A Sign Language Based ATM Accessing For Blind

The Blind people often have difficulty accessing ATM machines to withdraw money and have to go to the bank. It wastes their time, which makes them uncomfortable. To overcome this problem, most ATM keypads provide Braille embossed keys with the intention of guiding a blind person to access the system. Although useful, Braille unknown blind people fail to access these systems independently. Therefore, to overcome this problem, other ways to access ATM machines should be explored. Sign language is a way of using gestures to communicate with a system in a secure environment. This paper surveys the various methods proposed for sign language recognition.
