text: Having technology constantly viewing ones facial expressions can be pretty unfortunate. The technology can apparently know if someone is happy or sad ("Making Mona Lisa Smile"). If it can tell if someone is happy or sad can it tell if someone is lying? Lets say a female student asks the teacher for permission to use the restroom. Perhaps this teacher is strict and does not allow restroom passes unless necessary. Telling the teacher in front of everyone that she is on her mentrual cycle is embarrassing for younger female students; even more so if the teacher happens to be a male. Now having technology that can pinpoint the fact that this female student does not have to urinate would be classified as a lie. Therefore the teacher would say no knowing she is lying about having to pee. This of course puts the female student in a difficult position; leaving her to feel bad and embarrassed about being caught in a lie. There are two choices now she doesn't go to the restroom and risks staining hersle with blood or she tells the teacher in front of everyone that she is on her period and be embarrassed about that too. Having this technology can be greatly embarrassing for many other students too.
