For those unfamiliar with Braille, here are a few definitions to help you. Feel free to email me with any additional questions.
Braille embosser: The machine that physically presses Braille on to the paper. These devices can range in price from $2000 to nearly $100000. Some examples include the Everest Basic D, Romeo, Juliet, Braillo and VersaPoint.
Braille translation software: A computer program that converts print files into Braille. Some examples are Duxbury, Braille2000 and Megadots.
Cell: a 6-dot pattern consisting of 2 dots across and 3 dots down. From these dots, all Braille can be created—even music, math and foreign languages. Standard Braille paper is 11.5 by 11 inches. It’s 40 cells wide by 25 lines down. A smaller paper, 8.5 by 11, which is standard print-size, is 32 cells wide by 25 down.
Contraction: A single cell or group of cells that equal words or parts of words. For instance, “ar” is a contraction. The word “with” is represented by a single cell.
EBAE: English Braille American Edition. This is the system of Braille used before Unified English Braille (UEB.) It’s rules for contractions and formatting are what a lot of people who are blind are familiar with prior to 2000.
Grade: A system of Braille that represents how the Braille appears. Grade 1 is uncontracted. Grade 2 is contracted.
Interpoint: The ability of a Braille embosser to print Braille on both sides of a Braille page. This greatly cuts down on space without ruining dots.
Tactile graphics: The ability of a Braille embosser to draw complex graphics using Braille dots.
UEB: Unified English Braille. This is the newer format that Braille is adopting in all English-speaking countries around the world. It is now being taught to children.
