Billboard Scans Faces of Passers-By, Shows Ads Only to Women

A digital billboard at a bus stop on London’s busy Oxford Street has a built-in HD camera that scans the faces of people waiting nearby and shows ads only to women. The camera analyzes the facial features of pedestrians, like the shape of the jaw, the distance between the eyes and the width of the nose, to determine which subjects are female. When it determines a female is watching, it shows an ad called “Choices for Girls” that aims to raise awareness of the lack of educational opportunities available to females in developing countries. Men only see a web link to a charity’s official website.
