There have been continuous research and development in the area of human-computer-interaction to find an easier way of interacting with the computer. One among such ways which has been of keen interest is hand gesture based interaction. Hand gesture based interaction provides a more natural and intuitive way of communicating between man and machines. This kind of interaction has applications in numerous fields like computer gaming, health care, virtual reality and many more.
