text: However, my claim is that FACS technology shouldn't be used on people. Some people might want to keep some of their emotions to themselves. Most of us would have trouble actually describing each facial trait that conveys happy. For example, when talking about someone or a movie, some people don't want others to know how you really feel because it might hurt their feelings. You wouldn't someone saying they like your new haircut, when the FACS says they felt disgust when they saw your shirt. Peoples' emotions should be kept to themselves.
