Region Based Hand Gesture Recognition

Abstract

Evolution of user interfaces shapes the change in the human-computer interaction. With rapid emerge of threedimensional\n(3-D) applications, the need for a new type of interaction device arises since traditional devices such\nas mouse, keyboard, and joystick become inefficient for interaction within these virtual environments. A better\ninteraction in virtual environments requires a natural and suitable device. “Hand Gesture” concept in human\ncomputer interaction which has become popular in recent years can be used to develop such an interaction\ndevice. This study reports the development of a real-time, low cost, vision based hand gesture recognition\nsystem that works precisely on a relatively small restricted gesture space for single user robot control and\nhuman-computer interaction in such an environment that the lighting is relatively stable and the background is not complex.
