text: The FACS uses facial movents to determine whether a person is feeling happy, sad, surpised, angry, disgusted, fearful, or sad. The interesting thing about the FACS is that it can determine whether the person is faking an emotion. For example, the article stated," But in a false smile, the mouth is stretched sideways using the zygomatic major and a different muscle, the risorius". So by examining muscle movements in the face, the FACS can determine whether the person is faking an emotion or actually feeling it. In the future I think therapist could use the FACS to help determine how his/her patent is actually feeling. Dr. Huang stated," A classroom computer could recognize when a student is becoming confused or bored," Dr. Huang predicts."Then it could modify the lesson, like an effective human instructor". I think that this would be an effective way to futher advance eduction in our society.
