Hand gesture is an innovative technique of interaction between human and computer. Hand gesture recognition is a technology that is becoming increasingly relevant, given the recent growth and popularity of Virtual and Augmented Reality technologies. In this paper, we represent a novel approach for better human computer interaction (HCI) where we are using hand gesture recognition using real-time camera in order to overcome the drawbacks of existing methods and more user friendly. Our method is to use a camera and computer vision technology, such as image segmentation and gesture recognition, to control keyboard tasks and Hand motions are acquired using web camera based on color detection.
