text: This technology can be useful in any situation. People don't always share their emotion out loud. We are forced to see how people are feeling simply by their facial expressions, which is sometimes hard to read. Often times people will hide thier emotons by forcing an opposite facial expression for the pleasure of someone else. Wouldn't it just be eaiser to have something that did it for you? " Most of us would have trouble actually describing each facial trait that conveys happy, worried. ect." People are forced to read others emotion by their facial expressions which is one of the hardest things to do.
