im going to say that there are about 34 buttons on a keyboard
that you really need

minus key pad teh F1-12 one shift windows ctrl alt

would 5 keys being hit in diffrent combos be enogh to cover all the keys?

i e you can hit button 1 for a button 2 for b and if you hit button 1 and 2 at the same time you get y or somthing
 
im going on the idea that you can use all 5 at once andy any combo in between

1 and 4 for example

or 1,2,5 as another example

or 12345
 
Or we could simply plug the PS2 cord from our ear to the computer and let the amount of earwax we secrete control the keys, and just learn how to controll our earwax

5 keys, in any combination for a 5-digit code gives 3,125 possibilities.

5 keys, without repeating a number for a 5-digit code gives you 120 possibilities.

4 keys, in any combination for a 5-digit code gives 1,024 possibilities.

4 keys, without repeating a number for a 4-digit code gives you 24 possibilities.

Does that help?
 
not exactly how i planed it


the combos are by hitting buttons at the same time not keying ina sequance

sequance would give you more possibilites but i think it would be harder to remeber and slower to use

i guess its just going to b 5^2

sinice its like binary with the keys only having down and up

so

1 2 3 4 5

Those kinds of keyboards already exist and I don't see the point since it would prevent touch typing and be pretty inefficient.

I think you mean 2^5, but yeah. That's 32, almost as many as you need.

If you let the thumb control two keys, so that it has three positions, then you would get 48 (2^4 * 3).

*confused* Why would it prevent touch typing? Doesn't that just mean typing without looking? It shouldn't be any harder to learn a five button keyboard than it is to learn to play the trumpet. (Trumpets have 3 buttons plus to adjustment slides.) I never knew a trumpet player who couldn't play with his eyes closed.

I should have said regular touch typing, like with all 10 fingers.

Edit: Found it!

The Nostromo SpeedPad can be similary setup through it's drivers but I still can't find the one I'm thinking of.

It's still comparatively inefficient, but would be well suited for portability applications.

its not for sitting at a desk i was thinking of a more mobile solution like in an airplane seat or a car ( most likely not driving)
