Keypad for fingers, not stylus

[Mikkel Meyer Andersen]

Hi,

I've started a little project: to make a keypad where it's not required 
to use the stylus, i.e. the fingers should be used instead.

The plan is to make an alternative to the matchbox keyboard so that the 
new keypad can be used both in terminal, for texting etc.

So far I've only implemented the very basics, e.g. to write a "c" three 
pushed on one butten is required. I've also plans for implementing a 
dictionary, e.g. T-9 or an alternative: the most common words appear 
based on the already entered letters (if "ba" entered manually by 
pressing a sequence such as (22,22,2) then the phone should propose for 
example "banana").

I'm already thinking about the data structures, search algorithms etc., 
but I'm really not that sharp at C (only at C# ;-)), so it would be 
great if someone would participate in especially that part (which also 
includes to compile it to ARM and not just x86). I've submitted an 
application at projects.openmoko.org, but haven't got an answer yet.

I've attached the code I've got so far. Sorry if it's too ugly, as told 
my C is a bit rusten :-).

Please feel free to comment both code, ideas etc.!

Regards,
Mikkel Meyer Andersen
