text: This technology could also help both students and teachers in a long-term manner. In paragraph 7 of the article, it is revealed that this new technology could "even indicate the difference between a genuine smile and a forced one" (Paragraph 7). Say there is a classroom without an emotion-sensing computer. In the classroom there is a student who, behind the fake smile is dealing with something that they cannot tackle on their own. The teacher never notices, and the child goes on without help. Now imagine if there was a computer in that class. Once it sensed the troubling expressions on the child's face, it could flag down the teacher and alert him or her to the students problem, resulting in the child getting the counceling he or she needs. In an extreme case, this classroom technology could end up saving a life.
