Hello everyone, i'm trying to develop kind of a computer, that i strap to my lower arm.

i'd call it a wristwatch computer, but i know it's gonna be bulky, so i'm pretty sure that name would be a bit misleading.....

Anyways, i need some help.....i need a good way to input text, without having to hadd a huge freakin' keyboard.

i've looked at keypads, and they may work with some special planning, but i'd like to find an alternative if i can.

So basically, to sum up a long story, i need help coming up with ideas for text input. :D

Hi Master_Programmer,

You could possibly try a interface were you have 1 button and one press goes to the letter A and 2 press goes to letter B and so on. This could take some coding time and it could be kinda slow. Are you aiming for one of those old calculator watches were the buttons are super tiny? You could possibly hack one of those keyboards. Also there is a keyboard chat pad for the xbox 360 that is just about 4 inches long

Interesting idea......and i'm not making separate buttons for each key.....i don't have that many buttons lying around, and i'm trying to make this project cost as little as i can, because it's gonna be one of those "I'm probably the only person in the world who would ever want/like to use a device like this" projects. XD

but to anyone who's interested, i'll post pictures once i get some solid progress on the device. :)

Hi master programmer,

What do you mean A01 text and 5 by 10 size on the LCD? That could require you having to make custom LCD characters. I can Post some code if you want on how to create custom lcd characters. Have you completed the guide yet? Because that can offer a HUGE amount of knowledge on how to code and solve common problems.

According to this thread the Nerdkits LCD only has the A00 character set.
