1. A method of navigating a multi-layer presentation tree using gestures of a hand, which is a control object in a three-dimensional (3D) sensor space, using a 3D sensor, the method including:
processing an output of a camera of the 3D sensor thereby sensing a movement of the hand in any direction in the 3D sensor space using a control plane that remains tangent to a surface of a palm of the hand or a surface of the back of the hand throughout the movement of the hand, the control plane being defined by a sensed orientation of the surface of the palm of the hand or the surface of the back of the hand, such that an orientation of the control plane adjusts according to the sensed orientation of the surface of the palm of the hand or the surface of the back of the hand; and
interpreting by a computing device a direction of the movement of the hand as scrolling through a particular level of the multi-layer presentation tree when a direction of the movement of the hand is more normal with respect to the surface of the tangent control plane than parallel with respect to the surface of the control plane.
