Sign Language Writing System

A system of symbols or characters designed to represent sign language in written form. Unlike spoken languages, which have well-established writing systems, sign languages generally lack a standard written form — meaning the approximately 70 million people worldwide who use sign language as their primary language cannot read or write in their native language. Existing approaches include character systems (like si5s, SignWriting, and ASL-phabet) that use sets of symbols to represent the linguistic components of signs — handshape, location, orientation, movement, and relative position — and transliterations that use spoken language words to approximate signs (like English gloss). A major challenge is that sign languages involve complex 3D movements that are difficult to capture with stationary 2D symbols, making these systems hard to learn. Animated character systems that leverage the animation capabilities of digital screens represent an emerging approach that can more iconically represent sign movements, potentially lowering the learning barrier and increasing adoption.
