Several French national projects have been achieved last years, allowing linguist and computer scientists working on French Sign Language (FSL) to establish a permanent collaboration. During these projects, several video FSL corpora have been realised. One of the research orientations induced by these projects relates to multidisciplinary annotation. From the computer scientist s side, the aim is to develop an annotation software integrating different kind of tools based on image processing and 3d modelling that will be used to automatically annotate both lexical and syntactic information. This article presents several of these components. A first version of the annotation software integrating these components is under development.
