    "abstract": "The personal spatial structure of an observer is introduced as a central\nelement in the positioning of objects in space. The link between a reference\nframe used by an observer and his personal spatial structure is discussed.\nResearch on inversion or reversal of incoming light in psychology indicates\nthat the personal spatial structure of an individual, as well as a reference\nframe that he uses, depends on the internal coordination of sensory stimuli and\nthat the position of objects in space depends in part on psychological factors\nthat affect one\u0027s personal spatial structure. Other research in psychology\ndemonstrating the flexibility for an observer in determining the direction of\nup-down relative to a particular figure, and indeed relative to the entire\nsurround, is also noted and supports the thesis that the observer plays a role\nin the positioning of objects in space.",
