Kinematics of eye movement control

In this paper a kinematic description of the restrictions imposed on the eye movements is presented. The restrictions arise from a pattern of nonlinear interactions between desired changes in viewing direction and current eye position. It is shown that various reported relations between eye torsion and viewing direction can be derived by changing only the relative weights of the interaction terms. This descriptive scheme may help to elucidate the control of eye torsion in the brainstem.
