Rate the following essay on its writing, argument, and language skills:
How many different emotions have you ever felt in your life? You cannot possibly know and remember every feeling you've ever had. Using the Facial Action Coding System is a great idea and an amazing thing that has been developed, however, there is no way it is accurate. The Facial Action Coding System is not accurate because everyone has different facial structures, this system could not possibly know the structure of everyones face, could not detect all emotions, and cannot tell an emotion by the way people look.

Though the face has the same muscles and bones in it, everyone has a different facial structure. Some peoples eyes are far apart, and some are closer together. Some people have more round faces, and others have more square shaped faces. The text states "Meanwhile, muscles called orbicularis oculi palpabraeus make crow's-feet around your eyes. But in a fake smile, the mouth is stretched sideways using the zygomatic major and a different muscle, the risorius.", but some people may not get crow's-feet around thier eyes, and some peoples mouths may not stretch sideways like this. There are many other differences in peoples faceial structures, aside from these examples.

All people feel different emotions in their life. They can also feel multiple emotions at one time. Saying that a face coding system can detect all your emotions is absurd. People have been known to feel exitement, while feeling resentment, and all other combinations of emotions. Technology today doesn't have any way of recognizing all emotions of everyone. The passage says, "Eckman has classified six basic emotions- happiness, surprise, anger, disgust, fear, and sadness- and then associated each with characteristic movements of the facial muscles." It is not hard to guess that humans are capable of feeling more than just six emotions alone or at the same time. This would mean that the recognizing emotons part of this system is inaccurate.

Acting and looking different than how you feel is an excellent way to hide your emotions. People do this almost on a daily basis. "For instance, you can probably tell how a friend is feeling simply by the look on her face." Although this may be true some of the time, even smiling to hide a frown cannot always be dected by a friend. Unless clearly obvious, hiding emotions cannot easily be found. This adds to the previous reason of why the Facial Action Coding System would be inaccurate.

The Facial Action Coding System is not accurate because everyone has different facial structures, this system could not possibly know the structure of everyones face, could not detect all emotions, and cannot tell an emotion by the way people look. In conclusion, this system could be highly inaccurate and ineffective. Perhaps sometime in the future, when technology is much more developed, this system may work a little better, but it will still take many years to perfect the Facial Action Coding System.
