It
would be interesting to know how the palm pilot handles mis-calibrations and
factory setups. They might do it through software controls or they may
have some interface port that allows for an alternate input
device.
Perhaps some of our subscribers have
had experience with these devices and would share that
knowledge?

Subject: RE: Touch Screen Calibration with BS
Software
In the new
calibration procedure, you have to press the three calibration points twice in
succession, with each try being within a small error factor of the
previous. You might accidentally miss a button once, but not twice, and
certainly not twice the same way. If you show me the specs, we can probably even throw
out "that can't be right" calibration input from
users.
Take a look at a palm pilot some
day. It doesn't have a keyboard. It does have touch screen
calibration.
Ken
During the calibration procedure it is possible to
touch the screen away from the calibration targets thus throwing calibration
off to a point of no return. Keyboard navigation to return to the
calibration function is the only recourse in this situation.
Keyboard
navigation probably makes some sense for the administrative
functions: tab through buttons, space to press button, etc.
But before we get in a knot about this, just how far out of calibration
can these things really get on their own before we just declare the touch
screen broken? I mean, its a big button, and you can always use some
smarts and touch a little to the left or right based on feedback. If
the screen is going out of calibration to the point that this technique
doesn't work, something is seriously wrong.
Show me the
specs.

Q: How would you select an "ELO Calibration" button using
the touch screen when the calibration is out to begin
with?
Q: Could a keyboard be used to select this function, if the
touch screen is so far out of calibration that it can't be selected
by using the touch screen?
Ian
Allow a user to do
the touch screen calibration from within ballot station software. With the ultimate goal of
locking users out of the OS, can a call be made to the ELO executable
so that it accessed from the System Setup -
