text: I can also relate to how the computer could tell if you are confused and change the lesson so you can learn the way you do. In the text it states the computer can tell if you have a fake or forced smile or a guinine smile by the rincles under your eyes. The text also said you can probly tell what mood your friend is by the look on their face,but the person could be hiding their true emotions from you so the computer can tell if you are mad at that person at that time and place.
