People often reveal their private emotions in tiny, fleeting facial expressions, visible only to a best friend — or to a skilled poker player. Now, computer software is using frame-by-frame video analysis to read subtle muscular changes that flash across our faces in milliseconds, signaling emotions like happiness, sadness and disgust. Or computer-based games with built-in cameras could register how people are reacting to each move in the game and ramp up the pace if they seem bored. But the rapidly developing technology is far from infallible, and it raises many questions about privacy and surveillance. Ever since Darwin, scientists have systematically analyzed facial expressions, finding that many of them are universal. Humans are remarkably consistent in the way their noses wrinkle, say, or their eyebrows move as they experience certain emotions.

Facial expression created with computer keyboard - CodyCross Answers All Levels

A new computer model that can recognize 21 distinct facial expressions more than triples the previous number of documented expressions for different emotions, researchers report. The new program can even pinpoint expressions for complex or seemingly contradictory emotions such as "sadly angry" or "happily disgusted," according to the Ohio State University researchers. They said their achievement will help scientists map emotion in the brain with greater accuracy than before, and could help in the diagnosis and treatment of conditions such as autism and post-traumatic stress disorder. Until now, limits on reading facial expressions restricted scientists to studying six basic emotions : happy, sad, fearful, angry, disgusted and surprised. The researchers created the computer program by taking 5, photos of women and men making faces in response to statements such as, "You just got some great unexpected news" happily surprised , or, "You smell a bad odor" disgusted. Analysis of the facial muscles in the photos enabled the team to identify expressions linked to 21 emotions, according to the study, which was published in this week's issue of the journal Proceedings of the National Academy of Sciences.

Objective: The current study aims to investigate whether computer generated CG expressions of emotion evoke similar emotional appraisal processing in the lateral orbitofrontal cortex lOFC compared to real human expressions, as well as how speech cues would influence the processing. Methods: Functional near-infrared spectroscopy was used to measure the neural activations in the prefrontal cortex during emotion recognition task. Thirty normal participants were asked to view videos of dynamic facial expressions and selected the emotions that were best matches with the expressions. Furthermore, speech cues increased the activation in the lOFC for CG expressions but not real expressions. Conclusion: Comparing to real expressions, CG expressions evoked less appraisal processing related to motivational values although this disadvantage can be compensated to some extent by presenting the expressions with speech cues.
