text: The Facial Action Coding System is a new software from Prof. Thomas Huang and Prof. Nicu Sebe that can recognize human emotions. This invention was tested on Leonardo da Vinci's Mona Lisa portrait. According to the software, Ms Mona Lisa is 83 percent happy, 9 percent disgusted, 6 percent fearful, and 2 percent angry. While the Facial Action Coding Systemmay seem like a high-tech toy, it could have some really important affects to help our schools. Having Prof. Huang's emotion detectors in classrooms would benefit the learning and success rates of students around the world.
