Mental representation of spatial structure in a virtual room-sized space

To keep spatial awareness in virtual multilevel building, navigator should understand the spatial structure of space. Mental representation of spatial structure in a virtual cylindrical room was investigated in present experiments. Participants first observed two static views of space in which the two viewpoints were on the same vertical plane but with different heights, and then either judged the relative direction of object in the first experiment or egocentrically pointed out the direction of object in the second experiment. The results suggested that the orientation-dependent representation of spatial structure was created even though participants could learn the space from two different viewpoints lying on the vertical dimension of space.
