The use of this technology to read the emotional expression of students in a classroom is valuable because everyday you can tell how the person in a class is feeling. In the article it says," In fact, we human perform this same impressive "calculation" every day. For instance, you can probably tell ow a friend is feeling simply by look on her face." Dr. Paul Beckman is a psychologist who created FA ACS (Facial Action Coding System.)

So computers need to understand that, too."
