Virtual QWERTY Keyboards to be used with Fingers...

I don't think qwerty is what we want really.
Also that it requires only one keypress per letter is not fully true, as you
have to use "shift" very often (capitals, special charakters, ...).
Imho the display on the neo is way to small to have qwerty. The iphone
shows, that eben the much bigger screen (without a high bezel!) is not
really great for a extremely basic qwerty variant.
I'm currently working on another system that requires one drag per sign (no
matter what sign, be it capitals, special chars, ...) and can be extremely
easy and fast with a proper layout.
You can see a basic preview here:
I'm a total newbie in programming, but I expect some results in the next
The system allows 144 key-combinations with buttons big enough to easily hit
them with your thumbs.
It allows fast one-handed writing of all ascii-signs and it will be very
flexible with the layouts.
So it would be possible to have a layout that allows single-click without
dragging for keys needed often in a row (backspace/del e.g.), as you can see
with the "o" on the video. I'm writing "HelloWorld" there (you can see the
output on the terminal, as there is only a stdout-function at moment), the
"Hello" to show the interface, the "World" to show the speed (that will
improve quite a bit so that the interface will be fast enough to follow you
:) ).
Of course in the end it will be on the bottom of the screen as the old
matchbox-keyboard is (at moment I'm working on the matchbox integration), so
you can hold it in your right hand and type with your right thumb without
needing the left hand at all.
It doesn't even need prediction to be fast and easy, although it would be a
possibility to enhance it.
There's a tarball with the source, but not ready to be usable, so I will
release the code later.
Interested people can have the link and maybe an ipkg, but I'd recommend at
least to wait until the matchbox-integration is ready.
