text: The use of this technology would be great for teachers to know if their students are confused or bored. The teacher could teach a different way each day and see how the students reacted. Then which ever way kept the students more interested and made them pay attention more would be the way the teacher could start teaching so that the teacher gets the best results from their students. If the students are confused and don't want to ask a question the teacher could see that the student is confused and then the teacher can talk to the student one on one to help the student best understand the topic that he or she is confused with.
