text: The idea of being able to find out the emotions of all of the chidlren in a school on a whim also rises privacy concerns that would need to be addressed before any program including this software would be implemented. The information gathered from students could be used for selfish purposes, as explained in the sixth passage of the article, "if you smile when a Web ad appears on your screen, a similar ad might follow. But if you frown, the next ad will be different," showing that companies have use for this technology to better their businesses. If ad companies managed to get this emotional information from students all across the country, either from the government itself or through illegal actions, they could use that information to make new products and ads that would try to exploit the emotions of children. Because of this and the added concern of giving the information to the government itself, many parents would oppose a system that tracks and records the emotions of children.
