Implementation of Human Hand Gesture Recognition System for External Control Network

Abstract Image processing plays a vital role in all the emerging domains. Cameras that are connected to computer systems record sequence of digital images of human hand in order to interpret human posture/gesture. Human hand posture/gesture recognition system has been utilized for providing virtual reality mechanism that is still an ongoing research in humancomputer interaction (HCI) community. Active HCI techniques like keyboard, mouse, joysticks etc., limit the speed of human interaction. In this paper we propose a novel system for detecting and recognizing human hand gesture. This system is more user-friendly and can be used even in robust environment. There are a lot of single hand gestures, the required gestures are first recorded in the form of images and during run time the gestures to be recognized are also taken in the form of image and are compared with the set of gestures previously recorded. If the images are matched with the stored one then corresponding output results will be generated. This results are interfaced with the hardware circuits with the help of an arduino board and interfaced with the boards or circuits between computer and then applied networks. Finally the hand gestures of a human are thereby implemented in controlling electronic Devices. This technique can be applied in controlling robots, machines and other electronic instruments.
