Abstract

The chapter focuses on signing avatars and their potential to improve deaf education. In sections 1 and 2, the authors give an overview of what signing avatars are and the benefits of using animated characters for deaf education. In section 3, they explain how signing avatars are created. In particular, in subsection 3.1, they describe different types of 3D models and skeletal deformation systems, and in subsection 3.2 the authors discuss a variety of methods used to animate manual and non-manual signs. In section 4 they report the state of the art in signing avatars’ research and development and we discuss existing limitations and future trends. Section 5 includes a case study on the production of the signing avatars for SMILE™ and Mathsigner™ Conclusive remarks are presented in section 6.
