If useful printers are introduced, straightforward font sets and software drivers should allow dotsplus documents to be produced with common word processors or from such programs as TeX or SGML, both of which are accessible to blind users. Examples in this document were produced by a sighted person using Microsoft Word with special dotsplus fonts. Math equations are reproduced as enlarged images of the equation as printed for a sighted person. The plus, minus, and equals signs, parentheses, brackets, the division line in fractions, and the multitude of exotic symbols used in advanced science and math are all printed as raised images. Some symbols may be enlarged more than others or their shapes may be emphasized for clarity, but all are instantly recognizable by sighted mathematicians.
Braille is used only for alphabetic characters, numbers, and punctuation marks.
Text in a dotsplus document can be written in standard braille or dotsplus symbols. Dotsplus text may be preferable if the text contains many scientific symbols. In order to avoid ambiguity and to incorporate most of the characters used in elementary math into single braille cells, dotsplus braille is based on the 8-dot cell and does not use any dropped symbols. Dotsplus braille cells have been chosen to be as intuitively-related as possible to literary braille. The lower case alphabet is standard braille.
