Rate the following essay on its writing, argument, and language skills:
Technology has advanced enough for a computer to recognize a person's emotions just by watching their facial features, one such invention is the Facial Action Coding System. If that is the only way to recognize a person's true feeling then one might as well use their own eyes. Of course, our eyes are not always inept to specific details, which a computer will help advance, but if recognizing a one's emotions in the classroom is important, one should just learn the specifics of reading emotions to surely understand what a student is feeling.

If one's emotions in the class room are plainly obvious to a computer, then they should be easily recognizable by the teacher. The passage states, "the facial expressions for each emotion are universal, even thorugh individuals ofter show varying degrees of expressions." With that in mind, students should show a clear expression, such as when one is bored or confused, that is recognizeable to everyone around them, including the teacher, making the the Facial Action Coding System an irrelevance.

The Facial Action Coding system may also be flawed when recognizing emotionaless expressions. When analyzing a person's facial expression, "each expression is compared against a neutral face (showing no emotion)." Which means that the computer will not be able to read a person's emotions if they hold a straight face. In this case, the recognization ablilities of a computer is unnecessary, for in order to recognize that individual's emotions, another person must know how that individual expresses their emotions such as their actions or words. However, the passage states that "most of us would have trouble actually describing each facial trait that conveys happy, worried, etc." In other words, the Facial Action Coding System is helpful when our eyes fail to decifer a stranger's emotions. On the contrary, in a classroom, a teacher should gradually and instincively, learn to recognize the emotions of his or her students without the use of a computer.

Recognizing a student's emotions cannot be solved due to the development of facial recognition systems, such as the Facial Action Coding System. In order to read a student's emotion, it is necessary to understand the student's personal expressions or actions that come from certain emotions. Although a computer can recognize these expressions, it cannot not always be useful if one's expression contradicts the normal facial expression, or an expression is not even shown on their face. Nevertheless, it is not necessary to use a computer to recognize a person's emotions, for it takes a person to know a person, even without a computer.
