text: To students it would almost be like having a teacher in the room instead of a computer. Having technology read emotional expressions is valuable because it would be able to read facial featchers better than a human. It would be able to know if you happy if you raise your lips at the corners of your mouth or squint your eyes slightly, to produce wrinkling at the corners of your eyes. The technology can even see more than more emotion like in the Mona Lisa. Paragraph one line one states "Shes 83 percent happy, 9 percent disgusted, 6 percent fearful, and 2 percent angry."
