🎯 瞄准训练Aim Trainer
在线鼠标瞄准训练：屏幕上随机出现靶子，尽快点中它们。经典模式依次击中 30 个靶子，统计平均用时和命中率；限时模式 30 秒内靶子会逐渐缩小，看你能命中多少个。三种靶子大小，自动记录最好成绩，鼠标和触屏都能练。Online mouse aim trainer: targets pop up at random spots and you click them as fast as you can. Classic mode times 30 targets and reports your average time and accuracy; 30-second mode shrinks every target until it disappears, so see how many you can hit. Three target sizes, personal bests saved, works with mouse or touch.
点击（或用手指点）红白相间的靶子。点空会降低命中率；经典模式的最好成绩看平均用时（越低越好），限时模式看命中个数（越多越好）。Click or tap the red-and-white target. Missing lowers your accuracy; the best score in Classic mode is the lowest average time, in 30-second mode the most hits.
玩法说明与常见问题How to play & FAQ
「瞄准训练」怎么玩？How do I play Aim Trainer?
点击「开始」后靶子会出现在画面的随机位置，击中后马上出现下一个。经典模式记录从上一个靶子出现到你击中它的时间，30 个后给出平均用时和命中率；限时模式中每个靶子会在一两秒内缩小消失，消失前没点到就算一次失误。可以先用大靶子找手感，再换小靶子练精度。After you press Start a target appears at a random spot, and the next one appears as soon as you hit it. Classic mode measures the time from each target appearing to your hit and reports the average and accuracy after 30; in 30-second mode each target shrinks away in a second or two and counts as a miss if you don't get it in time. Warm up with large targets, then switch to small ones to train precision.
平均多少毫秒算快？What average time is fast?
大靶子经典模式下，多数人在 500～700 毫秒之间，熟练的鼠标用户可以达到 400 毫秒左右。触屏、鼠标灵敏度和屏幕大小都会影响成绩。With large targets in Classic mode most people average 500–700 ms, and practised mouse users get around 400 ms. Touch screens, mouse sensitivity and screen size all affect the result.
和反应时间测试有什么区别？How is this different from a reaction time test?
反应测试只测看到信号后按下的速度；瞄准训练还要求你移动指针并准确点中目标，更能反映手眼协调能力。A reaction test only measures how fast you respond to a signal; aim training also requires moving the pointer and hitting the target accurately, so it reflects hand–eye coordination.
