Abstract:
A system and method for close range object tracking are described. Close range depth images of a user's hands and fingers or other objects are acquired using a depth sensor. Using depth image data obtained from the depth sensor, movements of the user's hands and fingers or other objects are identified and tracked, thus permitting the user to interact with an object displayed on a screen, by using the positions and movements of his hands and fingers or other objects.

Claim (Index 22):
A method for operating a user interface comprising:\n acquiring depth images of a user's hand with a depth sensor; constructing a model of the user's hand based on the acquired depth images; identifying, from the acquired depth images, movement of fingers of the user's hand based on the constructed model of the user's hand; tracking the movement of fingers of the user's hand using 3D data; projecting, using the 3D data, the user's hand on a screen as a first object performing gestures corresponding to the movement of fingers of the user's hand; as the first object interacts with separate objects on the screen, detecting fingers associated with the gestures, each finger associated with a different function, and modifying a display on the screen in response to performing one or more functions associated with one or more fingers detected as part of the gestures.
