A review on vision based American sign language recognition, its techniques, and outcomes

American Sign Language Recognition (ASLR) system is a process where the computer understands the gestures of American Sign Language (ASL) automatically and converts them into their equivalent human / machine readable text. Several researchers have presented various vision based techniques to recognize static and dynamic gesture recognition of ASL. In this paper an effort has been made to highlight the various works and a comparative study of those works carried out by the researchers in recognizing ASL.
