Rate the following essay on its writing, argument, and language skills:
When we use facial expressions it lets the person you are directing the expressions to know how we are feeling. We smile because we are happy, we frown because we are sad, we raise our eyebrows because we are shocked or surprised. We use usually identify those pretty well, but a computer can identify them better. I am for the value of using techology to read student's emotional expressions because teachers need to know what bores them or what excites them.

When I first began to read this, I thought how can technology read our emotions? Then it states in paragraph 3 that the process begins when the computer constructs a 3-D computer model of the face. With all 44 major muscles in the model that must move like human muscles. This computer can identify 6 basic emotion: happiness, surprise, anger, disgust, fear, and sadness. With that type of skill, teachers can know what students like and don't like.

Students get easily bored when it comes to school. When they come into the classroom, they don't want to do the homework or the classwork that was given to them. They want something that will entertain them and help them learn at the same time. With this new technology, student's facial expression will be identified when they like or don't like something. Teachers then can change the way the lesson is taught without changing the lesson at all as told in paragraph 6.

This is a new way to change how schools teach. More students would want to come to school and teachers would have an increase in successful students. Knowing what we didn't know is creating more ideas to the future.
