[BlindMath] Learning High School Math

[Shail M]

Hi @Susan,

Hope, you are doing well. Thanks much for providing the references to the Math books.

Though Math equation speak is normally error prone by NVDA as well as JAWS. I lately learned that Math Player + Firefox + NVDA is the best among all options. I am trying it out. 

Canute is really promising and something that might be affordable compared to other notetakers. I really hope, this becomes the game changer and people with VI can read more content with scrolling for every line. 

Thanks
Shail

Hi Shail,

Thank you for reading my article and your nice words about it.

You mentioned an algebra book on OpenStax that seems like it would be difficult to convert to braille.  I agree.  It may be that the UTMOST project I mentioned previously is planning to provide some algebra books in braille.  You might want to contact them if the next two suggestions aren't helpful.

Here are two sources for braille books including algebra books which are available free to eligible persons.  A TVI should know what is required to request a book from either source.

The APH Louis database attempts to keep a record of every available book transcribed to braille for educational purposes.

BookShare has a huge number of books in various accessible formats including algebra books in braille.

You also mentioned the difficulty of working with a complex formula in either LaTeX or Nemeth.  There's actually been a lot of research in the area of how to explore complex formulas non-visually.  To take your example one possibility would reveal the outermost view as an expresson raised to a fractional power. The first  inner view is that the expression is a simple fraction.  Next one could explore the numerator and denominator and then their individual factors.

It is my understanding that both MathJax and NVDA provide for such exploration via tabbing.  I don't know the details of how to do this but perhaps someone else on the list can help.

As for manipulating the formula in braille it might be helpful to have an embossed braille copy.  Some people prefer to do braille math on a Perkins so as to read several lines at once.  The Canute 360 braille e-reader which has nine 40-cell lines  is just back in production so that will be another option hopefully available soon.
