マウス精度

Mouse Accuracy measures your average distance from the center of each target you click, plus your hit rate. It's a direct benchmark of pointing precision — not a cognitive trait.

Twenty targets of varying size appear one at a time. Click as close to the center of each circle as you can. Clicking the background counts as a miss against your hit rate.

Your primary score is the average pixel distance from each target's center (lower is better), with your hit rate shown as a secondary metric. Results use estimated population norms.

Hardware, mouse sensitivity and display size all affect precision. This is a direct benchmark (Evidence C), not a clinical measure.
