At least according to some new computer software you can recognize emotions. The software is the least innovation. The process begins when the computer constucts a 3-D computer model of the face all 44 major muscles in the model must move like human muscles. In fact, we humans perfoorm this same impressive ''calculation'' everyday. It could be hard to figure out someones facil expression but using thast software could help you figure out what they are feeling.
