Abstract

A sign language synthesis system converts previously noted signs into the computer animation. The animation is created using a specially designed 3D model of the human figure and algorithms transferring the sign to movements of the model. In principle the sign language contains both the non-manual component (shape and movement of hands) and the non-manual component (facial movements, etc.). Notation of the non-manual component was not yet sufficiently explored in terms of an automatic conversion to the animation. In the article we describe both notation methodology of the non-manual component and technical aspects for conversion of symbols to movements of the animation model. In addition an appropriate animation method for the 3D shape of face is assumed. The result is an extended notation supplementing notation of the manual component with the non-manual component. The extended notation preserves the feasibility of an automatic conversion and keeps the original level of generality. In connection with the methodology we present the notations of the basic types of non-manual components of the Czech sign language.
