Abstract

In the researches of space flight,studies of the effects of microgravity on visual orientation were relatively few.This paper reviews recent progress on this topic.It surveys the spatial orientation problems encountered in spaceflight including 0-G inversion illusions,visual reorientation illusions,EVA height vertigo,and spatial memory problems described by astronauts.A vector model for sensory cue interaction was briefly described.
