Interactive System Based on Hand Tracking : AirGrip

This paper proposes a method to control an object on a screen by extracting information about a hand with a depth camera. The proposed method employs an appropriate rectangular region, then extracts the hand by setting the arm as a certain size through vector information. The method employs a convex hull to set a reference coordinate of the hand within the coordinate. The object on the screen is moved or scaled by verifying whether the thumb and index finger are stuck together or not through the extraction of the outline of the hand. The location of the hand is represented through a library capable of implementing 3D. An experiment was conducted with the proposed method and verified the operation of the command on the object.
