text: Also, in paragraphs 7 and 8, detailed instructions are given on how the machine works and how it can detect fake emotions from real emotions. For example, at the end of paragraph 7, the author states the difference between the muscle movements in a real and fake smile. He then states how the machine looks for the muscle movements and formations of a real smile rather than those of a fake one. Also, in paragraph 8, even more examples of differences in muscle formation are used to show how the technology will in fact work in a classroom environment. The differences between a fake and real smile may seem like an easy task to distinguish in real life, and it may appear to be a problem for a machine. However, the information written by D'Alto from the interview with Dr. Huang show that the machine will have no problem distinguishing a real, genuine happy smile from a fake, intentionally deceiving grin. Therefore, a student could not effectively trick the machine into changing a lesson in a classroom environment.
