Hand gesture recognition system received great attention in the recent few years because of its manifoldness applications and the ability to interact with machine efficiently through human computer interaction. Recognition of Gestures helps and enables the humans to interact and communicate with computers and IT devices in a natural way. Hand Gesture can be termed as interactive process of interaction without physical connectivity. Gesture recognition helps in the environment known to be HMI (humans communication with the machine and interact) and that does not include touch of mechanical devices. Techniques such as Image process are at prime and sometimes use of hard ware devices become redundant as moving towards hand gesture recognition.
