Either that, or distribute the Powerpoint files with a little hand
out, explaining how to navigate PP documents.
In general, I wonder if any such guides exist and if it might be a
good idea to compile them.
Powerpoint with Jaws/Window Eyes, Google Docs with Jaws (an exercise
in frustration) etc.
I've done the screen reader specific instructions for a few minor
software things and users have very much liked them.
I was asked to write up a little guide for screen readers as a temp
solution for a web site that was not overly accessible, but going
through an update.
The guide explained how to do certain things on the site, step by step.
I've never seen anyone else try this, and it is true that web sites
should never require user guides for how to perform certain things,
but it was actually quite popular with the users of this site.
They felt they learnt something new with their screen reading software.
I guess I am not sure where I am going with this but, generally, I
think trying to push your users, teach them something new, ease them
into using Powerpoint, may be a good thing to do in some situations,
mostly educational settings.
It all depends on your audience.
