Ask Slashdot: Setting Up Wireless Voting For Students? 167

RabidRabbit23 writes "I volunteer for a non-profit that organizes Model UN conferences for high school students. We need a quick and low cost way to record votes done by the students in large committees. There will be two or three committees with about 200 students in each. We need to be able to record yes, no or abstention votes and must be able to identify each student's vote. We looked into radio response clickers, but it is very expensive to buy 400-600 of them. They cost about $40 at university bookstores, which is way out of our budget, but we don't know what kind of discount we could get by buying directly from the manufacturer. We do have wireless internet but we do not have enough bandwidth to support everyone using a laptop. Does the Slashdot community have any suggestions for a better way to record the students' votes?"

    1. Assuming most of the kids have cell phones, you can set up a free Google Voice account and receive votes by SMS that way.

    If you set up specific strings for YES and NO (like 123 for yes and 456 for no), you can then search for that string in the results. The number of results you get is the number of votes. And if the votes are sent within a small enough timeframe, Google Voice will cluster multiple messages from the same sender into a single conversation (so people can't vote twice). If that's not enough for you, you can screenscrape the results and do a more precise count or go with some other sort of SMS system.

    But basically, if it has to be electronic and real-time, you're more likely to find cell phones on them than anything else.

    2. If it doesn't have to be so fancy, what's wrong with just having them raise their hands and counting them?

    3. Or maybe handing out very simple scantrons and borrowing a scantron scanner for your sessions?

    4. Or you could buy cheap laser pointers for everyone and have them point at two different lux meters for yes or no.

      Or, if you want a permanent identifiable record, take a photograph as people have their hands raised during each phase (yes, no, abstain). Use more than one camera from different angles to make sure you don't have occlusion problems. Have volunteers count hands live (each volunteer covering one Nth of the committee) to get real-time values that are approximate and sufficient for votes with more than, say 10 points difference; for close votes, use the photographic record.

        The scantron idea could be quick if it was parallelized. The following are assuming a single scanner.

        At one extreme, each student is filling out their own form, which must then be passed down the row and then scanned, presumably one at a time. Everyone votes in parallel, but you have to scan 200 forms serially.

        At the other extreme, you have a single scantron which is passed around, where each student answered one "question" (always the same number to track who voted for what). You only have to scan 1 form b

      1. Arduino-based IR senders are more than the $40 each the OP says is too expensive.

      2. If you used cheap TV remotes, how do you uniquely identify each student?

      3. 200+ students at once. That much IR on the TV remote wavelengths will interfere with each other so that nobody's signal gets through. Wireless vote-clickers are actually pretty complicated systems. Not only do they have to avoid interference, the system has to assure that every clicker sent a response (even if it was no-button-clicked).

        • In 2003, I was in a class where 30 students attempted to use IR transceivers to send an ID and an answer.
          The system worked like shit for the reason spazmania said above in #3:

          If a moderate number of students attempt to press the buttons on their remote, they all collide and attempt to transmit again.
          If a fewer number of students are sitting too far back in the room, they're unable to get a reliable signal to the receiver.

          The solution rigged up helped a bit, but keep in mind, it barely worked for 30 students

      Feeling a litte cynical today, and I know the reasons for the pushbuttons in the real UN, but I think that we really don't want to encourage the next generation to de-personalize voting, nor do we want to risk teaching them that technological solutions for voting are valid.

    You want cheap and you want to be able to identify each vote with a specific person?

    Certainly doing something with computers is going to be expensive in some way. It is also going to take a long time because not everyone would have their own computer.

    I'd suggest colored pieces of paper that are preprinted with a number. Red for no, green for yes, blue for abstention. Something simple like that. The pieces of paper could also be tagged for "Question 1", "Question 2", etc. Counting them wouldn't be that hard and they would be traceable - names could be written on the slips but even without that you would have the preprinted numbers. This would fall apart for blind students but would work for multiple languages.

    Sure, you could have some fancy system but it is going to cost money. Potentially lots of money. Anything that would require queuing up would likely get unmanageable quickly with 200 students.

    As someone who's used in-class polling systems quite a bit (I'm a college professor), there are only two solutions that will work. A dedicated "clicker" system (I recommend the ones by Turning Point [turningtechnologies.com]), or a non-technical solution. Paper ballots are obvious; the guy who suggested labeled poker chips had a good idea too.

    If you try to muck around with laptops and cell phones and polling websites and custom software and/or hardware, you're going to spend your whole time doing tech support rather than model UN'ing.

  • Ok, i am a geek. I understand you want to be fancy. But counting 500 votes manually takes 250 seconds if one person does it, and less if several persons do it. So unless you want a "real-time" result, i would think its ok to take paper ballots. Moreover it will be a record of the voting.

    On the other hand, i dont see why "the bandwidth is not enough" if you dont allow them surfing (or throttle it), then the BW should be fine, however consumer APs may have problems handling 500laptops. The problem is not to c

    This is just an idea, but maybe you could look into whether you can interface a logic board with a computer, and report to the computer which code is being received, and OPEN or CLOSE as yes or no. An abstention would simply be no vote for that code.

    It might be worth at least looking into.
  • if you want to speed up the counting of a non-technical solution, using something that has heft to it, like a pokerchip or marble might be the way to go. 3 containers for votes, whichever is the heaviest wins.

  • Have a locked metal box with a slot in the top, everyone takes a ballot from the vote register at the box, checks off their choice, and puts it in the box. At the end of voting you open the box and count the ballots. One of the hazards of working in the high tech industry is the tendency to overthink everything, to use more tech than is actually required instead of the simplest solution practical.
  • from experience Its perfectly possible for a chair to do hand votes for 200/300 delegates and you could always have tellers count if its close or use card votes and count them. The debate is the important part. maybe you need to read Citrine and/or Robbert's on how parliamentary systems work and all talk to some people with actual experience.
