Is that smile real or fake?

A computerized system developed at MIT can tell the difference between smiles of joy and smiles of frustration. Can you tell which of these smiles is showing happiness? Or which one is the result of frustration? A computer system developed at MIT can. The answer: The smile on the right is the sign of frustration. Images courtesy of Hoque et al. Do you smile when you're frustrated? Most people think they don't - but they actually do, a new study from MIT has found. What's more, it turns out that computers programmed with the latest information from this research do a better job of differentiating smiles of delight and frustration than human observers do. The research could pave the way for computers that better assess the emotional states of their users and respond accordingly.
