GS8 Braille

The GS8 or Gardner-Salinas Braille code is a method of encoding mathematical and scientific notation linearly using eight-dot Braille cells for tactile reading by the visually impaired.

The code was developed as a replacement for Nemeth Braille by John Gardner, a physicist at Oregon State University, and Norberto Salinas, an Argentinian mathematician.

The GS8 Braille Code is an example of a compact human-readable markup language. Its syntax is based on the LaTeX system for scientific typesetting.
