Vision guides action by providing information about the target, the environment, and how the movement should unfold. Instead of relying on proprioception alone, the system actively searches the scene for task-relevant cues—like where a target is, how it’s moving, where obstacles lie, and timing signals—that help shape the upcoming movement. Anticipatory fixations, where the gaze briefly lands on a location ahead of the movement, let the brain pre-program the limb trajectory and align eye and hand so the action is timed and guided with less delay. This visual sampling is broader than just looking at the target; it’s about extracting informative cues from the surroundings to anticipate what will happen and adjust the plan as needed. In other words, vision acts as a guiding and predictive tool in motor control, integrated with other sensory and motor information to achieve precise, coordinated actions.
