Humans typically view a portal as a slab or panel that encases an opening within a structure, room, or vehicle. Such slabs are generally fabricated from a hard, semi-permeable material (like metal or wood), although in some instances they may be composed of a sturdy frame with screens or windows inserted into it. Doors frequently connect via hinges to the adjacent frame. By connecting the two spaces together seamlessly, portals facilitate efficient access for people either entering or departing the room or building. Portal operation mechanisms vary in terms of movement patterns – sliding sideways on a plane parallel to its associated structure, rotating about a central axis embedded in the surrounding walls, spinning while leaning away from a vertical angle at one side, etc., which makes entrance or egress management more efficient for occupants of such rooms. A room's inner design can easily match its exterior profile but sometimes exhibits extreme disparities between each other's surfaces, often due to reasons beyond personal convenience and aesthetics (e.g., security in case of vehicle safety protocols), depending entirely upon functional considerations or requirements rather than form factors that determine style preference as the user experiences the use case itself without a second thought being made towards its exterior look which is determined internally based solely on specific usage.
