text: The computer makes a 3-D model face of a human and have all 44 major musles that operates like human musles, then it scans the face of a real human which will then identify what the person is feeling right now such as happy, sad, tired, scared and many more. Using this type of technology will be very helpful in classrooms because when a student is feeling bored or tired then the computer will be able to detect that the the teacher will be able to make the topic more interesting for the students. Most teachers have about 28 students per class for seven periods everyday which can be very stressful, so it can be very challenging for them to recognize when students are dealing with a certain type of emotion but with the FACS it can recognize that and the teacher will be able to help the student or students.
