Rate the following essay on its writing, argument, and language skills:
Imagine if your online school computer could analize if you are understanding your lesson on exponents or not? This could one day be possible. Prof. Thomas Huang and his collegue Prof. Nicu Sebe, are working on a new software that can recogize your emotions. It may know if your happy or sad and by knowing how you feel it will read how you feel about the subject. This technology would be of an imense help in virtual classrooms. This technology could also analyse pictures and videos taken before to see how the person feels while at a public event, or in a old family picture.This technology could help many fields including the advertising industry, as it could tell how you feel from different ads, and change the type of ads you see as suggested by your reaction to them.

However how would the computer know if we are happy or sad? "The process begins when the computer constructs a 3-D model of all the face". In the 3-D model our muscles are copied exactly and the computer analyzes how we feel based on our expression. As if it scaned your face at a family reunion where you don't to be there, but your smiling for the picture. How does it know if your smiling for real, or if your smiling so you don't apear bored in the picture? " In a false smile, the mouth is streached sideways using the zygomatic major and a different muscle, the risorius... these muscle clues are sometimes used to spot when a "smiling" politician or celebrity isn't being truthful."

In conclusion Prof. Thomas Huang and Prof. Nicu Sebe new technology is a inovation that could help many different fields in many different ways. It would help people really see how people feel about a certain topic or person. It could help stores know when a person is mad or annoyed at their products or staff. This new technology would be a great partner with facial recognition working side by side to know how each person feels. This new technology would be important to an online classroom as with an online course you never really truly

understand if a person is frustuated with the material, or if a person really feels motivated and understands what they are being taught. This New technology would be a great addition to the teaching field, and would help students learn to their fullest potential.
