A Display That Tracks Your Movements
 

There could be a revolution brewing in billboard advertising. Instead of simply presenting a static image, why not let people interact with the advertisement? This is the vision of electronics giant Samsung and interactive advertising company Reactrix Systems. The two companies have partnered to bring 57-inch interactive displays to Hilton hotel lobbies by the end of the year. These displays can "see" people standing up to 15 feet away from the screen as they wave their hands to play games, navigate menus, and use maps.
