> What kind of cheat does it prevent?
Not much. When lockdowns first started I remember seeing _tons_ of first and second hand accounts of all the ways anti-cheating software failed when exposed to the real world.

It can be a little tricky. We put the test in a single full-screen window on top of any other windows, and...the students alter the transparency to view their notes behind it, or they notice that we only check windows in the current desktop or for the current active user. Maybe "full-screen" on the system in question only fills a single monitor and leaves another open for research.
All of that assumes that the student is only using a single device and doesn't have a hi-def pet silicon rock in their pockets at all times, hence the webcam monitoring and whatnot to check that a student is actively staring at the screen the whole time.

- oarsinsync 6y agoThis already exists for anyone sufficiently motivated. It's a video input playing back a prerecorded video showing absolute attention, with the device IDs coded to pretend that it's a video camera rather than a generic video input (e.g. HDMI input)

- Anthony-G 6y agoI'd fail if I had to go through this. When thinking hard about a problem, I like to clear my mind of visual distractions by looking out at the sky and if I'm not near a window, simply close my eyes.
- powersnail 6y agoNow I come to think of it... Reminds of when I was in middle school, we used a bug in Chinese IME to crash the software used to control our machines. The webcam solution also seems entirely bypassable if the student is determined. (Speaking from my experience as a TA, students who cheat are usually pretty determined) Just put a phone to the level of the monitor, and there's nothing a webcam can do.
