keyboard codes from external keys

hi everybody,

does anybody know a solution which does the following:

a set of "normal" keyswitches (simple connectors) trigger some
black-box-device which outputs keycodes to the PS2 keyboard socket.
so my application could read these codes and behave accordingly.
this is for the navigation on a fixed kiosk-system where there is a set of a
few press-keys rather than a normal keyboard, and no mouse interactivity.

thank you

Touch screens generally work better for this.
The hardware interface is not difficult and there should be plenty of things
like this on the market already. Did you try Google yet?

There will be no screen to touch to.
this is a beamer presentation with some interactivity via selection keys.

thanks peter

Couldn't you wire the switches to a standard keyboard ROM chip and have software interpret the codes any way you want???

That's shooting from the hip. Tony. . .

Thank you, hip-shooter..*grin (how nicely put)

I thought of this, too.
But I want to avoid do-it-yourself-bric-a-brac-solutions, when I sell an
installation to a professional client.
There must be something on the market, I bet, that does these things.
perhaps I am in the wrong newsgroup ... is there something like an
audio-visual-user-newsgroup around somewhere?
does anybody know?
thanks
peter

O.K. then, and pardon me for being explicit, but what language will you be coding in? One other thing I thought of is
that perhaps you could alias the C(++) mouse events functions. I'm no expert but the C(++) libraries does seem to have
some exellent functions which are not too hard to put to work writing your own event-handler - or something of that
sort. Talking as you do, I am suspecting it might be more of an Assembler project, and then I will be left behind, more
or less completely. If 'C' would do it for you, I'd suggest one/some of the NG's along those lines - lots of friendly
people there too. For the Hardware side of the matter I do not believe - at least I can't think of any ready-made
solution that you could cannibalize off of. A ROM chip is as close to the Blackbox principle as I can think of.

But then, if you have switches that report the neccessary events I am thinking that you ought to be able to build the
Blackbox completely in code. That's what a ROM chip IS, after all. I suspect the easiest and cheapest and speediest
approach would be to put a pc in there and attach the whole thing into the ps2 connector and write a device driver as a
Blackbox. Much in the way Arcade machines are built, I understand.

Greetings Peter, and good luck.

(By the way - what is a 'beamer', again?)

A quick Google (special purpose input devices) found a couple of interesting
things. You may even find a more appropriate/helpful newsgroup this way.
http://www.keytools.com/keyboards/cykey.asp
http://www.keytools.com/input/buddy_button.asp
I'm sure there are plenty of domestic products also. If you have a large
enough requirement, it shouldn't be too hard to find a company that will do
a custom design.
