Overview of Hand Sign Recognition System

Abstract

Abstract: Hand gesture is one of the methods used in sign language for non-verbal communication. It is most commonly used by deaf & dumb people who have hearing or speech problems to communicate among themselves or with normal people. Various sign language systems have been developed by many makers around the world but they are neither flexible nor cost-effective for the end users. Hence, it is software that presents a system prototype that can automatically recognize sign language to help deaf and dumb people communicate more effectively with each other or normal people. Dumb people are usually deprived of normal communication with other people in society, also normal people find it difficult to understand and communicate with them. These people have to rely on an interpreter or some sort of visual communication. An interpreter won’t be always available and visual communication is mostly difficult to understand. Sign Language is the primary means of communication in the deaf and dumb community. As a normal person is unaware of the grammar or meaning of various gestures that are part of sign language, it is primarily limited to their families and/or deaf and dumb community
