Abstract :
In this world many people suffer from hearing
loss (deaf) and speech loss (dumb) that might have occurred
since birth or during their lifetime later. It is tedious for the
deaf & dumb people to talk with the ordinary people.
Peoples with sensory disabilities use their hands, fingers to
communicate and have access to the world. Sign language
is an expressive way for communication between normal
and deaf-dumb people and it is the symbolic representation
of words by using hands and fingers in different positions.
So ordinary people like us learn the sign language for the
purpose of communication. The sign language of deaf and
dumb is quite difficult to learn and it is not possible for
everybody to learn that language. So every person cannot
come and share their thoughts with these physically
impaired people. Sign language has the major limitation as
it is hard to understand by a normal people, only persons
those who know the sign language can able to communicate.
So it creates barrier in communication between the
impaired and normal people. Hence there must a midway
that would perform gesture detection, convert the gestures
into speech format (gesture to voice translating module) and
converts the speech of normal person to gesture (speech to
image translating module) and it is displayed on display. So,
the whole idea is to build an android application that
enables two way communications between deaf-mute
(speech-hearing impaired) person and a normal person. This
application uses certain image processing techniques.
