text: Driverless cars are going to happen soon. Automakers including Tesla, Mercedes-Benz, Audi, and Nissan are planning on having cars that can drive themselves within the next 4 years. If we have autopilot cars then it would give us a whole new feel on driving. Sometimes change is a good thing. The FACS, or Facial Action Coding System, can recognize emotions. This may allow us to "calculate" emotions like math homework. The computer constructs a 3-D computer model of the face; all 44 major muscle in the model must move like human muscles. Movement of one or more muscle is called an "action unit". Dr. Eckman, creator of FACS, has classified six basic emotions: happiness, suprise, anger, disgust, fear, and sadness, and then associated each with characteristic movements of the facial muscles.
