Wow, I hadn't thought I'd trigger such a long thread. ;-)

It would indeed be nice if the touch screen had an output that plugged
into the computers mouse port (or looked like a USB mouse.) Of course, as
someone mentioned, that means that our input is essentially mouse "clicks"
and not anything having to do with dragging.

As for the size of the buttons, wxPython does allow the user to define
button shapes and sizes - so they can be super-sized and of whatever color
and pattern we want. Big buttons does, however, mean that a full ballot
full of contests won't fit onto the screen at one time.

How does the diebold and other systems deal with navigation through a
ballot that occupies several screens?

As for touch screen wipe-downs and styli: I'm concerned that someone will
pull out a ballpoint pen and punch a hole in the thing if it is covered
with a film rather than a solid and somewhat inpenetrable layer of plastic
or glass.

As for telephone keypad input: I like the idea, but I wonder how to
integrate it - we would depend a lot on the ability of the user to
transpose information on the screen to a button on a keypad - and I'm not
sure that all people can do that.
