text: There are a few ways that this technology is useful. One of these ways is if the Facial Action Coding System can read the individual faces of the classroom and modify the lesson for that particular class. Since the "software can modify the lesson, like an effective human instructor" (paragraph 6) it would give the teacher feedback on how they can teach a lesson better therfore increasing the instrests in students and also could potentially increase test scores. Even though the software could have the potential to do these things I still belive that this software is useless.
