Abstract: A method of matrix sensing using delay-based capacitance sensing, including using X-axis lines as active lines for capacitance measurements and using Y-axis lines as a disturbance to identify the location of a touch in a key matrix is disclosed. A sensing signal is applied to the X-axis lines, and a disturbance signal is applied to the Y-axis lines. If a location is touched, cross-capacitance is reduced, which is measured by sweeping data along the X-axis lines.

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.
