plurality of banks to a user and to receive a bank selection event from the user for selecting a bank containing a set of characters. The user creates a bank selection event through an input device such as a navigation device or touch screen. The set of characters is appended to a prefix that is used to determine a current result list containing entries that match the prefix. The list of entries is reduced to the current result list and displayed to the user with the portions of the entries matching the prefix highlighted. After the list of entries is reduced to a desired size, the user enters a scrolling mode where the user scrolls through the list of entries and selects an entry.
