Rate the following essay on its writing, argument, and language skills:
The use of FACS technology to read student's emotional expressions are valuable. FACS, made by Prof. Thomas Huang and his collague, was made to detect emotions in paintings or in humans. According to Dr.Huang, " facial expressions for each emotion are univesal," which is why the new technology is used to find out what these expressions mean. FACS can detect facial expressions in paintings such as Mona Lisa. The computer can recognize what kind of emotions are expressed in the painting when most people can't. Humans can also perform this action when we look at a family or a friend's face, it is easy to tell how they're feeling by looking at their face. The computer also makes emotions look more realistic in video games. According to Dr. Eckman, the computer has six emotions; happiness, surprise, anger, disgust, fear, and sadness.

Furthermore, when students are in a classroom learning for hours or even minutes, they get bored, confused, or even annoyed. Teachers can sometimes realize that and sometimes they can't which is how the computer can help. Simply by looking at sudents, it reads their emotions and when it realizes learning is not fun for them anymore, it changes things. Accoring to the text, a classroom computer will detect that the students are feeling bored. How the computer helps is by changing how the teacher is teaching the students. It modifies the teaching area to create a new way to teach students.

To end it all, FACS is resourceful for anyone. With the emotions it has, it can easily read people's face and recognize what type of emotions they have. It also helps students and teachers a lot by creating new amusing ways for students to learn. People can't always know what other people are feeling by looking at their face but the computer can. It's an upgrade made by professors and doctors to help society and people.
