Cover legend: This motion capture image shows a human hand reaching toward and grasping an object. The spheres represent the reflective markers placed on the hand and arm to record movement kinematics. The colored lines leading the hand to the object represent the trajectories of the fingertips during reach. Humans are able to modulate fingertip contact points on an object when its properties can be anticipated. For more information, see the article by Lukos et al. in the April 4, 2007 issue (pages 3894–3903).
