German Sign Language

The sign language used by the deaf community in Germany, recognised as an independent natural language with its own grammar, syntax, and vocabulary distinct from spoken German. Like other sign languages worldwide, German Sign Language is a visual-spatial language that uses handshapes, facial expressions, body movements, and spatial relationships to convey meaning. DGS is one of many national sign languages, each with its own linguistic structure — sign languages are not universal, and a GSL user cannot automatically understand American Sign Language or British Sign Language. Research and technology development for GSL users, such as avatar-based translation systems, must account for GSL's specific linguistic properties.
