Pandanapper writes to tell us Yahoo is reporting that if you find yourself watching an ad on a video screen in a public venue, the ad may be watching you as well. "Small cameras can now be embedded in the screen or hidden around it, tracking who looks at the screen and for how long. The makers of the tracking systems say the software can determine the viewer's gender, approximate age range and, in some cases, ethnicity -- and can change the ads accordingly. That could mean razor ads for men, cosmetics ads for women and video-game ads for teens."
