text: Student Council Leader STUDENT_NAMEIt gets frustrating when a you don't know whether your friend or family member is mad at you or just in a bad mood. Luckily there is way. Thomas Huang, professor from the Advanced Science at the University of Illinos,has invented a Facial Action Coding system that allows you to identify human emotions. Its a great way to stop all the confusion and know if someone is happy to see you. Although its a great tool for everyday life, it's not a great asset in a classrom. Using technology to read the emotional expression of studuents in a classroom is not valuable becausse we should focus on teaching valuable material and its lack of accuracy.
