Tokyo Rail Billboards Scan Viewer's Age, Gender

eldavojohn writes "The AFP is reporting on digital billboards in Tokyo that scan for a viewer's age and gender to tailor the message to them. It's a Digital Signage Promotion Project that 11 railway companies are debuting. The head of the project said, 'The camera can distinguish a person's sex and approximate age, even if the person only walks by in front of the display, at least if he or she looks at the screen for a second.'
