Re: [Ipodlinux-devel] OT?: Text entry via a circle..

[Jean <jwl...@fr...>]

Hi!
It would be interesting to see if iPod touch wheel can detect 
fingerpresses ON the wheel (sorry for old mechanic wheel iPods). Maybe a 
good idea would be to link the char input process with an "T9" like 
input, or "unix-Tab" like input... I should install linux on my iPod as 
soon I'll have time.
I have some C/C++/Delphi skills, but not under Linux/Unix :o(
Jean.
