目的通过比较不同任务条件下的持续追踪时间,考察在多目标追踪范式下个体的手眼协调追踪绩效。方法采用多目标追踪的变式,志愿者用鼠标操控红色方块—飞机,躲避运动的若干蓝色方块—干扰物,飞机碰触到干扰物或灰色边界,任务结束,记录志愿者的持续追踪时间。结果志愿者的手眼协调追踪绩效受到干扰物速度和数量的影响。当运动速度加快或干扰物数量增加,持续追踪时间下降。结论手眼协调绩效受到干扰物速度和数量的影响,速度和干扰物数量的增加使追踪成绩直线下降。
Objective To compare the performance of hand-eye coordination tracking under multi-objective tracking paradigm by comparing the duration of follow-up under different tasks. Methods Using a multi-target tracking variant, volunteers manipulated the red square with the mouse-aircraft to avoid movement of several blue squares -interferents, the aircraft touched the interferent or the gray border, the task ended, and the volunteer’s continuous tracking time . Results Volunteers’ hand-eye coordination tracking performance is affected by the speed and number of obstructions. As the speed of movement increases or the number of interferers increases, the duration of continuous tracking decreases. Conclusions The performance of hand-eye coordination is affected by the speed and quantity of interfering objects. The increase of the speed and the number of interferents makes the performance of tracing decrease linearly.
