The micro-gravity environment causes some physiological changes on human body. Spatial disorientation (SD) is one of the most important aspects and it has strongly been desired to develop a monitoring method in current space medicine. Referring to the previous physiological and psychological studies, the pupil and eye movement have potential to be an objective indicator for the SD phenomenon.
In this paper, at first, a system for measuring pupil size and eye movement, by digital processing of eye images, was developed. Then, the system was applied to rotating-stripe and rotating-chair experiments, each of which causes SD of the subject, to evaluate the changes in pupil activity and eye movement during the SD phenomenon.
