In this chapter, we showed that a close examination of the task geometry can explain how our digits move when we reach out to grasp an object. The laws that govern this behavior are similar to the ones that describe single-digit goal-directed movements. As with any movement, the selection of endpoint depends on why one is making the movement, and the trajectory is under continuous visual guidance, influenced by constraints imposed by obstacles and by the need to be precise.
