Digital signs (e.g. electronic billboards), as the replacement of traditional static signs (e.g. paper posters), have gained increasing popularity, especially for out-of-home advertising. The pervasiveness of the smartphones makes it possible to implement new interactive signage systems for advertising purpose. A new drag gable cyber-physical broadcast/multicast media system, Smart Signage, is proposed in our previous work. It allows multiples users simultaneously obtaining the displayed content with an intuitive ``dragging" hand gesture. With the increasing number of deployed digital signs, it is possible that there are multiple signs in one location. In this paper, a new approach is proposed using the existing Smart Signage infrastructure to allow smartphones to interact with multiple digital signs in one location. This approach differentiates signs by the orientations of the signage displays, which are measured by smartphone-embedded orientation sensors. A user can interact with the intended sign by simply pointing his/her smartphone at the target signage display. With this new approach, Smart Signage successfully extends from one-to-many interaction to many-to-many interaction.
