Abstract

In this paper, we present the description of an animation solver that allows the automatic moving of the different parts of a signing avatar body. The objective is to obtain a realistic animation of the virtual character that enables deaf person to visualize realistic gestures. Our approach is based on a thorough study of sign language and gestures classification. We identified the main constraints required for automatic generation of postures in sign language, and we developed a graphical interface in order to facilitate editing. This interface allows, in particular, the selection of the sign components and the rendering of the choice made on the avatar postures. The challenge of this project is to find a good compromise between computational time and realistic representation that should be closer to real-time generation signs.
