Abstract
Roll circularvection is an illusion of self-rotation about the fore-aft axis experienced when a stationary subject is exposed to a visual field rotating in the frontal plane. In these experiments, subjects have been asked to estimate the strength of this phenomenon while undergoing visual stimulation in the upright and supine positions, and during parabolic aircraft flight. The results indicate that the steady roll component of vection is not affected by the magnitude or direction of the gravity vector. The unpredictable and sudden loss of this compelling illusion could contribute to serious episodes of pilot disorientation.
