![]() There’s no way you can determine those things. “What our research showed is that those claims are complete baloney. “Some claim they can detect whether someone is guilty of a crime or not, or whether a student is paying attention in class, or whether a customer is satisfied after a purchase,” he said. ![]() The research group that presented at AAAS analyzed some of those technologies and, Martinez said, largely found them lacking. This would not inherently be a problem, he said - people are certainly entitled to put on a smile for the rest of the world - but some companies have begun developing technology to recognize facial muscle movements and assign emotion or intent to those movements. It is also true, Martinez said, that sometimes, people smile out of an obligation to the social norms. And if you are happy for a whole day, you don’t go walking down the street with a smile on your face. I would even go to the extreme of saying most people who do not smile are not necessarily unhappy. “And it’s important to realize that not everyone who smiles is happy. “Everyone makes different facial expressions based on context and cultural background,” Martinez said. They found that attempts to detect or define emotions based on a person’s facial expressions were almost always wrong. The researchers analyzed the kinetics of muscle movement in the human face and compared those muscle movements with a person’s emotions. 16, 2020) at the annual meeting of the American Association for the Advancement of Science in Seattle. Martinez, whose work has focused on building computer algorithms that analyze facial expressions, and his colleagues presented their findings today (Feb. “And the basic conclusion is, no, you can’t.” “The question we really asked is: ‘Can we truly detect emotion from facial articulations?’” said Aleix Martinez, a professor of electrical and computer engineering at The Ohio State University. In fact, it might be more accurate to say we should never trust a person’s face, new research suggests. ![]() Some businesses are even working on technology to determine customer satisfaction through facial expressions.īut facial expressions might not be reliable indicators of emotion, research indicates. We think a frown shows sadness, and maybe we attempt to cheer that person up. We think a smile conveys happiness, so we offer a smile in return. Interacting with other people is almost always a game of reading cues and volleying back.
