text: Lets say you were at school and you were getting bullied or you werent having a good day. You are trying to hide your emotions but your quiet good at it. But the moment you sit down at a computer, it scans your face and it says that you are sad/depressed. The moment the computer reads your face it can alert the teacher and it can tell if the student is enjoying or disliking the class or school in general. Then, when the teacher knows his/her emoiton, he could ask the student why they are feeling this way and if they need to talk. It could make the students feel special and that they dont need to hide there emotions from people and can feel totally comfortable expressing themselves.
