Sign Language Interpreter for Deaf and Dumb People
Shweta S. Patil · International Journal for Research in Applied Science and Engineering Technology · 2019
For a person with disability (deaf and dumb) faces difficulty in communication with normal person. Because of this, a person who lacks in hearing (deaf) and speaking ability (dumb) is not able to communicate with normal person. This paper aims to lower this barrier in communication. Sign Language is used by deaf and dumb people for communication. A gesture in a sign language is a particular movement of the hands with a specific shape made out of them. A sign language usually provides sign for letters. Sensors in the glove pick up gestures and convert that to text data with the help of Analog to Digital convertor on arduino nano board. This converted text data will be sent wirelessly via WIFI module to a cell phone. The WIFI module transmits the gesture to a smartphone. Using Text to Speech software, incoming text message will be converted to voice. The arduino nano board will recognize the sign language for Alphabets and Numbers and it will display the message on computer and mobile. Sign Language interpreter system recognizes American Sign Language (ASL) alphabets, numbers in the form of letter, word or sentence based on sensor movement. A system is developed that can translate different signs using American SignLanguage to text as well as voice format.
