Re: [Kde-accessibility] Annoucing libbraille

Hi Sêbastien:

Thanks a lot for your work in this area. I'll be looking more closely at libbraille in the near future, I hope.

I hope you can look at gnome-braille (in gnome CVS) to try and avoid duplication of effort. gnome-braille is mostly concerned with encoding and translation, and the rather tricky business of international braille, and not very much with hardware drivers, at the moment.

I agree that it makes little sense to have multiple braille APIs that appear to duplicate things. Note also that a "fake" braille display already exists (though it may not do as much as yours, yet), as part of the gnopernicus project, and if you build+install gnopernicus you can run the virtual braille display standalone ("brlmonitor").

I really think we should separate the issues of encoding/translation from the issues of drivers for different hardware devices. I understand the desirability of using dot-conversions that are either part of existing drivers or built into braille displays, and gnome-braille's translation APIs allow this on a mix-and-match basis. That is, braille translations can be cascaded both to handle mixed language situations and to support multi-stage translation (which is required by things like Japanese braille and also a good way of handling "Grade2" braille, true 6-dot brailles, and the like.

I put this in GNOME cvs as a matter of convenience, but think gnome-braille would be at home in, it makes sense to make such things common. I look forward to discussing how to integrate gnome-braille and libbrl effectively.

best regards,
