Coordinates are CSS pixels after operating-system pointer settings. Speed is browser-visible cursor speed. They do not directly expose raw sensor counts, DPI, physical acceleration or lift-off distance.
Speed is cursor distance per elapsed time in CSS pixels. It reflects the transformed pointer path and does not directly measure sensor acceleration.
Avoid comparing across different zoom or monitor scaling. A browser may combine samples during fast movement.
For drift, leave the mouse still. For jitter, draw a slow straight line. For lift-off testing, add measured spacers yourself and observe when movement stops being reported.
No. Cursor movement has already passed through operating-system settings. A raw-input instrument and measured physical motion are needed to isolate acceleration.
Start the tracker and move the cursor inside the test surface. Use the trace and distance statistics to compare different movements.
No. Open the interactive tool above in a modern browser. The instructions and explanations are available even with JavaScript disabled; running a test needs JavaScript.
Power settings, background tasks, browser scheduling, operating-system input processing and device settings affect measurements. Compare repeated attempts with identical settings rather than the single highest score.
