For example, ⠌ dots 3-4 represents / in Braille ASCII, and this is the Braille slash, but ⠿ dots 1-2-3-4-5-6 represents =, and this is not the equals sign in Braille. Braille ASCII more closely corresponds to the Nemeth Braille Code for mathematics than it does to the English Literary Braille Code, as the Nemeth Braille code is what it was ...
A braille translator is a software program that translates electronic text (such as an MS-Word file) into braille and sends it to a braille peripheral, such as a braille embosser (which produces a hard copy of the newly created braille). Typically, each language needs its own braille translator.
RoboBraille is a web and email service capable of converting documents into a range of accessible formats including Braille, mp3, e-books and Daisy.The service can furthermore be used to convert otherwise inaccessible documents such as scanned images and pdf files into more accessible formats.
Tactile is a real-time text-to-braille translation device currently under development at the Massachusetts Institute of Technology. [1] It was conceived by a team of undergraduate students, competing as "Team 100% Enthusiasm", during a 15-hour MIT "hackathon". [2]
The braille package for LaTeX (and several printed publications such as the printed manual for the new international braille music code) show unpunched dots as very small dots (much smaller than the filled-in dots) rather than circles, and this tends to print better.
A braille embosser is an impact printer that renders text as tactile braille cells. Using braille translation software, a document or digital text can be embossed with relative ease. This makes braille production efficient and cost-effective. Braille translation software may be free and open-sourced or paid. [1]
In all braille systems, the braille pattern dots-0 is used to represent a space or the lack of content. [1] In particular some fonts display the character as a fixed-width blank. However, the Unicode standard explicitly states that it does not act as a space, [2] a statement added in response to a comment that it should be treated as a space. [3]
The system, however, was unable to handle deformities in the braille grid, so well-formed braille documents were required. [3] In 1999, a group at the Hong Kong Polytechnic University implemented an optical braille recognition technique using edge detection to translate braille into English or Chinese text. [4]
