Patent ID: 8390577

Claim:
A computer implemented multi-touch (MT) gesture recognition (GR) method comprising the steps of: acquiring (1), at a processor, input data from a multi-touch input device; filtering, by the processor, input data and calculating (2) meaningful features for gesture recognition; performing, by the processor, a continuous recognition (3) of multi-touch gestures that allows users to start interacting with one multi-gesture and subsequently perform any other multi-touch gestures, if they want it, without needing to lift all their fingers off the multi-touch input device between each multi-touch gesture; performing, by the processor, at least one action (4.a, 4.b) during the user interaction sequence when a subset of input data is classified as a gesture; wherein said filtering input data step comprises a spatial segmentation method defined by the steps of: finding the underneath application for each contact point (2.A), associating (2.B) each contact points within an application to a user interface element of this application, and reducing the gesture recognition to a small set of gestures which are expected for this user interface element.
