Two of the example polls in the site screenshot are political (us 2020, cannabis).<p>I'm wondering how you get background demo info on poll participants?<p>I think it could be interesting to think about using visual cues from video (gender, age) but what about info like is registered to vote or other demographic info.<p>I don't see example of the hardware but I'm guessing this is like those smiley face poll stations in that it just collects a simple response and doesn't collect say first, last, address, birthday etc?
