A system for selectively communicating promotional information to a person, includes a sensing system, a storage device, a controller, and a projection device. The sensing system measures a detectable feature associated with the person sensed by the sensing system and the storage device stores a plurality of promotional segments. The controller uses the measured detectable feature associated with the person for selecting one of the stored promotional segments and causing the projection device to project to the person at the predetermined location the selected promotional segment. |
