A university in China has installed facial recognition cameras in classrooms that monitor students' behavior such as nodding off or playing with their cellphones.
China Pharmaceutical University in Nanjing, East China's Jiangsu Province, is piloting the system in two classrooms and eventually plans to install it in every classroom.
"The system can access every student's personal information and monitor their behavior in class such as nodding off and playing with their mobile phones," reports Global Times.
The cameras can also record truancy, whether students are listening or not, how often they look up and down, and whether they leave early.
Students complain the system is an invasion of their privacy, but school officials insist the cameras are necessary to encourage discipline.
