text: Although this technology sounds great and seems like it has no flaws or problems, it does. The system may become a distraction to the children by them knowing about it and continuing to think about it. The FACS system may also mess up and read the wrong emotions on someone and send the wrong information to whoever runs the system. It is not said how long of a process that it takes just to figure out one persons emotions. Having the system would be better than nothing though. It's better to know how the kids are feeling rather than not knowing at all.
