Mouse and Touchpad Test
Use the test zone to validate movement, left click, right click, double click and scroll behaviour detectable by your browser. It works for laptop touchpads, USB mice, Bluetooth mice and similar pointing devices.

About the mouse and touchpad test
This tester gives you a live view of everything your pointing device sends to the browser: cursor coordinates, left, right and double clicks, scroll events and — where the browser can tell — whether the input came from a mouse, touchpad or pen. Move, click and scroll inside the test zone and every event is counted and displayed as it happens.
It is designed to answer practical questions quickly. Does the double-click register as two clicks or one? Does the cursor track smoothly, or jump when your palm brushes the pad? Does scrolling produce events in the direction you expect? Watching the raw event stream removes the guesswork that makes pointing-device faults so frustrating to describe.
The classic diagnosis it enables is separating a failing device from bad settings. A touchpad that jumps here as well as on the desktop has a hardware or driver problem — moisture, dirt or a swollen battery pressing from below are common culprits. One that behaves perfectly here but misbehaves in one application points straight back at that application.
What it looks like in use
Reading mouse and touchpad events
The test area logs pointer movement, click counts, double clicks and scroll direction. It helps identify whether the browser receives normal input from your pointing device.
What this test checks
- Pointer movement and coordinates inside the test zone.
- Left click, right click, double click and total event activity.
- Scroll direction and scroll count from a wheel, touchpad or Magic Mouse style device.
- Pointer type where the browser can distinguish mouse, pen or touch-like input.
How to understand your results
- A good result shows smooth coordinate changes, reliable clicks and scroll counts that match what you do.
- Jumping coordinates can point to dirt, moisture, palm rejection issues, Bluetooth interference or a failing touchpad.
- If right click is missing, check tap-to-click, two-finger click and secondary click settings.
- Some gestures never reach the browser because the operating system uses them for desktops, back/forward navigation or zoom.
Common problems and fixes
Cursor jumps around
Clean the touchpad, dry your hands, disconnect other pointing devices and check palm rejection settings.
Clicks do not register
Try both physical click and tap-to-click, then inspect accessibility and touchpad driver settings.
Scroll direction feels wrong
Natural scrolling settings differ between Windows and macOS. Change the OS setting rather than the browser.
External mouse behaves differently
Test the mouse on another USB port or surface, and replace low batteries in wireless devices.
FAQ
Can this test multi-touch gestures?
Only browser-exposed pointer and wheel events are shown. Many three- and four-finger gestures stay at OS level.
Does it work with a normal mouse?
Yes. The same page is useful for USB, Bluetooth and built-in pointing devices.
Why does the page need focus?
The browser only sends reliable input events to the active page or focused test area.
Why does my double click sometimes register as one click?
If the second press falls outside the OS double-click time window it counts as two singles. Test deliberately here: consistent misses at normal speed suggest a worn button; occasional ones suggest the click-speed setting.
Can this detect mouse drift or ghost clicks?
Yes. Rest the device and watch the counters: coordinates creeping or clicks appearing without your touching anything confirm the fault is in the device, not your imagination.
My touchpad jumps while I type — is it broken?
Probably not. That is palm rejection failing, not a dead pad. Raise the palm-rejection or sensitivity setting, and if it only happens while charging, try another power adapter — electrical noise from cheap chargers is a known cause.
