GESTURE VOCALIZER FOR DEAF AND DUMB

This paper provides information about the way in which the deaf and dumb people will communicate with each other through a device that will overcome most of the difficulties being found by deaf and dumb people. Deaf and dumb people use sign language for communication. That sign language cannot understand by normal people; so it creates barrier in communication between normal peoples and deaf and dumb peoples. Hence there must a midway that would convert this gestures into text and speech format, so normal people would understand it. In this paper, we used sensor based method. We use two sensors such as flex sensor and accelerometer which is mounted on gloves. Flex sensor is used to measure bending of fingers. Accelerometer is use to measure static and dynamic acceleration. In this paper we use AVR microcontroller and speech synthesizer. Data glove is gives most promising result with high accuracy and sensitivity.
