NVDA and MathML, specifically for Chemistry Markup Language [Subscripts in Particular]


Andy Keyworth
 

Hello,

I'd like to find an answer about if NVDA can be configured to read MathML, WHERE the MathML is being used to represent chemistry. The main issue is that NVDA does not currently seem to read the subscripts in chemical equations.

Thank you,
Andy Keyworth

Hi Andy,

Do you have MathPlayer installed? NVDA uses MathPlayer to read MathML, and it generally reads chemical equations in an unambiguous understandable form although not necessarily the same way that a chemist might read it out loud. If you have MathPlayer installed, and it is not reading the subscripts, can you send an example of a webpage where it is not being read, and I can take a look.

Hi Greg,

 

Thank you for your response.

 

I have MathPlayer already installed; unfortunately, it doesn’t seem to make any difference. When I test these pages (in NVDA and JAWS across multiple browsers), I’m only hosting them on my local machine, not a web server. Non-chemistry MathML seems to display and be read fine by NVDA, at least in FireFox. But MathPlayer doesn’t seem to make any noticeable difference. Any advice on what I could change would be appreciated. Please see a demo sample attached as a ZIP to this email.

 

Thanks,

Andy,

              This particular group does not allow attachments.  You can try using the "Reply to Sender" link at the end of one of Greg's messages to send that attachment directly to him, and I believe this will work.  If you want to test that out, use the Reply to Sender link at the end of this message to send something, anything, to me as an attachment and I'll let you know whether it makes it or not.  I believe Groups.io strips only for on-group content when that's the chosen option, but not for private messaging.
