Perception of static orientation in a constant gravitoinertial environment.
The illusions associated with the perception of static tilt in various specific force environments have been reviewed and then classified in such a way that a simple perceptual model could be developed to account for the experimental data. The fundamental conclusion to be drawn from this model is that these illusions can be accounted for by a simple non-linear transformation of the information primarily from the saccule.
