Rate the following essay on its writing, argument, and language skills:
The technology "Facial Action Coding System" to read emotional expressions of students is valuable. I say its valuable because in the text it states "A classroom computer could recognize when a student is becoming confused or bored," Dr. Huabg predicts."Then it could modify the lesson, like an effective human instructor." This tells me that teachers can know if a student does not want to work or is honestly confused while the teacher can provide more help for the student and can make the subject more fun or interesting without the student letting the teacher know. Another reason according to the text is " Yet Dr. Huang observes that artists such as da Vinci studied human anatomy to help them paint facial muscles precisely enough to convey specific emotions." This shows me they can paint facial muscles so they can have enough to know specific emotions to one another. This is why I actually think it will be an good idea for people, it can help people emotionally, it can help someone who is nervous and does not like to express it.
