text: In conlusion, modern day technology can identify human emotions through a 3D computer or The Facial Action Coding System. The value of using this technology to read students' emotional expressions is very valuable and can be used to express how someone feels. I'm 100% for the use of this technology becuase this is a one of a kind new age technology.Do you ever wonder how it would be if we lived in a car free enviroment where cars where limited. There would not be any traffic jams,or heavy smog,people wont have to worry about gas prices. Our enviroment would be cleaner and better for us to live in. There are so many advantages from limiting car usage.
