Signing Avatar

A 3D computer-generated character that produces sign language through animated hand movements, facial expressions, and body posture. Signing avatars are used in educational contexts to deliver accessible sign language instruction, provide real-time multi-angle content, and offer a game-like learning experience. They can serve as model signers (pre-programmed movements) or mirror user movements in real-time through motion tracking. Research emphasizes that avatar effectiveness depends on movement accuracy and naturalness, particularly for subtle non-manual signs.
