We humans can reach out and grasp objects with amazing accuracy. If you need something, like a cup of coffee, it is usually a simple matter to look where you remember leaving it, reach out and pick it up. But think about how complicated that process actually is and how remarkably well you do it. When you reach out to pick up the cup of coffee, not only do you direct your arm towards the cup, the posture of your hand and fingers anticipates the size, shape and orientation of the cup well before contact is made. One of the things that make this possible is your keen sense of vision.

我们人类能够以惊人的准确性伸手抓住物体。如果你需要什么东西，比如一杯咖啡，通常很简单，看看你记得把它放在哪里，伸手把它捡起来。但想想这个过程实际上有多复杂，而你做得又有多好。当你伸手去拿咖啡杯时，你不仅把手臂指向杯子，而且你的手和手指的姿势在接触之前就已经预测到了杯子的大小、形状和方向。使这成为可能的因素之一是你敏锐的视觉。
