This term refers to any mother-world space that has been 'shaped', (graphically drawn into the virtual world). It is a fast way of 'space-shaping' or attaining a virtual platform. This correspondence between the real and virtual can be used to ease orientation and enhance a known realspace. The space is effectively filmed, before a special application draws the given dimensions into the virtual. If the user was then to maneuver around the space, feeling the objects present, the system would require a direct link between real and virtual motion.
