Keyboards for amputees

[Aristonaut]

I have a co-worker who lost a limb as a child (halfway up the forearm). I got excited that this may be an opportunity to help him out AND make a custom keyboard, which I really enjoy. (I'll let y'all know how that goes.) It all got me thinking that maybe there was already a group somewhere that may do this kind of thing and could give me some tips/guidance. So, in short, I am here to ask:

Is there a group you know of here or elsewhere that helps make custom keyboards for amputees?

I would love to help out in the future, too. I am not the most skilled fella on here, but I have built a fully custom pcb-less keyboard using the TMK firmware and a laser-cut case.

 You could make a one handed keymap on a programmable keyboard that works like this? http://half-qwerty.com/

Then you could build a keyboard without the alphas that is not used?

Or just take any split keyboard with a good enough firmware and assign the keys of the missing half to a layer on the present half. E.g. my keyboard could do it without much modification. But I expect it to be easy to do with any open split keyboard.

There are one handed versions of Dvorak: https://en.m.wikipedia.org/wiki/Dvorak_Simplified_Keyboard#One-handed_versions

With interesting 3D-printed designs, like the 5x7 dactyl-manuform, it's possible to create something very ergonomic.

Here I am contemplating how to map EEG signals to TMK/QMK firmware...

I used one for a few months after breaking my finger. I stuck with it for a bit afterwards as well, since it was nice to be able to drink a cup of tea while typing!
