Rate the following essay on its writing, argument, and language skills:
You're walking into a classroom seeing different faces, different attitudes, and different emotions. Do you think you'll be able to tell the emotion of each student? What if you were sitting in a classroom? Do you believe a computer or any technology that's able to read you and your classmates emotional expresionsis valuabe? If you do, then I disagree.

I believe the use of technology that's able to read the emotional expressions of students isn't valuable.First, I believe this because the software is able to show only six emotions. In the article, it states, "Eckman has classified six basic emotions - happiness, surprise, anger, disgust, fear, and sadness," This shows that emotions like empty or basic won't be shown. If these emotions aren't shown, then what would the system show for an empty-feeling person.

Next, I believe this system isn't valuable because some people can have deceiving faces. In the article, the author, D'Alto says, "...and then associated each with characteristic movements of the facial muscles." This shows that the system is using people's facial expression to tell their emotion. A student can have a bored look on their face, but be very interested in what's going on at the same time. Therefore, the system will believe the student is bored, even though the student is far from it.

Finally, I believe this system isn't valuable because no mater what emotion a person is feeling, some people just have a natural neutral face. In the fourth paragraph it says, "Each expression is comapred against a neutral face." This shows that when a person has a neutral face they're only showing no emotion. Even though a person shows no emotion, deep down inside they might be happy or sad without anyone knowing.

This is why I believe the Facial Action Coding Sysytem is not valuable at all. The system is only able to show basic emotions. The system can't detect deceiving faces. This system clarifies the neutral face as no emotion. I hope you agree.
