Rate the following essay on its writing, argument, and language skills:
The technology to read students faces tp see how they fell is not useful at all. One reason why it isn't useful is that the look on people's faces don't always tell you how they feel. Another reason why this is not useful is that poeple can use this as a distraction in school. The last reason why this is not useful is that it could be incorrect with the way that a person feels. All three of the reasons why are that

the look on people's faces don't always tell you how they feel, poeple can use this as a distraction in school, it could be incorrect with the way that a person feels.

Firstly the technology could not be useful is that people's faces don't always tell you how they feel. A person with a smile on their face could easily deceive this machince. A person who is good at hiding how they feel could trick this machine. A person could be the happiest person in the world but the picture they took could not prove that fact. A coumputer could not detect hwo a person feels just by looking at a picture.

Secondly this could be used as an distraction in the classroom. Kids could use this to also hurt others by using pictures of when they where having a bad time then making fun of them. teachers could constantly use this to annoy their students. Kids or teachers could also just constantly take pictures of a person to annoy them. If this technology was in a classroom it would be more of an annoyance than a help.

Thirdly the program could end up being wrong about how they feel. A person just has to make a specific face and the computer would just guess how they are feeling. The program can't tell you how that person feels on the inside so there is no point in using it. If you just move your face one diffrent way it could completley change what it says about how you feel.

In conclusion this technology would be invauluable to the classroom and anywhere else. It is a complete waste of time of it doesn't know how the person feels on the insde.
