Mouse tracking test for sensor skips and accuracy
Trace a live mouse cursor path to test sensor tracking, movement skips and pointer stability in your browser.
Start the mouse testTrace a path to check mouse tracking accuracy
Move slowly in circles and diagonals. The browser records the visible cursor path so you can compare skips, direction changes and surface behaviour.

How to diagnose mouse sensor tracking skips
Draw slow circles, diagonals and straight lines inside the canvas. A sudden gap or sharp direction change can point to a dirty sensor, an unsuitable surface or a browser event scheduling limit. Repeat the same pattern on a mouse pad and a second computer before treating the result as a hardware fault. For FPS gaming, trace fast diagonals and flicks as well as slow circles because high-speed tracking can reveal skips that a slow path hides.
