Re: designing a screen reader

[Charles McCathieNevile <charles w3 org>]

Designing a screen reader that reads the content of a screen in linux assumes
that there is a single screen, which is basically a flawed assumption. For a
given output stream, such as a particular virtual console or terminal, there
is an output stream that you can find. I would encourage you to look at the
gspeech work that paolo is doing, adn if you think there is value in making a
non-open-source screen reader maybe you could do something similar for some
other flavour - KDE perhaps.
