1 Nov 2006: Touchscreen Calibration Issues with Voting Machines
Direct-recording electronic voting systems from several major vendors, including Diebold, ES&S, and Sequoia, have touch-sensitive screens. The screen shows pictures of buttons with labels for the various candidates, which the voter selects by touching the screen with their finger. Some voters using these machines have reported problems where they pressed the button for one candidate and a different candidate was selected. These issues are most likely the result of poor touchscreen calibration rather than any security problems with the voting machines’ software.
