Lead: Every living thing on planet earth has emotions. These emotions have been used since the beginning of time to express the feelings of the people around you. However, these emotions can be decieving. Someone could say they are happy, when really they are angry or upset. This is where the Facial Action Coding System comes into play. The FACS is a software that detects human emotion by tracking muscles in the face. For example, when you are happy, muscles in your face move up, and when you are sad, they move down, FACS tracks this and calculates your emotions. The creators of this software, Prof. Thomas Huang and Prof. Nicu Sebe are the leading experts of developing better ways for humans and computers to communicate. There are still some questions surrounding the usefulness of FACS, like what could this software actually be used for? One of the ways FACS may be used is in classrooms.
