Abstract :
Gaze control in three dimensions is achieved by the geometrical arrangement of the extra-ocular muscles. For head-fixed saccadic eye movements, the ocular rotation axis is constrained according to Listing´s law. In this paper, an ocular model is developed to control gaze. Quaternions associated with eye positions and rotations are used to precisely describe the axis of rotation.
