text: In conclusion there are benefits without a car. Benefits for the world around us, and well you might get some stress out if you start walking, hiking, or riding bycicles for a while. It's incredible just to think of the idea that many countries have stopped driving for a day to make their country or city a better place. While in cities like Vauban, Germany people live without cars. Thats what makes their city different. Even though they do also let these things happen for a right cause. I think that we could live without a car for one day, it's not a big deal, really. It's to make the US a better place.    A new source of technology haas been invented that has the power to enable computers to indentify human emotions. This is called the Facial Action Coding System. The first step of the computer is to construct a 3-D computer model of the persons face. This includes all 44 muscles on a human's face as well. They must move exactly as if they were human muscles for the experiment to work. Six emotions have been classified by the model that are the most common expressions of a person in their daily life. These would be happiness, surprise, anger, disgust, fear, and sadness. These are all also associated with each and every movement of the facial muscles. The new created technology seems to be valuable to the people that use it today and specifically would have a value for students in a classroom.
