It would be nice if x itself implemented an accessibility framework, but it currently doesn't as far as I know. If it did, people with disabilities wouldn't be limited to gnome, which would be again nice. > eg. speech input, braille display, etc ? I'm not sure what you're getting at in the above example, can you please elaborate? If you're saying that there should be a driver for a braille display, speech input, or speech output just like there is for a mouse for example, then this isn't that simple. With a mouse for example all you have to do the way I understand it is to track the mouse movement, move the mouse pointer on the screen by the same amount, and track if buttons were clicked, and where the pointer was when the buttons were clicked. In the case of a braille display, you can't simply send video output to it, because it would make no sense. Doing so would be like sending an audio file directly to the sound card. You instead need a audio player to interpret the audio data, and play it to the sound card. This is what brlTTY does for example. It not only drives the braille display, but grabs video from the text console, formats it into something the braille display can act on, and sends it to the braille display. The orca screen reader does much the same thing with graphical output, but uses brlTTY to drive the braille display, instead of replicating that functionality itself. The same is true for speech input, and speech output. Software listening to input from the microphone needs to interpret the audio, and execute the required action(s). You can't send video output directly to the sound card, because that would make no sense. Software has to grab the video output, interpret into text, send that text to a text to speech engine, which then sends that audio to a sound card. This is all quite over simplified, but I hope it makes sense.
