text: Classrooms contain various emotions, including anywhere from sadness to rage. According to D'Alto, "...the software can even identify mixed emotions..." That can be very valuable for classrooms so the software can read whether the student may be upset and confused, or bored and uninterested. Once the teacher gets ahold of that information then they will be able to help the student and tend to them by their needs. If a student is confused then the teacher will be more likely to be sympathetic and helpful, while if a student is bored then the teacher might give them more challenging work. Although some people may think that the Facial Action Coding System is a phony, it is proven to be otherwise. In fact, it is very well developed and the article states, "The process begins when the computer constructs a 3-D computer model of the face; all 44 major muscles in the model must move like human muscles." Not only has this software been tested many times, it has been constructed so it can read facial muscles and destinguish the emotions well.
