Perceiving whether someone is sad, happy, or angry by the way he turns up his nose or knits his brow comes naturally to humans. Most of us are good at reading faces. Really good, it turns out.

So what happens when computers catch up to us? Recent advances in facial recognition technology could give anyone sporting a future iteration of Google Glass the ability to detect inconsistencies between what someone says (in words) and what that person says (with a facial expression). Technology is surpassing our ability to discern such nuances.

Scientists long believed humans could distinguish six basic emotions: happiness, sadness, fear, anger, surprise, and disgust. But earlier this year, researchers at Ohio State University found that humans are capable of reliably recognizing more than 20 facial expressions and corresponding emotional states—including a vast array of compound emotions like “happy surprise” or “angry fear.” Recognizing tone of voice and identifying facial expressions are tasks in the realm of perception where, traditionally, humans perform better than computers. Or, rather, this used to be the case. As facial recognition software improves, computers are getting the edge. The Ohio State study, when attempted by a facial recognition software program, achieved an accuracy rate on the order of 96.9 percent in the identification of the six basic emotions, and 76.9 percent in the case of the compound emotions. Computers are now adept at figuring out how we feel. Continue reading
