  • Method to parameterize and recognize circular gestures on touch sensitive surfaces
    Patent number: 8754858
    Abstract: A method to parameterize and recognize circular gestures on touch sensitive surfaces includes dividing the touch sensitive surface into four quadrants, detecting a transition from a first quadrant into a second quadrant, time-stamping and tracking each detected quadrant transition, and computing the time between quadrant transitions so that the circular speed and direction of the circular gestures on the touch sensitive surface can be detected. The detected direction can be either a clockwise or a counter-clockwise direction.
