Rate the following essay on its writing, argument, and language skills:
There's a new software, the Facial Action Coding System, and has promising applications for a variety of industries. It can be able to detect exactly how other people are feeling, even when they try to hide their emotions. I think the use of this technology that reads the emotional expressions of students in a classroom is valuable because it can help teachers know how students are really feeling, not by how they pretend to feel. Students can fake emotions by fake smiling when they're down or students can look sad, but be alright and just not be smiling.

The text states "the process begins when the computer constructs a 3-D computer model of the face, with all 44 major muscles in the model must move like human muscles. Dr Huang relies on the work of psychologists, such as Dr. Paul Eckman, creator of the Facial Action Coding System. Eckman has classified six basic emotions, happiness, surprise, anger, disgust, fear, and sadness. They are associated with characteristic movements of the facial muscles." So the system has most of the emotions that are used in the everday life. When your muscles move it helps determine your emotion a little better. Some examples, are your frontalis pars lateralis muscle raises your eyebrows when you're surprised and your orbicularis oris tightens your lips to show anger.

Secondly, the facial expressions for each emotion are broad and you can see mixed emotions. In the text it said "There's universal emotions even though individuals often show varying degrees of expressions

(like not smiling as broadly). Using video imagery, the new emotion-recognition software tracks these facial movement-in a real face or in the painted face of Mona Lisa. By weighing the different units, the software can even identify mixed emotions. Each expression is compared against a neutral face. " When a person is sad and mad, the video imagery can help figure that out. You may not know why they're mad and sad, but you know how they are feeling and something is going on. Then, maybe a teacher can help the student let their emotions out and open to them on why they're feeling different emotions and what's going to cause them to be the way they are.

In addition, in the text it talked about how humans can calculate other people's expression everyday like being able to tell how a friend is feeling by just looking at their face, but we could have some trouble if their face is worry and other people think they're just tired. In the text, it stated :Dr Huang ovserves that artists such as da Vinci studied human anatomy to help them paint facial muscles precisely enough to convey specific emotions. His new computer software stores similar anatomical information as electronic code. Perhaps Dr Huang's emotion algorithms are a different sort of "Da Vinci Code". So even back then artists could draw people with perfect muscles showing their true emotions like da Vinci with Mona Lisa. The Mona Lisa demonstration is intended to bring a smile to your face to show how much the computer can do. It truly is amazing because technology is so advanced, but this technology you could really get a good use out of it for students in their classrooms, mostly for kids who are quiet and just keep to themselves. The text also stated, "for example if you smile when a Web ad appears on your screen, a similar ad might follow. But if you frown, the next ad will be different. A classroom computer could recognize when a student is becoming confused or bored, Dr Huang predicts. Then it could modify the lesson, like an effective human instructor." It's very helpful for when it shows a student is puzzled on a certain material that is being taught and it can notify the teacher. If the student was shy to ask questions in front of everyone or if they were embarassed to say anything, the teacher woud know and would be able to help the student individually.

Furthermore, the article talked about how moving your muscles helps express your emotions, which is how the Coding system is able to catch onto how you're feeling and if you're hiding your emotions. Examples from the text are, there is an indicator that indicated the difference between a genuine smile and a forced one. "In the real smile, the zygomatic major (muscles that begin at your cheek bones) lift the corners of your mouth. Meanwhile, muscles called orbicularis oculi pars palpabraeus make crow's-feet around your eyes. But in a false smile, the mouth is stretched sideways using the zygomatic major and a different muscle, the risorius. To an expert, faces don't lie; these muscle clues are sometimes used to spot when a "smiling" politician or celebrity isn't being truthful. According to the Facial Feeback Theory of Emotion, moving your facial muscles not only exresses emotions, but also may even help produce them." When faking smiling people can detect it by the way your mouth looks. It's better to just show your true emotions because there may be many people who can tell your true emotions and when you have the technology in classrooms, teachers will be able to tell your mood.

In conclusion, I think the use of the technology that reads the emotional expressions of students in a classroom is valueable. There are many reasons on how it helps and how it works which are several stated above. It's truly amazing techonology and is very advanced and can detect every little thing, like when faking an emotion or having multiple emotions. This will help teachers in their classrooms when a student is confused. Students won't be able to fake their emotions and someone can help when there is sadness that is detected.
