Buttons held, movement, wheel, and clicks inside the pad. Not a DPI or polling-rate meter.

Coordinates are pixels inside the pad, not screen DPI. Pointer events per second are what this page received, not the sensor’s polling rate. movementX/Y is what the browser reports.
Worked example
Move inside the pad and the coordinates follow the pointer. Hold the right button and it stays listed as held until you release. The wheel total is the sum of deltaY the browser reports.
FAQ
- Are the coordinates screen pixels?
- They're CSS pixels inside the test pad, from its top-left. That is not DPI.
- Does this measure polling rate or DPI?
- No. The events-per-second figure is how many pointer events this page received. movementX/Y is what the browser reports. Neither is the sensor’s polling rate or DPI.
- Does a trackpad count?
- Yes, as a pointer. Touch on a phone is not a mouse, and the page says so.
