"The Human Locator analyses a camera feed in real time, sending detailed information about people's location, size, and movements. This data is then used as input to control projections, video, graphic animations, and sound on window displays, inside shops or on public signage." Which probably means you can now show separate ads targeted to tall women or fat men. Or show more info to those who stop by and look at the billboard.
