A Review on Hand Gesture and Sign Language Techniques for Hearing Impaired Person

Abstract

AbstractSign language has been used by deaf communities for over three centuries. It serves as a platform for messaging and communicating. New sign languages are emerging in deaf communities all over the world. Movement and orientation of hands, arms body and facial expression can be used to represent one’s thought in sign languages. However, only a small percentage of public is aware of sign language. As a result, those who use sign language for everyday communication may have difficulty in communicating with normal people. Hearing aid devices have been introduced as a consequence of remarkable technology advancements to assist the hearing-impaired community in communicating with others. Hearing aid devices also would help individuals who have not entirely lost their hearing loss, while others who have hearing impairments will have to rely on sign language to communicate with one another. This paper will discuss review on hand gesture studies in providing sign language used in the hand gesture and sign language recognition process. It is hoped that this study may provide readers with a direction on the field of gesture and sign language recognition for further future work with regards to hearing impaired subjects.KeywordsHand gestureHearing impairedSign languageRecognition techniquesSmart health
