A Mouse Accuracy Test measures how often you hit on-screen targets, how close those hits land to the centre, and how quickly you acquire each target. It is not a CPS (clicks-per-second) test and it does not read hardware DPI. The percentage on the result sheet uses one official hit-ratio formula, except in Tracking mode, which uses on-target time instead.
Accuracy (%) = Hits ÷ (Hits + Misses) × 100. Clicks outside the target count as misses, so extra clicking cannot inflate the score.
Tracking accuracy (%) = time on target ÷ session time × 100. Hits and misses are still counted for context, but the percentage is dwell time, not click ratio.
For each hit, offset is the Euclidean distance from target centre: √(Δx² + Δy²). Average click offset is the mean of those hit distances. Lower is tighter centering.
Milliseconds from the moment a target appears until a successful click. This is an extra metric on the result sheet, not a second accuracy percentage.
Small, Flick, and far-apart targets are simply more difficult to hit. The session percentage still uses Hits ÷ (Hits + Misses) × 100 (or on-target time in Tracking). Changing size or mode does not switch in a second scoring equation.
For repeatable gaming-style comparisons, keep your operating-system pointer acceleration and sensitivity settings consistent between sessions. Windows "Enhance pointer precision" introduces speed-dependent pointer displacement that changes cursor feel.
DPI (Dots Per Inch) determines cursor displacement per physical inch of travel. Higher DPI increases cursor speed, which can make micro-corrections more sensitive. Choose a comfortable sensitivity that balances reach with center precision.
This metric represents cumulative pixel displacement in browser coordinate space. It does not measure physical desk movement distance, as browser events do not capture surface travel without calibrated hardware counts.
This tool is designed to test your session-specific target acquisition, click precision, and cursor consistency within a standard web browser. To maintain absolute technical credibility, it is important to understand what a browser application can and cannot observe:
Official score: Accuracy (%) = Hits ÷ (Hits + Misses) × 100. Tracking mode instead uses time on target ÷ session time × 100.
Euclidean distance √(Δx² + Δy²) in CSS pixels measures deviation from target centers to evaluate precise hand placement.
Target reaction latency measures elapsed milliseconds between visual target spawn and successful click registration.
Visual spatial mapping highlights systematic click offsets, revealing whether user aiming tends to under-flick or over-flick.
Test input is processed in your browser. This tool does not upload your pointer coordinates or click positions.
