Sign Language Interface

A computing interface that accepts input from, or presents output to, a user in a signed language such as American Sign Language (ASL) or British Sign Language (BSL), rather than assuming a spoken or written language. Sign-language interfaces span sign-language recognition (vision-based input), sign-language generation (animated avatars or recorded video output), sign-language dictionary search, and end-to-end applications such as voice assistants that accept ASL commands. Because signed languages are visual and lack a standard written form, sign-language interfaces cannot be built by simply swapping text strings; they require video or motion-capture I/O, appropriate linguistic modelling, and design choices grounded in Deaf cultural norms. Development of these interfaces is a multi-disciplinary effort spanning HCI, computer vision, NLP, linguistics, and Deaf studies.
