Abstract: A method for physically displaying and manipulating a communication network through physical objects and an interactive display includes: positioning, on a surface of an interactive display screen, a plurality of physical objects, each representing a node in a communication network; displaying a topography of the communication network including at least a plurality of nodes, where each node represented by a physical object is displayed beneath the respective physical object, and where open communication channels between nodes are visually displayed on the screen; receiving a physical gesture performed by a user between two of the plurality of physical objects; transmitting a signal to one of the physical objects or an access point of the communication network causing manipulation of the communication network based on the physical gesture; and updating the displayed topography of the communication network based on the manipulation of the communication network in real-time.
