Observe pointer movement, clicks and wheel events inside a test area. This gives a quick view of what the browser receives from a mouse or trackpad.
How to use this tool
- Move the pointer into the test area.
- Try clicks and wheel or trackpad scrolling.
- Compare the displayed event information and coordinates.
How to interpret the result
The page reports browser events rather than raw hardware signals. Pointer acceleration, operating-system settings and touchpad gestures can affect results. It does not measure sensor DPI, polling rate or input latency.
Frequently asked questions
Why does scrolling outside the area do nothing?
The test listens within its designated area. Move back into that area to observe the relevant events.
