Rate the following essay on its writing, argument, and language skills:
According to the article, I think this technology would be very useful to students in a classroom. The article states "The facial expressions for each emotion are universal." The video imagery tracks these facial movements in a real face or in the painted face of Mona Lisa. Each expression is compared against a neutral face. It also can be identified by mixed emotions.

The classrom computer could recognize when a student is confused or bored. That's not what we notice everyday in life on a computer in class. This computer will be able to recognize our emotions as if we were happy or sad. If we smile, a smiliar ad will appear on our screen but if we are unhappy then the ad will be different. It can modify the lesson like an effective human instructor. The same technology can also make computer-animated faces more expressive! So that could be for video games and also video surgery.

This tecnology will even indicate the difference between a genuine smile and a forced one. Its all about muscular action units. In a real smile the zygomatic major lift the corner of your mouth. But in a false smile, the mouth is stretched sideways using the different muscle, the risorius. Not all computers can just detect our facial expressions just like that. This technology can do just about that!

In conclusion, this technology would be great for students to have in the classroom! Not only will this technology detect their facial expressions but moving your facial muscles can help produce them! This technology would be able to indicate very specific emotions that not us humans would be able to tell what kind of emotion someone else is having. This will show us how technology is getting better and even smarter. How interesting technolgy is getting everyday.
