Sign Language Interpreter

Abstract

There are five human senses connecting each of us with the surrounding world. Deaf and hard of hearing people are missing one of these senses. Their communication is strongly affected, because most of them are not able to communicate verbally. In this article a graphic system for the computer visualisation of the sign language (the means of communication between deaf people based on hand movements) will be described. The system visualises an animated human model in real time and is able to translate written text into the sign language (with the limitations of the dictionary). In the following paragraphs an introduction to the sign language will be presented as well as an explanation of the geometric model of human being, controlling of animation and real time visualisation using OpenGL API.
