I'm sorry, Susan.

You say that "Asciimath is for simple math".

I know Asciimath ten years ago, and there is a web for transcbeing math into math braille code used in spanish and portuguess languages ("www.transcriptor.net"). With Asciimath I've prooved it for transmatrix and determinants, limits in differents forms, derivatives upper degree, double integral...

Can you say something imposible to exprime with Asciimath?



Saludos

I would definitely NOT choose ASCIIMathML as a general solution.  This system is quite incomplete and was designed for simple math.

I strongly suggest Word with MathType for sighted persons.  There are various options so users can learn appropriate shortcuts as they get more familiar with the system.  And don't forget that in a typical document there is a lot of repetition so that much time can be saved by using copy and paste for parts of expressions as well as whole expressions.

By the way, many math transcribers in the US prefer to enter Nemeth math directly.  I think this is a poor solution.  First, it makes proofreading almost impossible. Second, it requires considerable specialist training.
Finally, and most importantly, even though it may take some time and effort to fully implement an automatic process for translating MathML to braille math, once it is done it will be much more reliable, efficient, and cheaper than humans could ever be.

There is a wonderful company in India called River Valley Technologies with a business based on converting from LaTeX to MathML. CV Radhakrishnan, one of the founders, is very experienced, very generous and has a deep understanding of the issues surrounding electronic math.  I would suggest you contact them for advice.

There is another company in India called Webel Mediatronics that sells software to support  braille production in various Indian languages and software called WIMATS for converting to Nemeth braille.  My understanding is that WIMATS has its own input system for math.
