text: The FACS system is a new and valuable peice of technology that has many interesting and strong applications. Like it was said im the text, it could adjust an assignment for a student to make it more engaging for them. 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." (D'Alto). That would make teachers lifes easier, and have less annoyed and out of control students, because they would be doing an assignment they would want to do, and not be extremely bored throughout class. Another way this could be valuable is for when cops do lie detector test. They would be able to pick up movements in the face that could show them that they are lying, or not telling the whole story. There are also many real world applications for this technology out there.
