For instance, if someone finds out about how a student is feeling, he/she will have "Some trouble describing each facial trait that conveys, happy, worried." With the use of the facial action code in a classroom, a teacher can precisely tell how a students is feeling. According to Dr. Huang, " The software is the latest innovation from prof. He relied on work from psychologists like Dr. Paul Eckman to classiy the six basic emotions." This totally means that Dr. Huang was able to co-operate with some psychologists to precisely identify the different basic emotions. Sometimes students often show some various degrees of expression (like not smiling as broadly). "Using video imagery, the new emotion-recognition software tracks these facial movements." In this case, we can conclude that the new technology can precisely identify a student emotion. For this reason, the use of a Facial Action Coding System should be allowed in a classroom.
