Mouse Accuracy Test

About this test

Pointing accuracy rests on a well-documented trade-off: the faster you aim, the more you overshoot, and the more you have to correct. A pointing movement generally breaks into one fast impulse covering most of the distance, then one or more fine adjustments. Speed is what removes those adjustments, which is why accuracy drops the moment you push the pace. On a test of this kind, an ordinary user lands around 55 to 70 per cent once the targets get quick.

Mouse configuration weighs more than dexterity. Sensitivity set too high means systematic overshoot and double corrections; too low and you can't reach distant targets in the time available. Sensor and surface affect how repeatable the path is, and pointer acceleration enabled in the system makes the same gesture unpredictable depending on how fast you make it, which is accuracy's worst enemy. A wireless mouse adds a few milliseconds of latency, and a trackpad changes the exercise entirely since the finger has to reposition several times.

The measurement has limits. It mixes two things: hitting the target and getting there in time, since targets lost to expiry count as misses. It says nothing about your accuracy on moving targets, or your comfort over long sessions, where posture and shoulder fatigue matter far more.

How it works

Twenty targets appear one after another at random positions and sizes. Each stays visible for a window that shrinks as the run progresses. Every target you hit counts as a success; every target that vanishes before you click it, and every click that lands on empty space, counts as a miss. Your score is the share of successes across all clicks and targets presented.
