Rate the following essay on its writing, argument, and language skills:
In the article "Making Mona Lisa Smile," the author describes how a new technology called the Facial Action Coding System enables computers to identify human emotions. This system has changed the Mona Lisa painting. It has made her smile. It detected that she had a sad emotion and changed it to a smile. Now the question is; should we use this on students in a classroom? This could actually tell teachers of how their students emotions are, because sometime you can't tell someone's emotions.

I don't think we should use this in classrooms on students. I think it would waste valuable time for the teacher to actually teach. Many people like to hide their emotions. The article made a statement about your smile. " They even indicate the difference between a genuine smile and a forced one." Sometimes you feel the need to force a smile. You do it because you know it's the right thing to do. If we detect that that was a false emotion, then it could make many people fell very upset. It could also have many advantages too. It could let the teacher know how students emotions change from a different type of lesson. Maybe the students are more actice to participate during a different type of lesson, so that the teacher knows which way is the best to teach. The Facial Action Coding System has its advantages ,but could also lead to many disadvantages.

The Facial Action Coding System is great piece of technology. I don't think it would be something that is used very much. Dr. Huang said that, "even though individuals often show varying degrees of expression" (like not smiling as broadly). Using video imagery, the new emotion-recognition software tracks these facial movements. The technology invloved in this system is amazing, I just don't think many people would actually take the time to use it.
