Re: introduction and question about braille unicode

Currently it's not possible to have something announced but have something else shown on a refreshable braille display unless you try to do some hack with aria-live, etc. So if you had a math equation that was written in a certain way such as written out as words but you wanted to have it displayed in braille using UEB math or Nemeth it would not be possible. As mentioned the new aria-braillelabel attribute which I doubt is supported by assistive technology hopefully will solve this issue at some point in the future.

Hello Peter,

Thanks for the resources! Much appreciated! Will have a look.
The site we are working on uses braille patterns to draw some graph on the braille display. It isn't a regular graph, but an actual overview of the graph which we calculate according to some method we have developed. We need to use those patterns to have full control on the shape of the braille data we want to draw on the display. Do you have an access to a braille display so I can send you some sample you can examine if do you think this is necessary?
Happy to elaborate more on what we are doing if this is not clear enough.

Have a great time!
Mohammad
