text: Sincerely, STUDENT_NAMEThe technology to read the emotional expression of students in a classroom is valuable because there it can show when someone is getting bored in a class. There are plenty of reasons for why to use this technology. One reason could be that it will detect when a student is bored or is becoming confused. Another reason that it should be used is that it would help inprove the lesson or what is being taught. Also most human communication is non verbal, so then the computers need to understand that.
