The software has many potential uses, such as detecting whether drivers are too tired, enhancing law enforcement interrogations, or analyzing pain levels in pediatric patients. However, any application—particularly commercial use without consent—has obvious privacy concerns. After all, is there anything more invasive than spying on our deepest feelings? Some retailers are already developing programs for using security camera footage to analyze customers’ true reactions to products on display.
Today the technology is mostly used to gauge consumers’ emotions as they react to advertisements or try new products. Companies such as Emotient Inc., Affectiva Inc. and Eyeris sell software to marketers who use the systems to measure consumer engagement. The companies gathered massive amounts of data to train their software’s algorithms. They recorded millions of faces of people from various cultures and ethnicities and extracted billions of data points from each frame. Facial expressions are then sorted by emotional categories and used by the algorithm to interpret the emotions of people in videos. Several competing startups share a goal of embedding their software into tiny cameras so they can be used in video chats.
Doctor Paul Ekman, an 80-year-old psychologist whose research and Facial Action Coding System are the foundation for facial recognition software, told the Wallstreet Journal, “I can’t control usage. I can only be certain that what I’m providing is at least an accurate depiction of when someone is concealing emotion.”
