text: Everyone has their own opinion in the use of technology based on facial expressions. In my opinion, I believe reading emotional expressions of students in a classroom is valuable. This can be taught as if you we're being instructed by math. You may be thinking to yourself "How can this be possible for a computer to be recognized by a facial expression?" According to the passage, the computer process begins using a 3-D computer model of the face. The appromixate number of 44 muscles must move just like a human. A man, Dr. Paul Eckman created six different emotions such as, happy, surprised, angry, sad, fear, and disgust. Then each characteristic would be assocaiated by the moventment of the facial muscles.
