Within the Pavilion of the Future, participants will encounter a bewildering array of rooms arranged to form a maze. ... Artists will also be invited to install various kinds of voting devices in the vestibule of the Pavilion. ... All will offer up a stark and simple choice: Will you vote for hope, or will you vote for fear? ... Voting booths will also be stationed at locations throughout Black Rock City.
All of these devices will be connected by a closed Wifi network, and linked to ... determine the statistical mean of our participating community's hopes and fears at any given moment. As a result of these measurements, the Burning Man will either ascend while slowly raising its arms, as if to welcome all our hopes, or descend into a cage of fear located atop the Pavilion's elevated deck. ...
Ok, so how's this "closed WiFi network" going to work? Lots of projects (including one for a group I'm working with) will have this kind of hope/fear voting capability. Ours will already have a computer that will change behavior based on the participant's vote, so how do we integrate this with the main voting system?
Speculating -- a.k.a. "if this were up to me" -- I would have a WiFi secure web server set up centrally. Prior to the event, people with voting-type projects can request access to the server. If approved, they'd receive a passcode which they'd use as part of an HTTP request. For instance, if a participant votes for hope, they'd request something like:
Code: Select all
https://19.48.1.11/vote?code=1234&vote=hope
for hope or
Code: Select all
https://19.48.1.11/vote?code=1234&vote=fear
for fear.
At least, that would work really quite nicely for our project.
