Mouse Accuracy Test

Click the center of each target as they shrink from 80px to 16px. Your average offset in pixels measures your fine motor precision.

How This Test Works

1

What It Measures

Measures fine motor precision by presenting targets that shrink from 80px to 16px. You must click the center of each target. Smaller targets require greater precision and steadier mouse control.

2

How Scoring Works

Score tracks click offset error (pixels from center). Smaller average offset indicates better fine motor control. Performance is governed by Fitts's Law — smaller targets naturally produce larger offset errors.

What Affects Your Results

Mouse DPI settings, hand steadiness, visual acuity, and mouse surface consistency all affect your accuracy score. A consistent low-friction mousepad improves control repeatability.

What Affects Your Accuracy Score

  • Mouse DPI settings — lower DPI (400-800) reduces hand tremor amplification for tighter clicks
  • Hand steadiness — caffeine, fatigue, and temperature affect fine motor tremor
  • Visual acuity — sharper displays make target centers easier to identify precisely
  • Mouse surface — a consistent, low-friction mousepad improves control repeatability

Frequently Asked Questions

What is the Mouse Accuracy test?

The Mouse Accuracy test measures your clicking precision by requiring you to hit targets that shrink over time.

What is the average accuracy score?

An accuracy score above 90% at moderate speeds is typical. Hitting smaller targets requires careful pointer control.

How can I train mouse precision?

Slow down your click rate, focus on clicking the exact center of targets, and ensure mouse acceleration is disabled in your OS.

Why do targets shrink in this test?

Target shrinking simulates time pressure, forcing you to balance speed with clicking accuracy before the target disappears.

Is mouse accuracy test diagnostic for tremors?

No. While motor tremors affect scores, this test is an educational gaming metric and not a clinical diagnosis tool.

What hardware setup is best for mouse precision?

Use a high-quality mousepad, a gaming mouse with zero sensor acceleration, and clean mouse feet.

Does mouse grip style affect accuracy?

Yes. Claw and fingertip grips offer precise micro-adjustments for small targets, while palm grip is better for large sweeps.

Can I play this test on a trackpad?

You can, but trackpads have high translation latency and lack microswitch buttons, which will significantly lower your accuracy scores.
