[Blindmath] Accessible visual objects by a screen reader

Mon Dec 17 22:46:58 UTC 2012

Hi Michael,

That was really awesome information. It helps me understand the options that are available in the current context. Both your mails meant a lot to me. I m studying on various aspects in accessibility and look forward to being in touch with you.

Warm regards,

Kiran

I imagine there are image conversion tools out there capable of this, but another option (probably not ideal) would be to load the SVG in something like firefox or recent versions of Internet Explorer, and then use print and one of the print to PDF tools. You probably would need to crop such a resulting PDF, but I know that all tools would be free.

However one thing which can be used should you have a set of X-Y data, if you were to get excel to export the data as a text file with multiple columns (columns separated by tabs and rows on new lines), then you could use other tools to get some sort of accessible output (eg. MathTrax will attempt to provide a textual description of the X-Y plot as well as an audio graph). Remember though, such solutions are very specific to certain types of charts and so are far from being a general solution.
