Sutton SignWriting is the universal and complete solution for written sign language. It has been applied by a wide and deep international community of sign language users.
Sutton SignWriting is an international standard for writing sign languages by hand or with computers. From education to research, from entertainment to religion, SignWriting has proven useful because people are using it to write signed languages.
Formal SignWriting is one particular computerized design for Sutton SignWriting that envisions a sign as a two part word. Each word is written as a string of characters that can be recognized and processed by regular expressions. The design has been optimized for display, searching, sorting, text flow, and other character processing.
Where as American Sign Language is a natural language, Formal SignWriting is a formal language. A formal language is useful in mathematics, computer science, and linguistics.
Signs are written as SignWriting words with mathamatical names of ASCII characters from the set: ABLMRS0123456789xabcdef. Stable since January 2012.
Signs are written as SignWriting words with an experimental Unicode character design. This character set overwrites the Sutton SignWriting Block (U+1D800 - U+1D9FF) and uses Plane 4 for the Sutton SignWriting symbols.
The Sutton SignWriting TrueType fonts are available for download and installation.
There are two fonts for the Sutton SignWriting symbols that are used in SVG: the Sutton SignWriting Line font as the positive space of the symbol glyphs on Unicode plane 15 and the Sutton SignWriting Fill font as the negative space of the symbol glyphs on Unicode plane 16. These glyphs descend below the baseline.
The Sutton SignWriting One-D font is production ready. It uses the SignWriting in Unicode (SWU) experimental characters to visualizes a sign as a 1-dimensional string of glyphs for structural markers, symbols, and numbers. These glyphs are centered above the baseline and are meant to be used in traditionally 1-dimensional situations.
The Sutton SignWriting Null font provides empty glyphs for invalid symbol codes on Plane 4 and Plane 15. The font is useful to normalize how browsers and software process invalid characters.
This library leverages the TrueType fonts without any additional requirements. Simply include the "SuttonSignWriting.js" script or the minified version "SuttonSignWriting.min.js" in any HTML page to access the function library. View the API Reference for example usage.
