text: I think it is a great idea to use this technology in the classrooms because it can tell between a real and fake smile. This could help the teachers to understand what the students enjoy so they stay ingaged in class. If a student is fake smiling at a teacher that means they don't like what they are talking about or don't understand. They could also tell if students are talking to other students during class. Then teachers could stop them from talking and all the students around them would be able to listen to the teacher rather then be distracted by the students.
