Interactive editing of utterances in French sign language dedicated to signing avatars (Édition interactive d'énoncés en langue des signes française dédiée aux avatars signeurs) [in French]

Interactive editing of utterances in French sign language dedicated to signing avatars Signing avatars dedicated to French Sign Language (LSF) are more and more used as a communication interface for the deaf community. One of the acceptation criteria of these avatars is the natural and realistic aspect of the constructed gestures. Consequently, gestures synthesis methods have been designed thanks to some corpus of captured and annotated motions, performed by a real signer. However, the enlarging of such a corpus, without requiring of some additional capture sessions, is a major issue. Furthermore, the automatic application of motion transformations (e.g. concatenation, blending, etc.) does not guarantee the semantic consistency of the resulting gesture. Another option is to insert the human operator in the utterance building loop. In this context, this paper provides a first interactive editing system of FSL gestures, based on captured motions and dedicated to signing avatars.
