This week, by watching Queen’s video #tresdancing, a short film about screening surveillance. What I feel wow is about this video is the use of surveillance to help educate. At the beginning of the video, the girls were canceled during the exam due to some normal environmental influences. What struck me the most was that the system monitors a girl’s eye movements to make sure she’s not cheating. And what makes me wonder is whether this excessive surveillance system violates people’s privacy? For example, people’s identity characteristics, family environment have been recorded.
