A Survey on Sign Language ATM For The Blind

The blind population often face difficulties in accessing ATM machines to withdraw money, which forces them to visit the bank. This makes them lose their time, thus causing them inconvenience. In order to overcome this issue, most of the ATM keypads offer Braille embossed keys with an intention to guide a blind individual to access the system. Though proven to be useful, the blind people with no knowledge of Braille fail to access these systems independently. Thus, to overcome this issue, other ways to access the ATM machines must be explored. One way out is to utilise Sign Language gestures to interact with the system in an environment that is secure. The survey on different methods proposed to recognise the sign language is conducted in this paper.
