Overall, safety becomes the first priority, there is still some work that needs to be done.            This technology to read the emotional expressions of students in a classroom is valuable because what if you wan't to joke around with a friend you don't know if they're sad. If they're sad then you can make them laugh. It would be great if classrooms had this technology because in paragraph 6 sentence 5 it says "A classroom computer could recognize when a student is becoming confused or bored", it could show the teachers how to help the students learn the subject without making them bored or confused. In paragraph 6 sentence 6 it says "Then it could modify the lesson, like an effective human instructor", what it's trying to say is that it could make the lesson more interesting than what a human normally would do.
