text: There are very few benefits, there is no relevance for knowing the emotions of students, and any emotions of a person may not want to be detected, therefore The Facial Action Coding System is not valuable. Technology is supposed to be beneficial to humans and make life easier. The Facial Action Coding System does the opposite of that. Emotions should be revealed through a person's own wish, not through a computer. This could make many people very angry, due to the programming of this technology. The goal behind The Facial Action Coding System may be to read emotional expressions, but the emotions created, by people, from being able to do so could become very upsetting.
