A Robotic Hand: Controlled With Vision Based Hand Gesture Recognition System

Human-robot interaction (HRI) has become an important topic in today’s robotic world, especially in assistive robotics. Now pen, mouse, keyboard etc. are not sufficient due to the limitations of these devices for taking command. Human now wants direct use of hands as an input device for getting more natural human-robot interactions (HRI). Vision based hand recognition system has come with a solution for these type of demands of human. In this system, human need not to operate any kind of devices, instead a camera is used for recording the movements of hands and these recorded data are used as input for performing any kind of gesture control. The elderly people, patients and disabled can be benefitted from these kind of gesture control. Besides it can be used in extreme environments where human can’t go directly. Here, a vision based hand gesture system for controlling robotic hand has been developed. The main intension here, is to implement a vision based gesture recognition system that recognizes data gathered from hand movements through a camera.
