A Novel Approach to Communicate with Deaf Dumb and Blind Person
Abstract
In day to day life communication is major issue for deaf, dumb people and for Blind person it is difficult to take notes of particular things. So, for removing the barrier of communication a glove is designed for mute people with preloaded messages and a Braille embosser for Blind person to read notes in Braille language.
The main objective of this paper is to design a portable and reasonably sized Device that is easy to use. The design for this Device was made keeping in mind all different kind of disabilities. This paper is valuable to a disable person who is having difficulty in communicating with others. The hardware implemented in this paper can be used remotely to give notes to blind by imprinting on Braille Embosser. To implement this paper the main components are PIC18F886, APR33A3, Bluetooth Transceiver HC-05, Flex Sensor, Servo motors SG-90.

Introduction
In real word, there are many people who are deaf and dumb cannot communicate easily. Hence in this paper a glove is designed using flex sensor to communicate between Dumb and normal people and assigning particular message for each gesture .The gestures created by the glove will be sent to normal person’s phone and will also be displayed on LCD. In this paper a Braille Embosser is designed to communicate with blind person having servomotors to imprint Braille characters with the advancement in the technology, there have been many innovations in regards with this disabled people but person with moderate income would not afford it. So the first and the foremost need of a society is to develop a system through which a person with disabilities can live a life that a normal person does.
Disabilities like blind, deaf, dumb are more of serious concern. Science and Technology have made Human life addictive to comfort but still there exists an underprivileged group of people who are fighting for finding a innovative way that can make the process of communication easier for them. According to the World Health Organization, about 285 million people in the world are blind, 300 million are deaf and 1 million are dumb. In day to day life communication is major issue for deaf, dumb, blind people. This paper “A Novel Approach to Communicate with Deaf, Dumb and Blind Person” removes the barrier of communication between them and normal person.
Conclusion
After working on this noble idea this paper successfully build a device to remove the barrier of communication between deaf, dumb and blind person and a disable person .People can use Bluetooth device for the communication whose range is descent for now i.e. 30 meters. Hence this device can work wirelessly used for around 30 meters. Simulation result &hardware implemented shown in figure 5 & 6 respectively.As per the design and application of this device, if properly manufactured in small size and in large amount this device can be manufactured at a very low price with high usability .This is a very noble approach to communicate bidirectionally between normal and disable person. This is very useful for the blind person as with the help of this device he can read anything which is written in normal English language and can be imprinted on the Braille embosser. People can also communicate wirelessly using this Braille embosser to blind person .Flex sensor results can also be displayed on mobile screen wirelessly using Bluetooth , in future WIFI technology will be use to increase the range of the device.
