Human Facial Expressions
Mona Lisa: Smiling?
Computer Scientists Develop Software That Evaluates Facial Expressions
August 1, 2006 — Computer vision software can now map a person's face onto a mesh computer model and
calculate facial expressions based on facial points such as lip curvature, eyebrow position, and cheek contraction.
The software detects happiness, disgust, fear, anger, surprise and sadness with 85 percent accuracy, but
researchers don't yet have the technology to detect more subtle emotions.

Consider that the computer might do better than most humans at judging facial expressions. Could a
person plant a camera and use the computer to read the other poker player's facial expressions?
Could police use such a computer during questioning of a suspect? The policeman could say things
like, "You aren't going to fool the computer."
