Sign Language HPSG

We present an overview of some relevant aspects of sign language synthesis in the ViSiCAST project, which might serve as a possible basis for the Dicta-Sign project. Dicta-Sign is a 3-year EU-funded project, that undertakes parallel corpus collection in different Sign Languages (SLs) and fundamental research and development of sign recognition and generation techniques in order to open up new potential applications for sign language users. One of the aims in Dicta-Sign is to find a model that is suitable for both recognition and generation. In this paper we revisit the main aspects of the synthesis techniques implemented in ALE Prolog using a sign language specific HPSG with the view for future changes needed.
