Interaction between humans and computers is an area of research that comes into focus in the late 1980s. Human hand simulation is an issue that obtain remarkable research in the past but now from the previous few years’ computational abilities and camera performance are improved quickly. So that human hand simulation is not limited to paper or some digital surfaces, it is extended to the 3 dimensions [14]. Robotic arms are controlled by a controller in most of the systems. Atmega32 microcontroller processing unit has been used to interface the hand gesture input with the robotic arm. The robotic arm can move in 2D or 3D depending on the system design parameters [15] [16]. A GUI was designed and implemented to provide the process of generating hand signals and movement. Controlling the virtual hand, recording hand images, and creating hand gestures and animations were the major functions of this GUI [17]. This work was increased by producing a virtual environment. This is for the hand models and developing the effective operations in such a way that this GUI should play the basic role of an interactive interface between the virtual hand and its users and this type of interface consists of a hand simulation. Real-time hand gesture recognition is used to simulate human hand movement [18] [19]. They used the camera for capture the Images passing through the different phases. The first phase is the acquisition phase. The keyboard or any pointing device will be not accepted in this procedure, so they focused on smart interfaces. The basic idea was that time is expanding the installation in homes, play stations by capturing devices. They were very careful about the design of the processing system [20]. In computer games, hand gestures are used to control the movement and orientation of the game object. Hand gestures and robotic arms can be used in computers and games. In-play station, an eye toy camera is used which captures the hand gesture motion.
