Delays in Live Streamed Video Can Cause Problems for Clicker Quizzes

Livia Lam, & Tom Worthington,
hosting the Govhack 2022 Trivia, 
still from livestream, 20 August 2022
For months I have been taking part in weekly video conferences, helping prepare Govhack 2022. During that time I managed to avoid taking on more roles that the one I volunteered for: Government & Education Liaison. But during the last meeting before the event my video link stopped, & when I reconnected I discovered I was the co-host, Livia Lam, for the streamed Trivia event. We did this from a classroom at Torrens University's Sydney CDB campus. The format was much as used for live classroom quizzes, as was the technology used. 

Myself and the co-host were on Zoom, which was relayed to a Facebook live stream. The participants used a QR code to get to the software asking the questions. One problem was the delay of several seconds between us speaking, and when we were heard. The application used for the questions did not have the delay, so the questions we were reading out were after the participants had already answered. The delay was longer than just with Zoom, as the video then had to go via Facebook's system. Perhaps the makers of the quiz system could build a delay into it.
