Video-Based Sign Language Dictionary

A digital dictionary that allows users to look up sign language signs by submitting video of themselves performing the sign, rather than searching by text or linguistic features. These systems use sign language recognition technology to match the user's input against a database of known signs and return candidate matches. Video-based dictionaries address a fundamental gap in sign language learning tools: when learners encounter an unfamiliar sign in video content, they cannot easily look it up without knowing its English equivalent or linguistic properties like handshape and movement.
