METHOD AND APPARATUS TO DETERMINE DIRECTION OF MOTION IN A SENSOR ARRAY OF A TOUCH SENSING DEVICE

Direction of motion in a sensor array of a touch sensing device may be determined using a rule-based algorithm. A presence of a conductive object on a sensing device may be detected. First, second, and third locations of the detected presence of the conductive object may be determined. The first location may be compared with the second location using the rule-based algorithm, and a first direction of motion of the conductive object may be recognized based on the comparison. The second location may be compared with the third location using the rule-based algorithm, and the same first direction of motion of the conductive object may be recognized based on the comparison.
