Touch & input
10 to 20 seconds · Runs in this browser
Move your mouse through a large measurement surface to inspect delivered pointer-event frequency and timing stability. The test supports coalesced event samples when the browser exposes them and clearly explains browser limitations.
Move the mouse quickly and continuously inside the area. The graph uses pointer-event timestamps delivered by your browser.
Faster circles usually produce more event samples.
Input path: pointermove. Browsers and operating systems may coalesce or cap events, so this is not a USB analyzer reading.
Transparent method
This tool reports only interactions and browser APIs it can observe. It does not infer hidden hardware specifications or turn unsupported access into made-up results.
Useful context
The browser, operating system, movement speed, power mode, and event coalescing can reduce the frequency visible to a web page. Move quickly and compare repeated runs.
No. It measures pointer events delivered to the page, not packets on the USB cable. It is useful for browser-path comparisons but should not be presented as laboratory hardware measurement.
