text: In paragraph three the passage states, "The process begins when the computer constructs a 3-D computer model of the face; all 44 major muscles in the model must move like human muscles. Movement of one or more muscles is called an "action unit." Then Dr. Huang relies on the work of psychologists, such as Dr. Paul Eckman, creator of FACS (Facial Action Coding System). Eckman has classified six basic emotions- happiness, surprise, anger, disgust, fear, and sadness-and then associated each with characteristic movements of the facial muscles." What this can prove is that the process of expression recognization requires no harm to the face or person and is created by the studies of not only technological professionals, but also psychological preoffesionals as well.
