Abstract: A method for controlling an object space having an associated object environment includes the steps of, defining a target set of coordinates in the object space, recognizing the presence of a predetermined object in the object space, and determining a coordinate location of the recognized predetermined object in the object space. The method further includes determining the spatial relationship between the recognized predetermined object and the target set of coordinates, comparing the spatial relationship with predetermined spatial relationship criteria, and if the determined spatial relationship criteria falls within the predetermined spatial relationship criteria, modifying the object space environment.
