text: Lastly, if the physical problems of the technology have not already been offputting, then maybe the moral problem of this technology will sway opinions against using it in a classroom. If this technology really can "indicate the difference between a genuine smile and a forced one", then this means it can invade people's privacy and indicate an emotion which a person is trying to hide. If a student is feeling sad or feeling stressed about home problems which they are trying to conceal, then the technology detects this and displays it for the teacher and the electronic lesson to see. This is an invasion of privacy, as the teacher does not need to know about a student's homelife or about their feelings outside the classroom. A teachers job should be to monitor how their students are feeling about their lessons, not about how their students are feeling about their life outside of school, and since this technology could pick up on digressing feelings, it should not be used in a classroom where a student's internal feelings are revealed to a teacher. Therefore, using Facial Action Coding could end up being an invasion of privacy that should not be introduced to the classroom.
