[BlindMath] Reading wiki page containing formula

[ckgoodwin85 at gmail.com]

Hello Lilian,
Thanks for your clear instructions.  I am all set up with Math Player.
I follow the explanation of the algorithm up to the last step where I don't
understand why two lines get created and not just one like in the previous
two iterations.
I think the answer is in the 5 line equation detailing the Euclidean
algorithm but I don't follow this.  What are r and q for example?  
But Math Player does now cause me a small problem because I now don't seem
able to get the LaTeX level text to step through one character at a time
which I wanted to do as you were saying that the letter a can get mis-read
as an r sound.
Copying and pasting a text selection covering the long equation doesn't
help.  There seems to be nothing there.
But in general Math Player is pretty neat.
Best, Chris

Hi Chris
I've managed to do the following with NVDA to read the maths on the
wikipedia page, Euclidean Rhythm
<https://en.wikipedia.org/wiki/Euclidean_rhythm>.
1. Apart from NVDA, you need to install Mathplayer 4. You can download this
from the Wiris website. In the following page, go to the link that reads 'a
free download from our website':
https://docs.wiris.com/mathplayer/en/mathplayer-user-manual.html
2. After installing the download, I would restart your machine.
Go to the Euclidean Rhythm page (using Google Chrome or Firefox) and
navigate to the heading "Summary of algorithm". Start reading the paragraph
that starts with " In Toussaint's paper". It will stop every time it
encounters maths. You just have to use the down arrow to listen to the
maths, then down arrow again to continue the sentence. Every time you come
to a pause, it is likely to be waiting for you to press the down arrow to
read the maths or continue the sentence.
See if that works for you?
When you get to an equation that you want to interrogate slowly, press Enter
on the keyboard. It will read the maths out to you again. Zoom in by
pressing the down arrow. You can then explore the expressions at sub level
1 by using the right and left arrows. If you want to zoom in further, say
sub level 2, you can press the down arrow again if that part of the
expression has further sub levels. If not, zoom out (up arrow) until you
hear the whole equation or press Esc on the keyboard to come out of reading
the maths. Down arrow will then move to the next part of the sentence again.

I did notice, however, that NVDA can be quite erratic in what it reads. For
instance, it can say 'ah' instead of 'a' for the letter a.
One the Euclidean Rhythm page, there is a list to illustrate Euclid's
algorithm. Instead of saying Q sub zero, it reads 'sub zero', trying to
pronounce the Q quietly. It does the same for the letter r. It could just be
the way my NVDA is set up though.

I hope this helps. I'm still learning the ins and outs of NVDA and maths
though so hope someone with more knowledge can contribute!

Regards
