text: but the logic is right before our eyes. In the text the author states how the technology performs the task of reading emotional appeals. For example, in paragraph 3 line 1 the author says,"The process begins when the com puter 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". So apparently this process goes beyond just looking at the face,but actually looking for the movements in facial muscles. The author also talks about the muscles that present certain emotions such as the ; the muscles above your eyes (frontalis oars lateralis) raise when you're surprised,the muscles around your mouth (orbicularis oris) tightens your lips when you're angry, and more. This shows that the computer breaks facial expressions down to a science.
