Re: [orca-list] A web-based accessible graphing calculator. Hurray!

[Peter Vágner <pvagner pvagner tk>]

Hello,

I know I'm now mixing a lot of things together but I've noticed that orca presents some live region reports twice for example when chatting at messenger.com message list is configured as aria-live region. As new messages arrive orca is reporting them twice.

Related to that web based calculator it might be the same issue if those are live region updates not text navigation I've observed.

And finally can you recommend some site or an app where I can experience MathML support built into orca?
Also what about D-pub specific role types? Are these expected on the web or is it likelly these might also be supported inside a document somewhere e.g. when opening an epub book with evince?
Libreoffice 6 now supports exporting epub and tagged PDF documents. Perhaps we should look if it is possible to create our documents with these roles in our mind.

Greetings

Peter

Hey Peter.

I'll take a look. But that calculator relies mainly upon live regions
for access rather than Orca's native caret navigation and MathML support.

Thanks!

 Hello,
 
 This looks like a very accessible web app.
 It's a great way on how to experience orca's MathML support I guess.
 
 This calculator has so called expressions list. When I type an
 _expression_ into one of the entries the _expression_ is evaluated and orca
 reads it in full.
 Also as I'm pressing home and end keys it's reporting start / end of the
 _expression_. Is there a way to read such a MathML _expression_ by members?
 For example just to test how this is working I have came up with a
 random _expression_ like this
 \frac{3}{4}\cdot\frac{1}{2}
 
 When I navigate over the entry field in Firefox 62 by character (using
 left and right arrow keys) current fraction is often presented twice.
 Also the fraction is announced in full when I navigate to it however the
 bottom denominator does not appear to be reported to me. Orca just says
 after start fraction and then the whole fraction when navigating left to
 right and it is not reporting the bottom part of the fraction when
 navigating right to left.
 
 Please excuse me for a dumb question. This is all very new to me so
 perhaps I first need to learn it properly. Still if you can I would
 appreciate some hints.

 Hey all.

 I am currently at the week-long Web Accessibility of Mathematics
 workshop at the American Institute of Mathematics. Just saw a demo of a
 web-based accessible graphing calculator. It works with Orca. Hurray!!

 Note that you'll probably want to toggle Orca's sticky focus mode on
 when using it because when you use the application's command to exit the
 entry and interact with the graph exploration utilities, the app gives
 the focus to some nameless button and that triggers Orca to switch back
 to browse mode. I've requested they add role="application" to the body
 element (like Google Docs does) which would prevent Orca from bouncing
 you out of focus mode. In the meantime, when I enabled sticky focus mode
 in Orca, the calculator worked quite well. I'm curious what you all
 think.

 Happy graphing!
