Considerable effort has been put towards developing intelligent and natural interfaces between users and computer systems. This is done by means of a variety of modes of information (visual, audio, pen, etc.). The use of gestures as means to convey information is an important part of human communication. The automatic recognition of gestures enriches human - computer interaction by offering a natural and intuitive method of data input. This paper presents a new technique for hand gesture recognition, for the Human-Computer Interaction (HCI) based on shape analysis.
