Methods to describe and recognize sign language based on gesture components represented by symbols and numerical values

Abstract

Sign-language gestures inflect according to the context. To recognize such sign language properly, the structure of sign language must be made clear. It is well known that the structure of sign language is represented as a combination of gesture components. In this paper, methods for the description and recognition of sign-language gestures based on the gesture components are discussed. In these methods, which we have developed, a sign-language gesture is recognized by integrating the recognized gesture components according to the structure of the gesture. The results of an experiment on recognizing sign-language gestures are also examined and it is shown that the developed methods are effective.
