Abstract: A system is disclosed that enables intelligent environments comprised of physical spaces that sense and respond to the people and events taking place in them to dynamically influence environmental factors that affect them, such as the lighting, temperature, décor or background music. An intelligent environment in accordance with one embodiment of the present invention controls the selection of music played in a fitness center. Two different algorithms are utilized to arbitrate preferences in a shared environment: one seeks to maximize the average satisfaction of the inhabitants, the other seeks to maximize the equitable distribution of satisfaction among the inhabitants. The resultant system is an approach that affords effective environmental control.
