The VOR stabilizes images on the retina during rapid head motions: Rotations and translations of the head in three dimensions must be compensated by appropriate rotations of the eye. Because the head's rotation axis is not the same as the eye's rotation axis, the calculations for proper image stabilization of an object must take into account diverse variables such as object distance from each eye, gaze direction, and head translation ([Viire et al.1986]). The stabilization is achieved by integrating information from different sources: head rotations from the semicircular canals of the inner ear, head translations from the otolith organs, eye positions, viewing distance, as well as other context information, such as posture (head tilts) or activity (walking, running) ([Snyder and King1992]; Shelhamer et al.,Shelhamer92; [Grossman et al.1989]). In this paper we concentrate on the context modulation of the VOR which can be described by the kinematics of the reflex, i.e. eye position, eye vergence and head translation.
