In the our world we are living in, the technology is expanding and is becoming more useful in our daily lives. In addition, the new technologly helps us achieve difficult tasks. The Facial Action Coding System may help teachers in classrooms to better understand the students by knowing their emotions.

In a classroom teachers are expected to communicate with the students. The technology would help read the student emotions, according to the text, "A classroom computer could recognize when a student is becoming confused and bored". By using the students facial movements, the technology reads the students emotion. The use of this technology will help the teachers communicate with the students' emotion.

Secondly, the FACS can help the students and teachers better understand each other in a classroom setting. By knowing each others emotions, allows teh students and the teachers to have an open mind. In the text, "Aclassrooom computer could recognize when a student is becoming condused or bored," Dr. HUang predicts. "Then it could modify the lesson,". This can allow the teachers to 'modify lesson' to help the students understand more fluently.

In conclusion, this technology should be used in a classrom because it will improve the communication and understanding between the students and teachers. Without the FACS, the teachers would struggle to read the emotions of students.
