[Blindmath] Issues with electronic math files and screen readers/braille displays

Thu May 10 21:49:27 UTC 2012

Steve you make some very good points about why MathML should be a 
preferred option. One thing you didn't raise in that is that for some 
audio might not be suitable eg. those who are deaf and blind, in that 
situation Braille is possibly the most appropriate output. MathML 
abstracts away from the output system letting the software choose how it 
should be presented.

That is certainly better than nothing, but it leaves a number of problems that would not be present if they actually took the time to use MathML. And to be honest, I would not be surprised if they were actually spending a lot more money making all the recorded audio than they would be if they just spent the time creating the MathML.

For instance, Nemeth braille users can hear MathSpeak simply by switching the output style in the software...just a simple click. But that speech isn't something you want to use with LD users. For example, MathPlayer 3 lets you select the intended target user and so get the kind of speech that works best for the student's disability. When recorded audio is used, you only get "one size fits all."
