Maybe a layout that can be added to the kii set?
If you practice 10 fingertyping than qwerty in normal typing is sufficient.
But if you can only use 1 hand and in my case only 1 finger than swyping (gesture typing) is ideal. MUCH than 1 finger typing.
Only then qwerty, dvorak etcetera all have the same disadvantage.
Swyping long words gets problematic. Because of passing so many superfluent character you often get very weird word predictions.
Dutch has a lot of long words
I made a layout that doesn't need passing not needed characters.
Only two rows, nouns and consonants, so it only works on 10 inch tablets or bigger.
But then it SEEMS to work great.
I made a rudimentary prototype for desktop pc, where you can swype words with the mouse. Swyping with the pc-mouse is very difficult, but I got the feeling that my zigzagkey layout would work with touchscreen
