text: Using this techonolgy ti read emotional expressions of student in the classroom it is valuable because when a students is feeling down or depress you would know so you could help them. Another things not much students are going to like this becuase some poeple don't like to tell people how they really feel. They don't like public to know. So it will be embrasse to them. I think using a computer to read poeple emotional would not work on everybody it's not like everyone is willing to tell the public their problem or anything.
