text: Second reason is that I wouldn't want to pay for it. Some students couldn't afford it. Others could buy it but why would they they are at school to learn not know other peoples emotions. Example what the emotion scanner would do " if you smile when a web ad appears on your screen, a similarad might follow. But if you frowm next ad will be I different." This shows me that you don't need it because all it shows your emotions anwhat kinds ads other sruff that could help you. There's no point for this if it nots helping you with school activities.
