Hand Gesture Recognition for Deaf and Dumb People Using GSM Module

The human being is blessed with ability to express his feelings and emotions through the words as well as sound. Its a god gift of us. But we have some less fortunes human living with us who are deprived of this valuable gift, such people are generally called as deaf and dumb people. so it has a serious problem as compared to blind people. For those people we proposed a new technique called artificial speaking mouth for deaf-dumb people. It will be very helpful to them for conveying their thoughts to others. This system is based on the motion sensor. According to deaf-dumb people, for every motion they have a meaning. In this system, first of all sensor sense the signal and given to the microcontroller ARM7-LPC2148 whereas all the data kept in the database. The microcontroller matches the motion of hand and with the database and message will be display on LCD as well as it produce the speech signal that is we will get the output through the speaker. The system is also included text to speech conversion, But in this system we can communicate with a long distance by using magic glove. In this, words are generated by a microcontroller and it will transmitted in the form of voice calls with the help of GSM modem to communicate with a long distance in a phone call
