text: In the article the author Nick D' Alto talks about Mona Lisa he says "She's 83 percent happy, 9 percent disgusted, 6 percent fearful, and 2 percent angry" (Alto 1). This quote itslef is nerve racking due to the fact that a computer is able to find this information out. Using this type of technology to read students emotional expressions would be helpful but it would not be professional. Honestly who would want to see what a teenager feeling?
