Sorry about your injury.
To my best knowledge there is no hardware keyboard using the Fitaly layout. (You may email Textware support directly to verify.)
If your PC sports MSWindows, there might be a workaround. There is a beta version of Fitaly for the Tablet PC available which can also be used on Win2000 and WinXP. Take a look at the
Fitaly Test Forum, especially at the post
Announcing Fitaly2003 for the Tablet PC. Personally I strongly doubt that this makes sense without a touch screen, selecting the letters one by one with the mouse.
Did you take a look at the accessibility options in system settings to ease one-handed-input by making Ctrl- and Alt-keys sticky? (Assuming MSWindows again)
HTH nevertheless,
