By analyzing the movement of the smile across a person’s face, the software developed by researchers at the University of Bradford can determine whether or not the expression is true. The most significant movements detected by the software were around the eyes, supporting popular theories that a true smile is one that can be seen in a person’s eyes.
“A smile is perhaps the most common of facial expressions and is a powerful way of signaling positive emotions (情绪)” says Hassan Ugail, Professor of Visual Computing at the University of Bradford, who led the research. “Techniques for analyzing human facial expressions have advanced a lot in recent years but distinguishing between true and false smiles remains a challenge because humans are not good at picking up the relevant messages.”
The software works by first mapping a person's face from within a video recording, and identifying the mouth, cheeks and eyes of the subject. It then measures how they move through the progress of the smile and calculates the differences in movement between the video pieces showing true and false smiles. They found significant differences in the way the subjects' mouths and cheeks moved when comparing the true and the false expressions. The movements around the subjects’ eyes, however, showed the most striking difference, with true smiles producing at least 10 percent more movement in these muscles (肌肉).
“We use two main sets of muscles when we smile — the zygomaticus major, which is responsible for the movements upwards of the mouth and the orbicularis oculi which causes movements around our eyes,” explains Professor Ugail. In false smiles it is often only the mouth muscles that move but, as humans we often don’t spot the lack of movement around the eyes.
He adds, “An objective way of analyzing whether or not a smile is true could help us develop improved interactions (互动) between computers and humans. It could also be important to scientists aiming to gain more understanding into human behavior and emotion.”
1.Why is it hard for humans to recognize a false smile?
A.Humans are good at hiding their smiles.
B.The relevant details are hard to catch for our eyes.
C.Humans often put on too many facial expressions.
D.Techniques for analyzing facial expressions are hard to develop.

D.True smiles are a powerful way of signaling positive emotions.
3.What can we infer from Professor Hassan Ugail?
A.There are different sets of muscles on every human’s face.
B.The software can improve humans’ behavior and emotion.
C.Humans can spot the movement around the eyes in true smiles.
D.The interactions between computers and humans remain to be improved.

Perhaps the most famous theory, the study of body movement, was suggested by Professor
Ray Birdwhistell. He believe3s that physical appearance is often culturally programmed. In other
words, we learn our looks--- we are not born with them.A baby has generally informed face features. A baby, according to Birdwhistell, learns where to set the eyebrows by looking at those
around- family and friends. This helps explain why the people of some areas of the UNITED States look so much alike, new Englanders or Southerners have certain common face features that can not be explained by genetics (遗传学). The exact shape of the mouth is not set at birth it is learned after. In fact the final mouth shape is not formed until well after new teeth are set. For many this can be well into grown-ups. A husband and wife together for a long time often come to look somewhat alike. We learn our looks from those around us. This is perhaps why in a single country there are areas where people smile more than those in other areas. In the US for example the south is the part of the country where the people smile most frequently. In New England they smile less and in the western part of New York States still less. Many southerners find cities such as New York cold and unfriendly partly because people in Madison Avenue smile less than people on Peachtree Street in Atlanta Georgia. People in largely populated areas also smile and greet each other in public less than people in small towns do.
