Audience voting
The audience casting votes from their own phones in a contest or for an award.
Audience voting makes the audience part of the decision. To be trustworthy, each attendee should have one vote and it should be clear when voting opens and closes.
In Superevent's Live Voting and Jury module the public vote allows one vote per attendee. The organizer sets when voting opens and closes; the result is calculated live and can be sent to the result screen.
