阅读理解Faces show emotions. Psychology; puter science, and engineering researchers are joining forces to teach machines to read expressions. If they succeed, your puter 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 municate 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 bination 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.1.People can know a person's emotions from his _____.
