THE HAND About nine million people in the world are considered to be deaf or dumb or both. Communications between deaf-dumb and a normal person have always been a challenging task. Generally dumb people use sign language for communication but they find difficulty in communicating with others who don’t understand sign language. This project aims to lower this barrier in communication. For this purpose, we have built a system that involves the following features:-
- Precise Sign-Language Recognition - Traditionally, flex sensors have been used so far to detect the hand movements. But it has many limitations. It is inaccurate and gives the same value no matter where the bent is. To solve this problem, we placed potentiometers at every joint of our hand so that we can detect exact hand movement and convert sign language in speech(or text). The person has to wear the glove and he can communicate using sign language. His phone needs to have the application that will generate corresponding speech that the other person can listen. There is an extra option in the application i.e if the sign language is not interpreted correctly, he or she can write whatever he wants to say in the application and that will be converted into speech.
- Alert for Deaf people - People who are deaf are generally precarious as they cannot hear fire alarms, car horns or any other
alerts. So for this, we have embedded a microphone sensor in the glove that will respond only if his name is called or there is
sudden change in the amplitude of sound. This is done using sound recognition API of Google. This way we can alert them about any
exigency around them.
NOVELTIES
- Perfect Assistant for Mute and Deaf person
- Much better Precision than flex sensor
- Alerts in case of any emergency
- Potentiometers are more economical than flex sensor
