Reflecting on Several Metaphors for Media Spaces

• a bounded space that affords partitioning into a collection of rooms; • containment within through individual rooms, where they collect people and groupware objects; • permeability of rooms allowing people and things to enter and leave them; • persistence of objects within the room over time; • socially mediated ownership that controls who should enter and use that room and how privacy is managed; • customization of that room by how its occupants create and manipulate objects within it; • spatial location where objects and people within a room are spatially positioned in a way that maintains common reference and orientation, and where proximity influences action and reciprocity; • habitation where people can be aware of others across and within rooms, and where they can inhabit particular rooms;
