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. Moreover some businesses are even working on technology to determine customer satisfaction through facial expressions. Apparently for the findings, the researchers focused on building computer algorithms that analyse 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 analyse facial expressions.

 

The researchers analysed the kinetics of muscle movement in the human face and compared those muscle movements with a person's emotions. It is also true, that sometimes, For the findings, the researchers focused on building computer algorithms that analyse facial expressions  peoplesmile out of an obligation to the social norms, the researchers said. Perhaps the researchers analysed the kinetics of muscle movement in the human face and compared those muscle movements with a person's emotions.
