mingrassia writes "Over at CNN: New technology tracks consumer movement, flashes messages and calls out to passersby. Meet the Human Locator. It's a new technology developed by Canadian ad agency Freeset Interactive that purports to detect when humans are near, track their movement, and then broadcast messages directed at them on a nearby screen. Conspiracy theorists can relax, however. The Human Locator can't yet identify, say, obese pedestrians and then bombard them with images of a cheeseburger and fries."
