Rate the following essay on its writing, argument, and language skills:
Facial Action Coding System allows computers to identify human emotions. Websites could use this technology to keep people interested in ads. Teachers could use this technology to identify the emotions of students in the class. I believe that the use of this new technology, on students, would be an invasion of privacy.

Most students do not want their emotions to be known, especially by a teacher or their classmates. Emotions are meant to be something that is willingly shared by a person, not taken from them by a software. If a teacher believes that a kid is confused or bored, then they should ask the student not a computer. Often an emotion that is felt is not shown on the outside. A person might look completely uninterested, when in reality they just naturally look bored.

The Facial movements do not tell every emotion as it truely is. Some emotions are easily confused while others are an odd combination. A person cannot always show their true emotions plain as day. There are disorders that give people permanant smiles or frowns. Some people naturally look angry or sad. If all emotions were clearly stated by facial movements, then there would be less confusion in the world.

Dr. Huang said that a computer could change a lesson based on the emotions that a student is "expressng." (6) If a student appears confused during a lesson, modifying it for that one student is a terrible idea. Classes are made up of more than just one student. If a lesson is changed because one kid is looking confused, then a few more kids might not understand anymore. It is impractical to try and keep every child interested in a class. If a computer kept changing the lesson because one kid was bored, then the entire class would never learn anything.

Logically, computers that are used to detect emotions in a class and change lessons beased on that are impractical, illogical, and a hinderance to learning. Students can ask a teacher to explain a lesson in a different way, but a teacher will not change an entire lesson based on one student's needs. There are many other resources that schools can use to help kids excell, but invading a child's privacy by analyzing their emotions is not the correct way to go about it.
