Rate the following essay on its writing, argument, and language skills:
The Facial Action Coding System is a system that enables computers to identify the human emotions. I think this technology to read the emotional expressions of students in a classroom is valuable because in the article it says "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" Which means they can tell what your emotionals is by the movement of the muscles or by the look on your face. Eckman has classified six basic emotions which are happy, surprise, anger, disgust, fear, and sadness and then associated each with your characteristic movement of the facial muscle. If you're mad your orbicularis oris tightens your lips to show anger, your muscles on your face shows the computer what you're feeling. Dr.Huand new system can even identify mixed emotions because each expression is compared against a neutral face. That's why I think Facial Action Coding System is valuble becuase the computer constructs on a 3-D computer model of the face and it can tell mixed emotions and it has six basic emotions, If it can tell a dead person mood it can tell an alive person mood.
