汽车需要从前方道路的变化模式中获得视觉信息。关于驾驶员可能使用的功能有很多理论（1-3），最近设计自转向车辆的尝试已经引起了对所涉及机制的兴趣（4，5）。然而，很少有直接的信息将转向性能与驾驶员的注视方向联系起来（3）。我们同时记录了方向盘角度和驾驶员在沿着曲折道路行驶时的视线方向。我们发现，司机特别依赖于“切点”和每个曲线的内部，寻找这个点1-2秒之前，每个弯曲，并返回到它在整个弯曲。该点相对于汽车行驶方向的方向预测了前方道路的曲率，我们研究了如何使用这些信息。
STEERING a car requires visual information from the changing pattern of the road ahead. There are many theories about what features a driver might use(1-3), and recent attempts to engineer self-steering vehicles have sharpened interest in the mechanisms involved(4,5). However, there is little direct information linking steering performance to the driver's direction of gaze(3). We have made simultaneous recordings of steering-wheel angle and drivers' gaze direction during a series of drives along a tortuous road. We found that drivers rely particularly on the 'tangent point' an the inside of each curve, seeking this point 1-2 s before each bend and returning to it throughout the bend. The direction of this point relative to the car's heading predicts the curvature of the road ahead, and we examine the way this information is used.
