Introduction SIGN CHAT is an Android Application for deaf people
to communicate with normal people.
The Sign Languages are generally used by the deaf people in their conversation.
Initially, the Sign language is typed by the deaf person on one end of communication side and which is later converted into text on other end of communication side .
The Text-to- Sign and Sign-to- Text technology are implemented.
Problem DescriptionIn the current scenario there is no system which
enables the communication between specially abled people in existence.
We need a system that can be useful for every kind of users and not only for normal people.
The project is intended to create a mobile chat application than can be used by both specially abled people as well as normal peoples .
Sign Language InterpreterSign language interpreter is responsible for helping deaf or
hearing impaired individuals understand what is being said in a variety of situations.
An interpreter must understand the subject matter so he or she can accurately translate what is being texted into sign language .
Whenever an audience will be in need of sign language interpretation, a sign language interpreter is needed.
By using this application deaf person can easily interact with normal person anywhere, and he can also use this application for mobile sign translation and can communicate in daily activates.
Features Does not require large amount of storage The sign words are signed in the same order as letters appear in
English alphabets. It operates as an interpreter and translator, facilitating and
mediating communication between Deaf, Hard of Hearing and Hearing people
Accurate and appropriate transfer of a message from a source
language into a target language based on their style and culture Helps learn the culture and history of Deaf people to better
understand the communication between Deaf and Hearing individuals.
Proposed systemWe propose a mobile app for the deaf person to easily
interact with normal person from any where.
This system also supports automatic translation, chat facility and text-to- sign and sign-to- text transmission .
The app can be used to communicate between specially abled people, and between specially abled people and normal people .
The main part of this system which is communication between deaf is implemented using ASL.
All letters are signed using only the right hand which is raise with the palm facing the viewer.
Sign English[SE] is a reasonable manual parallel to English.
The idea behind SE and other signing system parallel to English is the deaf will learn English better if they are exposed .
SE uses two kinds of gesture: Sign Words, and Sign Markers. This facilitates the deaf to easily interact with normal person.

Text-to-Symbol Conversion
This module performs the text to symbol conversion.
Using this module a deaf person can easily understand what the text is all about.
This person using this module on this or her mobile will be able to identify the text via the symbols stored in the database
Symbol Database
Symbol database is where the symbols and their corresponding texts are stored in the system.
This module will store symbols regarding single characters as well words.
This can be used to understand the information being sent and received.
Symbol-to-Text Conversion
This module performs the symbol to text conversion.
Using this module a deaf person can easily type a response in symbols there by sending texts as response to the text received.
ServerIt maintains every sign patterns and its
corresponding textual information.
Client enter symbol or text.
Proper conversion from text to sign for deaf people and sign to text for other clients are made.

E-R Diagram
ConclusionThis research has designed a Chat
application for deaf people to communicate with normal people.
The system is implemented with high degree of accuracy and user friendliness.
The accessing of the system is very simple. Since this is a user friendly software, any
user who does not have any idea about this system can handle the software very easily.
The system has been factored into different modules to make system adapt to the further changes.
Scope For Future EnhancementIn future since each and every application should
expand and it should provide a way for updating the system has been developed.
All modules in the system is being developed carefully such that the future enhancement does not affect the basic performance of the system.
In future we can add text to speech and speech to text conversion system to the application.
We can add more chat symbols according to the user’s local language other than American sign language (ASL).
Thank you…
