Sign Language Animator: A Platform for Multilingual Sign Language Synthesis

Sign Language serves as a vital communication mode for individuals facing challenges with spoken language. This paper outlines the development of a web-based Sign Language Animator aimed at bridging the communication gap between sign language and spoken language users. The application, accommodating 4,000 words across British Sign Language (BSL), Greek Sign Language (GSL), French Sign Language (FSL), and German Sign Language (DGS), leverages the Dicta-Sign project dataset. The dataset underwent conversion from the initial HamNoSys format to SiGML format through the HamNoSy2SiGML open-source tool, facilitating integration with the JASigning system. Our application supports both single-word and sentence animation, featuring zoom and rotation capabilities for enhanced 3D avatar visualization. In comparison to other avatar signing systems, our application stands out for its inclusivity, supporting four sign languages, and flexibility, empowering users to construct sentences without constraints.
