Abstract - Communication is the driving force of mankind. In this modern era, Science and technology have made the human world so easy but still some physically and visually challenged people suffer from communication with others. It may be by birth or caused by any kind of accident. After losing communication, these people cannot do the normal functions or normal life. Majorly they cannot communicate with others. Various languages specifying sign language, Braille scripts, Morse codes were proposed by researchers to provide a specific communication medium. Even after such inventions, there is a clear visible gap between the communication of the normal person and a specially challenged person and communication between two specifically challengedpeople.

Key Words: blind, deaf, dumb, issues, text, speech, vibrator

1. INTRODUCTION

According to ministry of statistics and program implementation 2.68 crore of the current Indian populationisspeciallychallenged,ofwhich44%consistof people who suffer from neither hearing speech or visual impairment. We're going to propose a new system prototype in this project called communication among blind, deaf, and dumb persons. This will aid those with disabilities in overcoming their communication barriers with both those without disabilities and those who have disabilities.

Blind individuals will use the speakers to communicate, whilethedeafanddumbwillbeabletoseethroughitand respond by tapping the sensor. All of these have been developed as applications so that people with impairmentscanusethemwithcomfort.Amodelhasbeen developed which is focused on multi model approach can beabletoconvertspeechtovisualcontextsandvibrations andsimilarlythecontextsandvibrationscanbeconverted tospeech.

1.1 Binary Code

I. Binary code represents text, computer processor instructionsoranyotherdatausingatwo-symbol system. The two-symbol system used is often "0"

and "1" representing "off" or "on" respectively frombinarynumbersystem.

II. In today's digital world, binary code is one of the mostimportantnumbersystems

III. Our goal for this project is to teach disabled people about binary number system and how it applies to the technologies. In this we convert 26 lettersofEnglishalphabetto5-bitbinarycode

2. LITERATURE REVIEW

[1] A two-way communication system with Morse code medium for people with multiple disabilities:

Inthisresearch,awearablesystemwithawidenetworkof Morse code recognition and transmission is proposed. It can be used to establish short- and long-distance communication between a person with a disability and a healthy person, as well as communication within themselves. Four user-selectable operating modes, 1. Morse to Speech (MTS), 2. Speech to Morse (STM), 3. Distance Morse to Text (DMTT)4. Distance Text to Morse are used by the system (DTTM). Depending on the application, the user can access each mode by making particulargestures.Basedonthemachinelearningmodel, the gesture is identified. The four proposed userselectablemodesandthesensor-infusedwearablesystem, which are the paper's key contributions, are meant to address the majority of communication issues faced by people with disabilities. The final section of the article details how each proposed mode operates and how the usercanaccessthem.

[2] A Contactless Morse Code Text Input System Using Ambient Wi-Fi Signal:

Patients with motor neuron disease (MND) have trouble moving their hands or arms, and even their speech function is significantly compromised, making it difficult forthemtocommunicatewithotherpeopleandtheseIoT gadgets. Wi Morse isa single-fingertext entrymethodfor MND patients that uses the Morse code. Wi Morse can identify finger input of letters, numbers, phrases, and sentences accurately without affixing any sensor to the finger by merging Morse code with contactless Wi-Fi

sensing. First, we suggest using the ratio of the CSI between two antennas at the same Wi-Fi receiver to capture the very slight signal change caused by a finger gesture. This efficiently removes signal noise because the two antennas on the same hardware share very comparable hardware noise Second, in order to address the location dependency problem, we investigate the underlying cause and provide a signal transformation mechanism that rotates the original signal space by automatically choosing the best transformation vector in accordancewiththeinitialinputposition.WiMorsecanbe strong to input, position, environment changes, and user diversityasaresult.

In order to improve the SNR, which can detect delicate finger movements that are normally impossible when using a single antenna, we suggest employing the ratio of theCSIbetweentwoantennasonthesameWi-Ficard.We empirically investigate, validate, and use the CSI ratio's characteristics to inform the Morse code sensor design. Thefindingsoftheextensiveexperimentsindicatethatthe transformation process that has been suggested can greatly improve recognition accuracy from 48% to above 95%.Theaverage textinputspeedcan equal other Morse code-based input systems at 2.94 words per minute (WPM).

[4] Finger Braille: Tactile Communication for Differently Abled:

Modern life would not be the same without mobile devices. Many of us require the ability to call or send a message from any location at any time. Compared to the rest of us, visually challenged folks find it challenging to usetheseapplications.Braillewasfirstdevelopedin1824 to provide blind people with access to information when there was none. The system receives input in the Braille language.LouiseBraillecreatedBraille,alanguageforthe blind that made it easier for them to read text (18091852). Braille is a system that allows for the tactile perception of information. Six raised dots make up the Brailleinitscurrentdesign.Thispaper'sgoalistoprovide an illustration of a wearable device made with forcesensitive sensors. Six dots are used in the creation of the Braille text. It simulates the six-finger virtual keyboard needed for Braille typing. We shall type in this document usingthethreefingersonourhands,whichareourindex, middle, and ring fingers. In this study, the android device is receiving input through the Braille language medium.

[5] Braille Character Recognition Based on Neural Networks:

The most widely used system for tactile communication between visually impaired and sighted persons is Braille. The two primary steps of optical Braille character recognition (OBCR) are the recognition of the Braille cells andBraillecellstranscriptionintotheappropriatenatural language letters. They can feel raised dots on the tips of their fingers on a Braille page because it indicates the binary tactile code system used by blind and visually impairedpeopleinsteadoftraditionalprintedreadingand writingmethods.EachBraillecell,whichismadeupofsix raised dots arranged in three rows and two columns, represents a letter of the alphabet. In this report, an artificial neural network (ANN) technique for optical Braille character recognition was explored. Braille is the most widely used method of communication between Artificial Neural Networks, a computer approach created tosimulatehowthehumanbrainperformsvariousjobs.

The OBCR system can translate Braille characters into their equivalents in natural English, bridging the gap between blind, visually challenged, and sighted persons. Anyone who works with blind individuals who doesn't know the Braille scripting language can benefit from it. The project's main drawback is that neural networks, which are made up of numerous interconnected processing nodes and are designed after the brain. Each node computes using its weight parameters and backpropagates them to make adjustments. Due to its numerous parameters, ANN also requires more extensivetraining datasets. These factors make ANN computationallyintensive.

3. PROPOSED WORK

In this project we are proposed a system for multi disabilitypeoplelikeblinddeafanddumbpeople.

Blind module: As a replacement for the braille system that was once used to communicate with the blind, we now employ the Voice Controller System. In this, blind persons can communicate with others by speaking throughthevoicecontroller.

Deaf module: Using a vibrator to receive messages and a keyboardtotypemessagestoothers,wecanconnectwith deafpersonsusingthismodule.Itisshownonthesystems ofotherpeople.

Dumb module: Withthehelpofthisdumbmodule,users can send the messages by text and can receive the messagesthroughvoiceandintextualform.

cannotseeandcannot navigatearound places,mainlythe communication between people who are blind and communication with everyone is difficult. Communication of a deaf people is also difficult. Being a deaf limits the ability to receive and process the information. Dumb people communicate with others using their body language merely; especially their hand gestures. This communication mode is said to be complex. This paper aims to minimize the communication gap between the deaf, dumb and blind community and the normal world andhelpthem toleada preferredlife.
