I have been thinking about this too. My vision has been that this would be
completely independent of any screen readers, but of course screen reader
support might make it more capable.

I don't know, but I assume that recognizing touch gestures has quite tight
real-time requirements. I'm not sure if an interpreted and garbage-collected
language is the best fit for this kind of task.

I think uinput is a good way to go. It may even be possible to make it so that
it does not need BRLTTY's braille key translation, but can input straight to
the Linux console (if that is where you want to run this).
