Abstract

This paper addresses the identification and representation of the variations induced by style for the synthesis of realistic and convincing expressive sign language gesture sequences. A qualitative and quantitative comparison of styled gesture sequences is made. This comparison leads to the identification of temporal, spatial, and stuctural processes that are described in a theoritical model of sign language phonology. Insights raised by this study are then considered in the more general framework of gesture synthesis in order to enhance existing gesture specification systems.
