There was a reddit thread on these anti-cheating software the other day, the threat mostly reminded me that I used to stare at the ceiling during exams.<p>And a bit more abstractly, they are trying to temporarily establish control over a space, so that their ml vodoo can flag suspicious behavior. A poster is actually a nice example, that they have problems with teenagers having a poster of their favorite pop star in their bedroom is an obvious, but there are probably also posters that get identified as a person with a probability of 10^-3 or so and subsequently flagged as another person entered the room during the exam. That situation is not improved by them not controlling the lighting of the room.<p>And of course, a institution paying a company to judge students is a recipe to ignore the students interests. We can assume that everybody involved thinks that minimizing false positives is important, in the abstract, however concretely this software is sold with a nice presentation to administrators and a nice UI for professors, minimizing the hoops students have to jump through, or their privacy, is not an immediate pain point for either.
