text: This technology can be used in school to show the emotions of students while they are in class. This could help school directors know wheather a teacher is a good teacher or, well not such good teacher. While calculating the expressions of students in the class students should have a excited and calm expression. Of course there will be that 2% bored out of their mind. But i think many kids should be relaxed at school. This will show the teacher that they understand the lesson and they dont need to reteach it. Lets say that almost more than half the kids are stressing and are showing a worried or bored expression on their face this could mean that the teacher is just not doing enough to help teach the kids. The teacher could also ask if the kids understand and most of them stay quite when confused with the lesson because they are scared of being judged. But now the teacher can know to reteach the lesson or move on with the next.
