Real-time Facial Expressions in the Auslan Tuition System

Facial expressions are an integral part of Australian Sign Language (Auslan). This paper presents the implementation and integration of facial expression into the Auslan Tuition System. To incorporate this feature, we use a 3D mesh and animation of an avatar to dynamically display the Auslan signs. Vertex blending is used to improve the aesthetic quality of this model. The mesh provides a basis for the three most integral components of expression, namely emotion, head movements, and facial expression modifiers. These three components comprise the expressions that can be displayed and controlled in the Auslan Tuition System.
