How This Test Works
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.
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.
