Its a touch screen they have no calibration that is a scam story!
 Quoting: Anonymous Coward 26142676

Two fitting comments from that Q&A:

Calibration? CALIBRATION?! Are you kidding me people? We all have smartphones for 200 bucks that are working just fine.

And this machine can't handle the only thing it's designed for?

Are you kidding me?

Smartphones use a different kind of touchscreen which do not require calibration. Most smartphones use capacitive sensing (The multi-touch kind). However, these voting machines use resistive sensing. These commonly require re-calibration, however, do not require you to touch with something with capacitance. Ie. if you have a glove on, or a "fake Prosthetic (What is the proper term for replacement limbs)" hand you can still operate the touch screen. This provides some sort of advantage in the case of voting machines, whereby people might be wearing gloves/etc or not have a hand made of flesh. They are also a lot cheaper to make. HOWEVER, these do require calibration. You might recall older PDA devices (or some tablets/phones these days) which used a stylus would have a "calibrate touchscreen app" which you would have to tap dots with.

edit: Just to clarify, I am not saying they should use them or not, I am just saying what they do use and possibly why they do....and mainly how they differ from smartphones.
