text: First of all i am against using this technology because, In the passage it says Faces dont lie and it can tell when someone is inmatating a fake smile and i dont really think that is true sometimes faces do lie. I honestly think that being able to read student emotion is awsome in all but its kinda personal. i dont think people want other people know about their emotions. i also think that if this technology is used people will probably become addicted to it and it will probably start getting on people nerves. In the passage it states that when a student becomes bored and confused Dr. huang predicts that it could modify the lesson like an effective human instructor.
