The use of this technology to read the emotional expressions for students in a classroom can be valuable. When students are having trouble with their assignments it will show the teacher what they are struggling with. Although, some students would not feel comfortable sharing their emotions it can help them with their assignments.

Some people will think that someone is happy when they're really just putting a fake smle on their face."For instance, you can probably tell how a friend is feeling simply by the look on her face." With this new technology you can see how their really feeling.

How you use this technology can show if it's valuable or not. Using it to see if a student is having trouble is valuable, but if you use it just for the fun of it, it's not valuable. "To an expert, faces dont lie; these muscle clues are sometimes used to spot when a smiling politician or celebrity isnt being truthful." The Facial Action Coding System can also be used for criminals. When officers are not sure wether some man is a criminal, he can use this technology to see if the criminal is lying. I think this techonolgy will be useful with students and many other people. I believe reading the emotions of the students in a classroom is valuable.
