text: Finally, I think it would be a good idea because the teachers would know how the students are feeling by something they had said or asign. If I was a student, I'd like it cause that would be a good new expreince. Students would not be happy that a machine reads your face to tell a teacher how your feeling. Sometimes people want to be left alone because they are sad or mad. So having this machine woud not be good to have because some teacher could be nosy and ask why are you mad or sad. The machine cold also tell if your lying.
