Karsten,

i agree with you about the layout of the chars ( on my example they was put
aleatory )! but at this point I'm just introducing another concept of a
finger based keyboard. I'm not able to know whats the better place for each
char optimized for English, Germany or even to Portuguese (my native
language, I'm Brazilian...).

For this use cases I'll try to implement some way to easy develop/change the
layout of keys (like i said at bottom of my page). Anyone could make their
own layout optimized for his language, share with community then you
download to your phone, when you need it probably you press some predefined
key on this keyboard, select what layout you want and dynamically change to
it. This concept is already presents in phones, like when you change the
input method to letters, number, symbols, t9...


what do you think?

Guy


PS:don't worry I'm still encouraged to submit it to SoC : )
