Rate the following essay on its writing, argument, and language skills:
This new technology to read the emotional expressions of students in a classroom is valuable.

This technology is valuable because we can actually determine what or how someone is feeling. However making faces can reveal so much about the science of emotions. Alot of us human beings hide our emotions either because of what other people might think or because

you dont want them to feel empathy for you, which is feeling someone else's emotional state. There's also a big lack of human communication. For example, "Most human communication is nonverbal, including emotional communication," notes Dr.Huang."So computers need to understand that too."

Yes i know everyone is like how can we acually calculate our emotions or how can a computer recognize the facial movement that we use to express how we feel. I have prove from the article,"Making Mona Lisa Smile",...all 44 major muscles in the model(face) must move like human muscles." That detects whether its a human or not because of the muscles in our face. Even if we dont have the system just by looking at someone when they are sad there's a frown, when they're happy abviously a smile, etc.

The system and us humans can also tell the difference between a fake and a real meaningful smile. In the cite it states," In the real smile, the zygomatic(muscles that begin at your cheek bones) lift the corners of your mouth." And in a false smile,"..,the mouth is stretched sideways

using the zygomatic major and a different muscle, the risorius." Using this system would really benefit all of us in whether there's no communication then with the system you'll see why.

Another example would be the Mona Lisa Smile theres alot of emotions going on its a pretty confusing picture if you look at the details pretty closely, but just looking at her like this in the painting we see a smile and we just think that she is happy which in reality there's more than that being shown. In the article "Making Mona Lisa Smile", they used the system and these were the results,"she's 83% happy, 9% disgusted, 6% fearful, and 2% angry."

The system will show more than what we human beings believe a human's emotion or how they are feeling, thats why it is valuable.
