Re: Styling text for Braille Display?

aloha, gary!

thanks for the info on TarHeelReader and the pointer to your projects...

as for controlling braille "styling", one has a choice of using 
either CSS2 or CSS 2.1's media types -- braille is the applicable 
media type for refreshable braille displays:


CSS 2.1:

a "preliminary requirements analysis" for Braile CSS can be found

then there is the still-born CSS3 Reader Module,

which was "dropped" by the Style activity at the W3C in March 2008, 
despite CSS3-Reader's promise to:

The keyword 'reader' is a media type for use in Media Queries (similar 
to 'screen', 'print', 'projection', etc.). Devices that might choose to 
apply rules inside '@media reader' are devices like screen readers, that 
display a page on screen and speak it at the same time, or display the 
page and simultaneously render it on a dynamic braille device. The 
properties that apply to this media type are therefore the
combination of the properties for screen, speech and braille.

and i can not identify a clear-cut successor to the CSS3-Reader module,
or anything like a CSS3-braille profile (remember, in CSS, "braille" is 
refreshable/dynamic while "embossed" is static, paged media -- i am 
including bert bos, the w3c's CSS contact and the wai-xtech list in 
order to tease out an answer to your question)

there is also information about the braille media type in CSS3's Media
Queries Candidate Recommendation:

a "snapshot" of the state-of-the-art in CSS is contained in the 
CSS Snapshot document (a.k.a. CSS Beijing)

which, like the CSS working group's "current work" document:

does not contain any specifics as to using CSS to control refreshable
braille displays, but i am sure that there are many others on this 
list more knowledgeable about the subject than i am...  i just wanted
to provide you with some pointers and points-of-departure...
