In this research, a smart mechanism to automatically configure the relative locations of clustered intelligent nodes arranged in a grid pattern is introduced. If an intelligent node knows the relative location of more than one neighboring node, its location can be recognized. By studying the feature of the grid structure and the short-range infrared signal communication method between the adjacent nodes, the location of an intelligent node and the location map construction of the whole system are configured automatically at each node. The algorithms in this study are tested by a cross-module image or video display task with modularized and reconfigurable digital surface, a modular Cyber-Physical System platform which has stacked ‘smart modules’ each of which has smart sensing and multimedia node with infra-red transceivers at four corners. Exemplary applications demonstrate the feasibility of the system in its scalability and practicality as well as performance by being applied to various spatially reconfigurable multimedia platforms.
