Mouse Tester: how to use the result
The mouse tester provides a small controlled area for observing button presses and wheel activity. It is useful when you want to check that left, middle and right presses are distinguishable or describe a scrolling problem. The counters summarize events delivered to this page; they do not inspect the physical switches inside the mouse.
How to use this workspace
- Move a mouse pointer inside the test area and press each button separately. Keep the pointer within the area while checking the counters.
- Scroll in both directions and observe whether wheel events are registered. Compare a short deliberate action with repeated actions.
- Reset before testing another mouse or connection so the two sessions do not share old counts.
A practical example
A left press followed by a right press should increase those counters independently when both events reach the page. The test area suppresses its context menu to make a right press observable. A middle click may behave differently outside the test area because the browser assigns it another action.
How to interpret your result
Counted events establish that the browser received input during this session. They do not translate directly into physical travel, precise scrolling distance or a measured double-click interval. One wheel movement may produce several events depending on the device and system settings.
Common mistakes and limits
Touch and pen input are excluded from this mouse-specific check. System gestures, remapping software and browser focus can change what arrives. An unexpected count deserves a repeat under the same conditions before you conclude that a button is defective.
Make the comparison repeatable
Test one condition at a time and note which device, browser and connection you used. If an unexpected result appears, repeat the same action before changing settings. A second browser or another known-working peripheral can help separate an application or permission problem from a device problem. Keep those comparisons descriptive: this page observes what reaches the browser and does not have access to a laboratory measurement of the hardware.
Frequently asked questions
Does this measure mouse polling rate?
No. The implemented counters observe button and wheel events. They do not provide a calibrated polling-frequency or latency measurement.
Why do I see different wheel counts on two mice?
Wheel hardware, smooth-scrolling behavior and operating-system settings affect event delivery. Compare whether input is received, rather than assuming equal counts mean equal physical movement.
