This computer system can help teachers improve the way they teach their classrooms by analazing students' emotional expressions towards a certain lesson. It can help teachers by modifying their lessons in sich a way so that students are not bored or confused by it. Lastly, it can help teachers know which students may be going through hard times and help those who need help.              If people would stop using cars places would'nt be that dirty in the air it's polluting the air and it wouldn't be that dirty. An example would be in a german suburb people kind of stop using cars and started to walk and use bikes. People would be more healthy and active if cars didn't exist. For me I don't like cars in general. But yeah people praise cars just because they are lazy and like using cars to get places faster. Also people waist a lot of money for a car that would last along three years. Like it says in article 1,paragragh 3 "as a result, 70 percent of Vauban's families do not own cars...". Which means that those families do not own cars because they like to walk or use bikes.
