前言 在复杂的操作员环境中,有时有必要改变一个正在进行的运动并继续朝向一个新的目标。我们探讨了为达此目的的极限因素。方法 8名被试者瞄准面前的目视目标。在一个百分比的试验中,目标位置改变,需要以±45°改变运动的方向而不改变射程。位移发生在目标出现之后25～100ms,即在可以开始运动之前。用Watsmarts系统将瞄准反应无接触地作 Preface In a complex operator environment, it is sometimes necessary to change an ongoing movement and continue toward a new goal. We explored the limits to this end. Methods Eight subjects were aiming at the visual target in front of them. In a one-percent test, the target position changes and the direction of the movement needs to be changed by ± 45 ° without changing the range. Displacement occurs 25 to 100 ms after the target appears, ie before it can begin to move. Aiming reaction with Watsmarts system will be made without contact
