Faces show emotions. Psychology; computer science, and engineering researchers are joining forces to teach machines to read expressions. If they succeed, your computer may one day "read" your mood and cooperate. Machines equipped with emotional skills could also be used in teaching , robotics, gaming, security, and for psychological diagnoses(诊断).
"Mind Reader", a system developed by Rosalind Picard at the Massachusetts Institute of Technology in the US, uses input from a video camera to do real-time analysis of facial expressions. It reports on whether you seem "interested" or “agreeable” or if you're "confused".
The system can help people detect others' emotions. Picard says this means we could teach a machine to be as sensitive as a human. In fact, a machine can be even smarter: than people since it can tell if a person is lying or just "performing" by analyzing one's facial movements. Jeffrey Cohn, a psychologist at the University of Pittsburgh, uses the Facial Action Coding System to detect human emotions. "The face is always visible," Cohn says, "People communicate a lot about feelings and thoughts through facial expression."
Cohn studied a videotape of criminal who professed to be sad about the murder of several family members and tried to pin the blame on some one else． But Cohn saw no real sadness in the woman's face. Sadness is a combination of facial action units that are difficult to do voluntarily. This means, even though your mouth lies, your face doesn't, and the machine will know it all.

Facial expressions carry meaning that is determined by situations and relationships. For example, in American culture the smile is in general an expression of pleasure. Yet it also has other uses. A woman’s smile at a police officer does not carry the same meaning as the smile she gives to a young child. A smile may show love or politeness. It can also hide true feelings. It often causes confusion (困惑) across cultures. For example, many people in Russia consider smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in public places (although this is less common in big cities). Some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don’t smile enough. In Southeast Asian cultures, a smile is frequently used to cover painful feelings. Vietnamese people may tell a sad story but end the story with a smile.
Our faces show emotions (情感), but we should not attempt to “read” people from another culture as we would “read” someone from our own culture. The fact that members of one culture do not express their emotions as openly as do members of another does not mean that they do not experience emotions. Rather, there are cultural differences in the amount of facial expressiveness permitted. For example, in public and in formal situations many Japanese do not show their emotions as freely as Americans do. When with friends, Japanese and Americans seem to show their emotions similarly.
It is difficult to generalize about Americans and facial expressiveness because of personal and cultural backgrounds in the United States. People from certain cultural backgrounds in the United States seem to be more facially expressive than others. The key is to try not to judge people whose ways of showing emotion are different. If we judge according to our own cultural habits, we may make the mistake of “reading” the other person incorrectly.
