For example, I'd like users to be able to install an "add on" that
augments
the browser and "reads" MathML to the user using the native TTS
engine on the
platform. This isn't a plugin in the traditional sense as WebCore is
doing the actual rendering of the content.
I've looked at Chrome extensions but that seems to be at a higher
level. What
I want to do is add semantics associated with a certain kind of
markup. Think
of it as a "speak Math" service.
Any ideas?
Code to enable reading of MathML via assistive technologies should go
right into WebKit itself - that's where we have the support for
reading paragraphs or tables. It doesn't have to be an extension.
WebCore/accessibility would be the place to look. In particular that's
where code to read math via VoiceOver on Mac, Orca on Linux, or tools
like JAWS or Windows-Eyes on Windows. I'm not sure if that's the sort
of thing you have in mind.
