[sparse]
spaces are almost entirely devoid of sensory stimulation, to the point where one becomes hyper-aware of one's own presence.
e.g. desert, tundra, waiting room.

[saturated]
spaces are continual bombardments of visual and sonic input. environments like these range from beautiful to nausea-inducing.
e.g. glowstick rave, times square, coney island.

[personal]
spaces revolve around one individual's experience, tailored either by their physical construction, or by the individual's perception of the space.
e.g. bedroom, workspace, coffeeshop.

[anonymous]
spaces are generally public spaces that are stripped of any personal relevance. they are often sanitized and cold, and serve visitors rather than inhabitants.
e.g. airport, office building, the DMV.

[claustrophobic]
spatial boundaries are uncomfortably close to the inhabitant. these spaces induce oversensitivity, paranoia, and a need for escape .
e.g. elevator, airplane, rush-hour subway.

[vast]
spaces with boundaries so distant and amorphous that boundaries lose relevance. feelings of freedom and flight comingle with feelings of irrevocable insignificance.
e.g. mountains, oceans, deserts; bridges and cathedrals.
