Abstract
The visual exploration of a scene in relative motion with respect to the observer requires the joint action of the two main oculomotor modes: the smooth pursuit mode to stabilize the scene with respect to the head, and the saccadic mode to capture the visual targets. The coordination of these two modes is studied in the case of reading eye movements. We provide a quantitative description of the changes that displacements of different amplitude, direction and velocity induce in the parameters of the saccadic sequences. The possible strategies for planning a saccade to a moving visual target are discussed and compared with the results. It appears that such planning has access to, and is contingent upon, information on the smooth pursuit components, and therefore that the coordination of pursuit and saccadic movements entails more than the simple vectorial summation of the two components.
