text: This would be useful to help students stay active and be intrested in what they are going to learn. It would tell us if the student is bored and that could help us find another way to make the kid more intrested in what we are learning. It would also tell us if the kid was slacking off which if a kid was slacking off we could move him and let him be more comforable where he could be more intrested and pay attention to the things he is about to learn. We would be able to help out your child many peoples children we could help them get on track and maybe help them get a scholarship and give them a better understanding of school and education. Would you want your childs emotions read by a computer?
