An Investigation and Observational Remarks on Conventional Sign Language Recognition

Abstract

In today’s world, communication of speech and hearing impaired person has been facilitated with different technologies. In the world, there are about 300 million people are deaf, 285 million are blind and 1 million are dumb, as per the World Health Organization. Sign language is a tool to communicate with speech and hearing impaired people. Recognition of sign language is a challenge for researchers from many years that have to be implemented as a system for various sign languages. Each system has its own limitations and difficult to be used commercially. Researchers have done their research in various ways to simplify the recognizing of sign languages with limited database. Researchers are trying to do research with their own large database. Through this paper, we review the different sign language recognition approaches and try to find the best method that has been used. This helps the researchers to retrieve more information to develop the sign language recognition systems using current and advanced technologies in future.
