Abstract
An apparatus and method for recognizing a gesture based on detected presences of first and second conductive objects on a sensing device. The apparatus may include a sensing device having a plurality of sensor elements to detect presences of first and second conductive objects, and a processing device, coupled to the sensing device, to recognize a gesture based on the presences of the first and second conductive objects. The recognized gesture may be scroll gestures or click-and-drag gestures.
