A cellular automata-based modular lighting system

The term Ambient Intelligence refers to environments enhanced by the presence of electronic devices that are sensitive and responsive to the presence of people. The scenario described in the paper envisages an environment endowed with a set of sensors (to perceive humans or other physical entities), interacting with a set of actuators (lights) that adjust their state of illumination in an attempt to improve the overall experience of these users. The model for the interaction and action of sensors and actuators is an asynchronous Cellular Automata (CA) supporting a self-organization of the system as a response to the presence and movements of people inside it. The paper will introduce the model as well as its implementation in a specific hardware component supporting the realization of modular adaptive lighting systems.
