Toward a Motor Theory of Sign Language Perception
Researches on signed languages still strongly dissociate lin- guistic issues
related on phonological and phonetic aspects, and gesture studies for
recognition and synthesis purposes. This paper focuses on the imbrication of
motion and meaning for the analysis, synthesis and evaluation of sign language
gestures. We discuss the relevance and interest of a motor theory of perception
in sign language communication. According to this theory, we consider that
linguistic knowledge is mapped on sensory-motor processes, and propose a
methodology based on the principle of a synthesis-by-analysis approach, guided
by an evaluation process that aims to validate some hypothesis and concepts of
this theory. Examples from existing studies illustrate the di erent concepts
and provide avenues for future work.Comment: 12 pages Partiellement financ\'e par le projet ANR SignCo

Providing signed content on the Internet by synthesized animation
Written information is often of limited accessibility to deaf people who use sign language. The eSign project was undertaken as a response to the need for technologies enabling efficient production and distribution over the Internet of sign language content. By using an avatar-independent scripting notation for signing gestures and a client-side web browser plug-in to translate this notation into motion data for an avatar, we achieve highly efficient delivery of signing, while avoiding the inflexibility of video or motion capture. Tests with members of the deaf community have indicated that the method can provide an acceptable quality of signing
