I'm curious what the live video stream captures. Is it you, your desk, and several feet around you (i.e., enough to confirm that there's nothing else near you)? It seems like they need enough to do ongoing, real-time confirmation that your workspace keeps matching the still images you sent in.

FWIW the 'privacy' concern is often voiced by students who find the test proctoring intrusive. On the one hand I agree it's intrusive but on the other hand it seems reasonable for the short-ish amount of time (several hours) that they'll be taking the test.

I'm guessing that some fraction of the students complaining about privacy genuinely object to the privacy issues, some folks may object to having to pay a fee for the oversight, and some fraction are objecting in an attempt to get the oversight removed so they can cheat. I'm sure there's overlap, and other reasons that I haven't thought of.

The scalability problem(s) comes from the need to have a human watching each student take the test. The more people each watcher needs to watch the less effective they'll be, but the lower the watcher-student ratio is the more expensive it will be. Especially since a good fraction of the students won't cheat (so you'll be paying people to watch students not cheat for several hours).

The testing app shows you your video stream in real time, it's relatively tightly zoomed and cropped to your face. This is what leads me to believe that they rely heavily on eye tracking (and sound, they require that your mic be capturing too) to look for suspicious behavior. I'm not sure, because it's never happened to me, but I believe the proctor has the ability to interrupt your test and request that you show them the room.

The requirement is that you remain in place and keep your face on camera for the duration of the test, but depending on the test there's an "unscheduled break" functionality that will let you take an unsupervised break, at the cost of locking you out of all of the questions you have already seen on the test so far.
