I designed Samuwrite and V12 keyboard, two alternative text-input interfaces for touchscreens.
Here are links to two short demo clips.
Samuwrite may be useful for people with motor / visual disabilities or as a new means to teach children the letters of the A-Z.
V12 keyboard may have potential as a means for password authentication.
I am looking for partners who will be willing to test these interfaces and perhaps cooperate in developing them further.
