text: Going to school can be stressful, tiring, and boring. With the help of FACS, a teacher can recognize when a student is feeling any of those emotions, and change how he or she is teaching a lesson. "A classroom computer could recognize when a student is becoming confused or bored." When FACS notifies the teacher that a student is bored, tired, or confused it can be a cue to either change the lesson, or see if the student needs extra help on any material.
