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 is valuable because in the passage it states "Eckman has classified six basic emotions happiness, surprise, anger ,disgust, fear and sadness" based off this piece of evidence the computer that he has designed to detect your emotion will determine how the student is feeling like for example : the sudent is smiling but the smile she has might have a little sadness in her) so the computer can detect that it was a fake smile. Another piece of evidence from the article is "she's 83 percent happy, 9 percent disgusted, 6 percent fearful, and 2 percent angry." based off that statement you can already tell that the technique Dr.Huang created works.

Finally in the passage it states "if you smile when a Web ad appears on your screen, a smiliar ad might follow. But if you frown, the next ad will be different." based on that statement if you smile while your lookig into the computer the next ad will be something about happiness but, if you frown while your looking into the computer then the next ad will be something about sadness.

In conclusion, Dr.Huang's studies and experiment's has been a success because it worked on telling how Mona Lisa was feeling and her emotions. It would be valuable to the students in a classroom.
