Abstract Research on eye-hand coordination has focused action tasks performed in isolation. However, real world are often concurrently with perception that compete for gaze. Here we examine how participants adapt their eye and hand movements when performing an object manipulation task—in which they repeatedly grasped a ball inserted it into slot—while simultaneously monitoring text display to detect probabilistically occurring letter changes. We varied the visuomotor demands of task by having use either fingertips or tweezers. found fixations allocated were exclusively directed slot, more prevalent using The timing slot coupled time grasp entry. On average, gaze shifted away from landmarks ∼400 ms before contact fingertips—allowing peripheral vision direct hand—and around tweezers—further allowing central guide as approached slot. controlled movements, well patterns (sequence fixations) exploit temporal regularities task, thereby lowering probability change would occur during fixations. Our results illustrate can be flexibly intelligently adapted acting perceiving environment.
