We believe that virtual simulation of physical environments is an insuficient basis for building collaborative support systems. In response, we present a locales framework which frames collaboration as the interaction of individuals within social worlds regardless of whether that interaction is physical or virtual. The ovewim describes theJive aspects of the framework: locale foundations, where locales are the basic structures providing the affordunces for the work of social worlds; mutuality in interaction, including presence and awareness issues; individual views of multiple locales of interest, defined by the individual’s participation in multiple social worlds: interaction trajectories, capturing the temporal dimensions of interaction; and civic structures, which embed locales and the collaborative work of groups in the largerpublic sphere.
