text: Reading students emotional expressions can determine how they could possibly feel and perhaps help them out if they're feeling low or having a bad day. A simple computer program could tell if a student is in need of help by determining if the student is in a state of confusion or stress. Then if the student is confused or in need of help then the lesson could be modified and altered to be made more understandable for the student. The student could also be helped by a digital instructor that would trigger when the student is confused. Technology like this could give students better understanding of whatever is being taught knowing there are students that are too shy or scared to ask questions it could finally help them learn without having any fear of raising their hand and causing attention.
