Disclosed are smart digital modules, a smart digital wall combining the smart digital modules, a context-aware interactive multimedia system, and an operating method thereof. The smart digital wall includes local coordinators for controlling the smart digital modules, and a coordination process for controlling the smart digital modules. The smart digital modules sense ambient states and changes of states and independently display corresponding actuations. The coordination process is connected to the smart digital modules via radio communication, and combines smart digital modules to control collective operations of the smart digital modules.
