New Technology Records Emotions of Passers-by
German researchers have developed a new tool to recognize emotions as they flicker across the human face. Rapid facial analysis has huge potential for advertisers, but some are concerned about protecting privacy. A small video camera records the face of each person who passes and registers whether the person looks happy, surprised, sad or angry. Complex algorithms find faces in a video image, count the number of people watching an ad, distinguish between men and women and analyze their expressions. Plus, it all happens in real time.
