Arguing whether the use of the techonology to read the emotional expressions of stuidents is good idea and is it great techonology they have invented because now you can see how other people really feel and you would not think wrong, another thing is you can also tell how the other person feel about you. Even though i think this is a great idea, some people may not like it and feel offend by this idea because no technology or computer could tell how a person is really feeling. No techonolgy is hundread percent correct.
