Rate the following essay on its writing, argument, and language skills:
Ever wondered how your peers feel like but don't know, well now you do! Due to new technology by Dr. Paul Eckman, you can now tell how someone is feeling. But is this new technology useful? And is it reliable? Well let me inform you about it.

Is this new technology FACS (Facial Action Coding System) actually useful? Yes it is, what if "A classroom computer could recognize when a student is becoming confused or bored", well as stated in paragraph 6, the computer "... could modify the lesson, like an effective human instructor." This technology could contribute to the teacher, in multiple ways.

Well according to Dr Eckman, he has programmed the system to classify "six basic emotions- happiness, surprise, anger, disgust, fear, and sadness..." These six basic emotions are then "associated each with characteristic movements of the facial muscles". These muscles are Frontalis pars lateralis (above your eyes) which raise your eyebrows when you're surprised; your orbicularis oris (around your mouth) tightens your lips to show anger.

Well now that you no about this new technology, you might be able to figure out how someone is feeling, just by the facial expressions that they show. And yes it is useful, and actually reliable.
