text: There is lots of value in adding this to the learning experience. For example a computer could adjust the lesson by seeing the look on your face. It can do this since the F.A.C.S. system can quantify the muscles behind human emotion giving an accurate representation of what the person is feeling. If a student is happy with the lesson the system could be used to shorten this lesson since the student likely already knows it and if the student is confused or disgusted by the lesson the program can continue it till they are satisfied with their skills in it and have learned what is neccessary.
