Orienting in real space (disposition of Moscow Metropolitan stations) and virtual space (the computer data base "Moscow") in blind and sighted persons is studied by comparison of semantic structures in everyday activity. It was shown by multidimensional scaling that though usual representation of disposition of Moscow Metropolitan stations is two dimensional, the dimensionality of mental representation of that space is equal three, i.e., real space is dramatically changed while mental model is formed. It was shown the principle similarity of mental structures provided subject's orienting in physical and informational spaces.
