Method Detail

strokeCompleted

public RecognitionSet strokeCompleted(TimedStroke s)

Compute the ratio of the sum of the absolute values of the delta y's and the sum of the absolute values of the delta x's, the aspect ratio, and the number of corners. These are used to determine the scribble confidence value for the gesture.
