I’ve done some tests already. I’m seeing a 10 sec lag on what comes out of my mouth and what comes through the stream. The screen share seems about 3 seconds ahead of my camera’s live video. There is a 15 secondish lag between when you start streaming and the stream actually begins.
I was testing on a laptop that had a hard wire connection to my router at home… the receiving computer was on the wireless.
Here is their documentation which includes technical requirements:
Students could use laptops, ipod touches, or smart phones in class to respond to questions from the instructor. If you keep the “poll” or quiz open, you can also collect answers asynchronously for online/flipped learning. The answers are dumped to a spreadsheet, so you have all the data for assessment, attendance and participation.
