We used to use touch screen machines in my county in Pennsylvania and I was responsible for helping voters. Voters had lost a significant amount of faith in the machines because they believed they were misrecording votes.

I had no reason to believe the machines had any malicious flaws, or even issues the developer thought were errors.

What I did see was users trying to use a machine balanced on little stilts with hands that were unsteady, and to steady the whole artifice they would grasp the bezel with their other hand... And their palm would touch the top left corner of the screen. And like most low resolution touch screen devices, the machine averaged the input touch.
