text: Driving is a big part of our world today, but we have some people and even countries who have to or choose to do it by foot. Its proven to help the mind  and also proven to help with our environment and our safety life. Pollution fills the air but so does the people, making the world a better place to live and causing less stress to the citizens that do so.            Emotions are what you feel on a daily basis sometimes you can be happy and something you can be sad. In this passage "Making Mona Lisa Smile" students from the University of Illinois collaborated with Prof. Nicu Sebe from the University of Amsterdam. They developed better ways for humans and computers to communicate. The technology to read emotional expressions of students in a classroom is valuable because it can how how the student is feeling and it can help see if the student is enjoying what it is learning.
