New York: Facial expressions might not be reliable indicators of emotion, say, researchers, adding that people should never trust a person’s face.
According to the study, some businesses are even working on technology to determine customer satisfaction through facial expressions.
“The question we really asked is: ‘Can we truly detect emotion from facial articulations?’ And the basic conclusion is, no, you can’t,” said study researcher Aleix Martinez from Ohio State University in the US.
For the findings, the researchers focused on building computer algorithms that analyze facial expressions.
The researchers analyzed the kinetics of muscle movement in the human face and compared those muscle movements with a person’s emotions.
They found that attempts to detect or define emotions based on a person’s facial expressions were almost always wrong.
“Everyone makes different facial expressions based on context and cultural background,” Martinez said. (IANS)\
