Short intro:

3key demo - input method for touchscreen (both finger and stylus).

All good things are three. This is my third demo and it uses three keys!

goal

* Be usable with one hand (hold phone and type with the thumb).
- Reached in full.

* Use little space on the screen. The application should have it!
- Reached in full (take less space then the qwerty keyboard).

* Be usable without visual contact (type in Your pocket).
- Reached.

* Reach all chars and functions and be extendable.
- Reached in full, extendability not implemented in the demo.

* Be usable without training, even if slow.
- Reached, You should get it under one minute.

* Reach descent speed, even if it takes training.
- Reached, but takes allot of training and is still no high speed
   method. The speed is approximately twice as good with stylus vs
   one handed thumb writing. Two handed typing with one finger is
   somewhere in the middle.
