Rate the following essay on its writing, argument, and language skills:
The use of this technology to read the emotional expressions of students in a classroom isn't a good idea. Some students may feel depressed and they probably don't want anyone to know. By using that technology you are exposing that. Although it was for good intentions some people may not feel comfortable with using it. Many people like to hide their emotions and not show it at all.

By having that technology exposed your emotions can also lead to bullying. By bullying that can lead to even more depression or anger. Most schools don't tolerate bullying but that technology is somewhat promoting it even though it has good intentions. I'm sure that alot of people can tell the emotions by looking at them. This also shows that the technology is uncalled for, the can simply ask someone how they're doing and you can tell by that.

In the article it says "In fact, we humans perform this same immpressive "calculation" every-day. For instance, you can probably telll how a friend is felling simply by the look on her face." Instead of wasting money on technology you can simply ask how they are feeling.

There is no use in the technology if you can just ask how are they doing. Alot of people wouldn't even use it. Either because they don't feel comfortable using it or either the don't want people to know how they're feeling which alot of people don't.
