A Review Paper on Real Time Sign Language Detection for the Deaf and Dumb

Hand gesture is one of the styles used in sign language for non-verbal communication. It's most generally used by deaf & dumb people who have hearing or speech problems to communicate among themselves or with normal people. Plathora sign language systems had been developed by numerous makers around the world but they're neither flexible nor cost-effective for the end druggies. Hence, it's a software which presents a system prototype that's suitable to automatically recognize sign language to help deaf and dumb people to communicate more effectively with each other or normal people. Dumb people are generally deprived of normal communication with other people in the society, also normal people find it hard to understand and communicate with them. These people have to depend on an interpreter or on some kind of visual communication. An interpreter won’t be always available and visual communication is substantially delicate to understand. As a normal person is ignorant of the grammar or meaning of numerous gestures that are part of a sign language, it's primarily limited to their families and/ or deaf and dumb community
