ABSTRACT
In our society we have people with disabilities. Even if the technology is developing day by day no significant developments are undertaken for the betterment of these people. Hand gesture recognition system is widely used technology for helping the handicapped people. We aim for developing an FPGA based hand gesture recognition system for establishing communication between the deaf and the dumb people. Gestures are considered as the most natural expressive way for communications between human and computers in virtual system. Hand gesture is a method of non-verbal Communication for human beings.

INTRODUCTION
Communications between deaf-mute and a normal person have always been a challenging task. About nine billion people in the world are deaf and dumb .The blind people can talk freely by means of normal language whereas the deaf-dumb have their own manual-visual language known as gestures. Human hand has remained a popular choice to convey information in situations where other forms like speech cannot be used. Gestures are powerful tools of communication among humans and are of particular interest to the deaf and dumb community. Bobick and Wilson have defined gestures as the motion of

CAMERA ( C3088)
The C3088 is a 1/4” color camera module with digital output. It uses Omni Vision‟s CMOS image sensor OV6620. Combining CMOS technology together with an easy to use digital interface makes C3088 a low cost solution for higher quality video image application. The digital video port supplies a continuous 8/16 bit-wide image data stream. All camera functions, such as exposure, gamma, gain, white balance, color matrix, windowing, are programmable through I2C interface. In combine with OV511+, USB controller chip, it will be easily form a USB camera for PC application. UART
