1. A method, comprising: detecting a presence of a first stationary conductive object at a sensing device; detecting a presence of a second conductive object at the sensing device while the first conductive object is present at the sensing device; detecting a tap of the second conductive object while the first stationary conductive object is present at the sensing device, wherein a time duration of the tap is less than a threshold time; and recognizing a gesture based on the detected presence of the first stationary conductive object, the detected tap of the second conductive object, and a direction, along an axis, of a difference between a position of the first stationary conductive object and a position of the second conductive object, wherein recognizing the gesture comprises: recognizing a tap gesture of the second conductive object; determining a first position of the second conductive object; and recognizing a scroll gesture based on the presence of a first conductive object, the first position and the tap gesture.
