I think the use of this in a classroom is going to workout great for the students and the teachers. If you have the Face Action Coding System in the classroom the teachers can scan the faces of there students will the teacher is teaching them a lesson. After it scans the faces of the students the teacher can then see if the students are enjoying the lesson or if they aren't enjoying. This could change the way teachers teach kids by doing stuff creative different days so the kids will enjoy what they are being taught. Instead of being upset about what they are learning.
