text: The technology to read emotions would greatly change the way students learn. If a teacher used this technology and noticed that all of his students were bored and uninterested, he could alter the lesson plan to make it more fun. Not all students will feel the same, though, which is also where this technology could come in. At the beginning of a school year, perhaps, the teacher could use the technology on the class to see how they feel about the particular subject. Then, the students who are excited about the subject and show interest could be sorted into a class that can be run in a way that makes the class educationally suitable for students who actually want to learn that subject. The students that do not show as much interest, or none at all, could be sorted into a seperate class that makes the subject more fun, but still teaches the same points as the other class.
