text: All of this is assuming the school would even want the technology. It sounds very nifty at a glance, but the idea itself is actually extrememly invasive. Emotions are the secret to what's going on in our brain, all of our deepest thoughts and desires are secretly expressed in our emotions, sometimes very subtley. Kids are very secretive, and would almost certainly not take kindly to having there personal emotions, and by extension, what they are thinking about, out in the open. The author says that this technology in a class room would help recognize when a student becomes "confused or bored," but what about all the other emotions that would come with it: the sadness over a lost loved one, the love a teen is feeling towards their crush. These emotions are deeply personal, and if a child wanted to share them he would tell you. Stealing them away with technology is a clear invasion of privacy.
