To fixate moving visual target, or stationary target when head is moving {fixation, vision}|, vertebrates combine vestibular system, vision system, neck somatosensory, and extraocular proprioceptor movement-sensor inputs. For vision, eyes jump from fixation to fixation, as body, head, and/or eyes move. At each eye fixation, body parts have distances and angles to objects (landmarks). (Fixations last long enough to gather new information with satisfactory marginal returns. Fixations eventually gather new information too slowly, so eyes jump again.)
