Candid Camera: Facial Analysis In The Wild When a shopper enters Reebok’s flagship store in New York City, a face-detection system analyzes 10 to 20 frames per second to build a profile of the potential customer. The algorithms can determine a shopper’s gender and age range as well as behavioral and emotional cues, such as interest in a given display (it tracks glances and the amount of time spent standing in one place). Reebok installed the system, called Cara, in May 2013; other companies are following suit. Tesco recently unveiled a technology in the U.K. that triggers digital ads at gas stations tailored to the viewer’s age and gender. Face detection shouldn’t be confused with facial recognition. Cara extracts data from up to 25 faces at once, but it doesn’t record or match them against a database. “The images are destroyed within a fraction of a second,” says Jason Sosa, the CEO of New York–based IMRSV, which developed the software. Most businesses aren’t interested in collecting your face, just the demographic info etched into it.

How long will it take before ad companies see the potential in tracking your faces? Some Minority Report shit that is.

I doubt businesses aren't interested. If it can help you buy more stuff, they're always interested.
