RE: Touch Screen Calibration with BS Software



Granted.  If the calibration has moved that far out on its own, then there is a serious problem. 
 
Although we'd like to expect that competent people will use the calibration routine, imagine what would happen if when calibrating, they hit anywhere but the calibration targets.  Or the person's shirt sleeve hits the touch screen off target while they're steadying themselves to hit the target.  The calibration routine will adjust its matrix to that new information and would be completely out of calibration.   Without keyboard navigation in this scenario, it may be impossible for someone competent to select the calibration function from the touch screen.  The feedback they get from experimenting with touches to the left or right may indicate that to activate the button, they have to touch two inches off the left side of the screen.
 
It would be useful to recover from this situation without having to reload the WinCE image.
 
Another area where keyboard navigation would be useful is during the manufacturing process.  When powering units for the first time, the calibration settings are unknown.  There needs to be a method of selecting the calibration function in case the initial touch screen calibration will not allow activation of this function through the touch screen.
 
The specs are attached below.

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?

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 - Diagnostics
