Eyes and hand movements are known to be coordinated during a variety of tasks. While steering a vehicle, gaze was observed to be tightly linked with steering wheel angle changes over time, with the eyes leading the hands. In this experiment, participants were asked to drive a winding road composed of bends with systematically manipulated radii of curvature, under regular and automatic steering conditions. With automatic steering, the vehicle followed the road, but the steering wheel and participants hands did not move. Despite the absence of physical eye-hand coordination in that condition, the eye and [what the hands should have done] to produce the action on the steering wheel were found to be coordinated, as under regular steering. This result brings a convincing piece of evidence that eye movements do more than just guiding the hands. In addition, eye-hand coordination was also found to be intermittent, context and person-dependant.
眼睛和手部运动在各种任务中是已知协调的。在驾驶车辆时，随着时间的推移，观察到注视与转向盘角度的变化紧密相关，眼睛领先于手。在这个实验中，参与者被要求在有系统地操纵曲率半径的弯道组成的蜿蜒道路上行驶，在常规和自动转向条件下。在自动转向的情况下，车辆沿着道路行驶，但转向盘和参与者的手并没有移动。尽管在这种情况下没有实际的眼手协调，但发现眼睛和[手应该做的动作]与常规转向时一样协调，以产生对转向盘的作用。这一结果提供了一个令人信服的证据，即眼睛运动不仅仅是引导手。此外，眼手协调还发现是间歇性的，依赖于上下文和人。
