The saccades' path is influenced by visual distractors, making their trajectory curve away or toward them. Previous research suggested that the more salient distractor, pronounced curvature. We investigate saliency of spatial features, predicted a constrained maximum entropy model to be optimal non-optimal information carriers in fast vision, using them as distractors saccadic task. Their effect was compared luminance-based control distractors. Optimal features evoke larger curvature and magnitude direction deviation change function delay between distractor saccade onset. Effects were similar those found with high-luminance versus low-luminance Therefore, model-predicted interfere target-oriented saccades, following dynamic attraction-repulsion pattern. This suggests visuo-oculomotor system rapidly automatically processes optimally informative while programming visually guided eye movements.
