Smart glasses: a new tool for cheating on exams in China

In an interesting article on the popularity of smart glasses in China, our colleagues at Rest of the World discuss one of the unexpected (or perhaps not so unexpected?) uses of this relatively new gadget: cheating on exams. A parallel market for renting smart glasses among students. We already knew these glasses as tools for hidden cameras; now we're discovering them as instruments for cheating, especially the models equipped with screens. One of the students interviewed even explains that he rents his glasses to other students, in addition to using them himself to "assist" him during his exams. There is, in fact, a whole market for renting smart glasses in China, and most of the customers are generally young students. Naturally, these devices are prohibited in classrooms, but some models are so discreet (the camera is barely visible) that supervisors cannot always distinguish them from regular glasses, which are essential for some students to study.
