[nabs-l] using Braille for math

Tue Aug 30 17:59:06 UTC 2016

Do you suggest that I use refreshable Braille, hardcopy Braille or a combination of both when using Braille for mathematics?
What do you mean by the fact that Nemeth is more "consistent?"
Which code is more efficient?

Thanks,
Bill

Although UEB is the international standard, Bana (the Braille Authority of North America specifically recommended keeping Nemeth because it is much more consistent in the context of mathematics and science notation than UEB Math. In fact, it is so much more consistent, that Pearson (the text book and testing company) is working on a math editor using Nemeth Braille. The developer has said that Nemeth is very easy for him to translate to and from print, but that he cannot see a way to do so using the symbols in UEB. Of course the instant translation would be of great benefit to both you and your teachers, as you are each reading in your native code.

I believe you need to be using NVDA, and that at this time, reviewing the Math needs to be completed on the display as speech will not read properly, (though they are working on this knotty problem).) but regardless, it's a pretty powerful tool that may be of benefit to you even though at this point it's not a fully rolled out product.

Every day we raise the expectations of blind people, because low expectations create obstacles between blind people and our dreams. You can have the life you want; blindness is not what holds you back.

Before, I wrote my problems in an improvised "calculator notation", where each line was written in a similar format to how it would appear on a scientific calculator (+ for addition, / for division, ^ for exponentiation, sqrt for square root, etc). This notation worked, but had several issues: it was ambiguous at times and hard to read for my sighted teachers.

That was, in short, a disaster; I was consistently lagging far behind my classmates when doing simple two and three digit addition and multiplication problems because of the time it took to interpret the Braille and manipulate the Math Window's tiles. I haven't used Braille for math since, using only a computer with a plain-text editor to do Algebra, Geometry, and Pre-Calculus. I have, however, used raised-line diagrams and three-dimensional models for Geometry and trigonometry.

The biggest problem with using Braille is that my teachers don't read it, so I'd have to frequently transcribe back-and-forth from Braille to LaTeX. This would be relatively painless for refreshable Braille, but less so for the hardcopy variety.
> If I used Braille for math, which math code (UEB or Nemeth) should I learn and use? From what I've heard, Nemeth generally takes up less space to convey the same content (important for refreshable displays with limited real estate), but UEB's presentation of that content is clearer. Also, Nemeth could be replaced by the UEB math code in a few years since it's the international standard now.
