Rate the following essay on its writing, argument, and language skills:
The Facial Action Coding System would have value if used in a classroom. Not only would it benifit the teachers, but it would also benifit the students as well. The Facial Action Coding System in a classroom would have positive effects.

Applications of the FACS within a classroom are varied and vast. Just one use of FACS would be a survey. The student or teacher could be shown a video of controversial topics while the FACS would scan them. You would already know their thoughts about it without even asking them. If you wanted to perform a group survey, you could see the difference in their emotions when surrounded by friends and when not. And if the FACS wasn't fully tested, you could survey people and then compare the answers of the FACS and of the person. And even if none of the FACS surveys worked, there is still a chance that the survey subjects could learn more about human emotion. Even the world as a whole could gain from the FACS and learn more about human emotions.

The Facial Action Coding System could also be used on a much broader term. It could be used for online internet use as well. Virtual Reality could be integrated with FACS to create a more accurate representation of a person's face. Not only would that be amazing by itself, but it could also get humanity closer to full-body VR.

The FACS could help students and teachers realize their own emotions better about simple things like homework, or even eachother. A student could be playing an educational game to learn a new language. The student is trying his best, but the question is too hard for him. The camera would see this in his face, and change the difficulty of the question.

Although there are potential flaws with using the FACS technology, the positives completely outweigh the negatives. One potential flaw is that we could end up relying too much on the FACS tech and eventually won't be able to see human emotion by ourselves. This isn't a problem though. If we don't use the technology out of laziness, we will retain our social abilities, like empathy.

If we could have FACS technology integrated into classrooms, the positive possibilities that could open up would be so benificial for mankind, the internet, other students, parents, and even teachers.
