text: Another con is that the system could malfunction. Since is sends the information and emotion to teacher/parents the teacher could get worried and ask why this student has this emotion but little do they know that there was wrong information sent. Lets say the student his sitting as his desk and the system scanned his face over a multitude of facial moment and it says your sad, but on the inside you are acually fairly happy. Then the teacher could ask you why he or she is sad, and would try to help him out. But little do they know is that he really happy and something went wrong with the system. It would be pointless, there would be no advantage in having this. It would take time out of your day and there could be a whole ordeal about weither your sad or happy.
