Abstract :- Today the main problem faced by the deaf
and dumb people is the communication part, to convey their thought with other deaf and dumb people and with other normal people.Normal people can absorb new information and knowledge through the daily noises, conversations and language that is spoken around them. Deaf and hard-ofhearing people do not have that luxury. This system will help those people by providing a medium to communicate. It is implemented using devices like flex sensors, and microcontroller. KEYWORDS: Gesture, flex sensor, microcontroller.
•
As per shown in image every word/character has predefined pattern of finger and palm combination.
• This system is to identify this pattern or combinations electronically.
1. INTRODUCTION People who are deaf and dumb often tend to feel uncomfortable around other people, when drawing attention to their hearing problem. Those people wants to be like their friends with good hearing, so this drives a thought in them to mainly keep to themselves and to not take part in activities with those normal people. Sign languages are used by mute people as a medium of communication. Sign languages are used to convey thoughts with symbols, and objects etc. They also convey combination of words and symbols(i.e. gestures). Gestures are different patterns made by the curls and bends of the fingers. Gestures are the best medium for their communication .

In this system glove is implemented to capture the hand gestures of a user. The gloves are having flex sensors along the length of each fingers and the thumbs. The flex sensors output a stream of data that varies with degree of bend. The analog outputs from the sensors are then fed to microcontroller. It processes the signals and perform analog to digital signal conversion. The gesture is recognized and the corresponding text information is identified. The user need to know the signs of particular alphabets and he need to stay with the sign for two seconds. There are no limitations for signs it is hard to
