Why Does a Voting Machine Need Calibration?

New submitter Shotgun writes "I heard on the radio that there were some issues with voting machines in Greensboro, NC (my hometown), and the story said the machines just needed "recalibration". Which made me ask, "WTF? Why does a machine for choosing between one of a few choices need 'calibration'?" This story seems to explain the issue."

    I'm speaking from a perspective of someone that regularly works as a poll worker during elections in the state of California.

    One of the first things I do once our touch screen system is set up is confirm the calibration of the LCD panel. It's typical for the registration to be off by a few pixels, as our fingers are not perfect pixel-sized points. However, I have yet to experience an issue where the calibration is so bad that the wrong selection is made on behalf of the voter. Remember there are a whole host of perfectly valid reasons why this may be more of a problem for some voters than others, certainly including finger size and physical impairment affecting fine-motor skills.

    If a voter did report a problem of this nature, recalibrating the touch screen would be one of the first things I would try.

  6. Just crappy resistive touchscreens by JDG1980 · · Score: 4, Insightful

    Even before reading the article, I knew what the answer was. This is because at my workplace (a public library), we deal with a very similar thing on a regular basis. We have several self-checkout units at each branch, which are basically all-in-one Windows PCs running special software. They have RFID pads for scanning the books, and they take input via a touchscreen. The capacitive touchscreens on tablets and smartphones are generally of good quality, but these are different. They are crappy resistive touchscreens, designed to keep costs down. Accuracy is poor, and a calibration utility must be run regularly or the screens will start to drift. Calibration entails running a program designed for that purpose, then touching targets displayed in each corner of the screen in sequence.

    If calibration on a low-quality resistive touchscreen is off, then the mouse click may register at a location as much as 1 full inch away from where the user pressed. I have personally seen this happen many times on our self-checkout units. So if you hear a story that someone on a voting machine pressed the box for the Democratic candidate and it checked the Republican, or vice versa, I'd be willing to bet money that this is what happened. If they were deliberately tampering with the votes, why would they show that to the user?

    There are indeed serious concerns with the lack of source availability for voting machines, and the ownership of voting machine companies by individuals with partisan ties. But calibration is not some kind of conspiracy – it's the inevitable result of using cheap touchscreen hardware.

    First that letter was all about setting up a legal and public relations basis to question the election later.

    Second, yes voting machines need calibration. Different types require different kinds.

    For example the touchscreens, usually older resistive touch screens get mis calibrated on position. You have to remeber these things get locks in closets and sit in non-temperature controlled ware houses for a couple years at a time between elections, then they are jostled in trucks, cleaned with cleaners, and sometime run off various power sources. Empirically they do go out of calibration.

    I personally have a ballot I saved from an AUtomark paper ballot printer in which all the votes are off by one oval width. that is 100% of the votes are incorrect and you can tell because a few are printed past the range of ovals.

    Opscans are fairly easy to allign since they have relatively few degrees of freedom but they do get misalligned and become sensitive to printing tolerances.

    Old lever machines used to have the gears wear down.

    The solution to all this is not to require perfect everything but to have ways to check things. hand marked Paper ballots and some sampled recounts of those paper ballots such as is done in New Mexico is I believe the best compromise between transparency, robustness and simplicity. It's robust against human and machine errors so mere mortals can carry out very transparent elections. It's also robust against voter turnout variations too since it only takes more pencils to let more people vote, and if a machine breaks, you can still gather the ballots, so you dont get long lines at the polls.

      While we're at it, let's also do away with the electoral college. And yes, I'm being serious.

      Here is a simple example:

      You have three states. The first one is 10x larger than the other two, and the voting outcome is as follows:

      State A: 500,001 votes for candidate 1; 499,999 votes for candidate 2
      State B: 49,999 votes for candidate 1; 50,001 votes for candidate 2
      State C: 49,999 votes for candidate 1; 50,001 votes for candidate 2

      State A gives ten electoral votes to candidate 1, and states B and C each give one electoral vote to candidate 2.

      As you can see, even though candidate 2 received more actual votes than candidate 1, he/she winds up losing.

      The winner-take all rule makes sense whenever there is just one state involved, but when you carry it over across multiple states, you wind up losing accuracy. Currently there are only two states, Nebraska and Maine, which actually implement proportional voting by splitting their electoral votes. But even then, that is not 100% perfect because there are an integer number of electoral votes which are based on population size, so there is still a rounding error.

      The most accurate, and to me the simplest approach is to simply add up the actual votes from each state for each candidate, and only at the very end do you compare votes to see who is the winner.

      Los Angeles County uses Inkavote. Basically it's just a little rubber stamp you press into the circle on the ballot. The machines themselves have guides to keep you from putting the stamp anywhere but an oval. You insert the ballot, ink in the correct circles, then remove the ballot and turn it in. There are no moving parts except for the small spring-loading in the stamper and the hinges holding the pages in the machine -- which are themselves identical to the ones in your sample ballot as mailed to you. This means you can mark your sample ballot at home, hold it up alongside the corresponding page in the machine, and simply copy your bubbles from your sample ballot onto the real one.

      This has all the advantages I can think of -- it's almost non-mechanical and CAN be done by hand if there are insufficient machines available, it generates human-readable paper ballots, it's faster than a touchscreen system while also being far less complex, and it's easy to understand. There are many things I can gripe about, living in the Los Angeles area. The voting machines are definitely NOT one of them.
