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. The arrangement can recognize single finger '6D' actions of roll, pitch, yaw, left-right, forward-back, and variations in applied pressure.
