Rate the following essay on its writing, argument, and language skills:
In the article, facial recognition software called the Facial Action Coding System allows for computers to better understand and identify human emotions. The software was created by Dr. Paul Eckman, who is a psychologist. The FACS technology is used to analyze several muscles upon the face to determine the current emotion of the person or people who are using the software. Many feel like this technology could possibly be used to change up the education system by analyzing the faces of students who appear bored or uninterested in the cirriculum that is being covered. But, the cost to run and maintain the systems that are needed to run the FACS within schools and other facilities may create an issue because it is costly, and not everyone is going to have the funding to put into such a system.

In a classroom, every student is taught the same lesson and given the same lecture in the same exact manner as every student sitting around them. Their faces, just like any other human being, can determine their current emotions towards the subject they are learning or the topic that they are covering. FACS has the ability to analyze all 44 major muscles in the human face, which are responsible for showing emotion every single day. Dr Paul Eckman, a psychologist, created FACS to analyze the facial muscles on the human face and determine the current emotion of someone behind a computer screen. Along with Dr. Eckman, Dr Huang explains how facial exprssions play a role in human emotion, "The facial expressions for each human emotion are universal",oberserves Dr. Huang, "even though individuals show varying degrees of expression" (like not smiling broadly). With the invention of this technology, some feel that it could change the educational system by analyzing the emotions of a student towards the subject they are learning.

In the article, Dr. Huang explains how a classroom computer could analyze the emotions of a student during a lesson or lecture, "a classroom computer could recognize when a student is becoming confused or bored," Dr. Huang predicts. "Then it could modify the lesson, like an effective human instructor." And while this may seem like a good idea, the technology used for FACS cannot be run on a home PC due to the complex algorithims that it uses, and the results may be the same for school computers, which run on similar or less capable software than that of a home PC. This is mentioned in paragraph 7, where it explains the same reasoning why the software cannot be used on a home computer. Another possible issue could come when schools do not have the funding, nor the room for computers in every classroom to adjust the education system. While the technology may be an innovative way to change how students learn, the cost to update compuers, install software, and manage it would be very costly for a school system to continue with doing.

In conclusion, the Facial Action Coding system is a great way to enable computers to communicate more clearly with humans, but may not neccessarily be ready for common use within schools or other places just yet. The algorithms used in the sofrware are too complex for most operating systems used within homes and schools, and may need further development before it is released to the public for common use. In addition, the idea is good for the future, and may change the way the education system works for generations of students to come.
