| We have previously argued that two independent tasks, grasping static objects and intercepting moving targets, are each controlled on the basis of certain task-specific requirements. If this is correct, then we expect the same requirements to control the movement when the two tasks are combined. We propose to evaluate whether this is so. Considering the additional complexity of the combined task of grasping a moving object, we propose to shift from hitting moving objects to picking them up in a number of steps. Carefully studying each step, both empirically and in terms of modelling, will hopefully allow us to identify the critical requirements at each stage. |
