Pointer Event Inspector

View pointer type, ID, buttons, pressure, contact geometry, tilt, twist, timestamps, coalesced-event counts, and a copyable recent-event log locally in your browser.

Recent PointerEvents

No pointer events yet.

Pointer Events unify mouse, pen, and touch at the browser API level. Hardware-specific fields are only shown when the browser/device exposes them; zeros can mean “not applicable” or “not reported.”

Device diagnostic workflow

Start with a functional check, measure only what the browser can actually expose, then retest after one change.

ConnectChoose the actual browser-visible device or grant permission when required.

TestConfirm basic signal, input, output, preview or display behavior.

MeasureUse browser-exposed levels, timing, resolution, FPS, axes or event data.

DiagnoseCompare the symptom with the focused diagnostic rather than guessing from one number.

RetestRepeat after changing the device, cable, permission, browser or system setting.

Browser boundary
These tools observe browser APIs and local media/event streams. They cannot certify hardware condition, bypass denied permissions, or expose measurements the browser/OS does not provide.

Use the connected diagnostic workflow

Connect or select the device, confirm the basic function, inspect the browser-visible measurement, then open a focused diagnostic only when the symptom calls for it.

Browser-local does not mean laboratory measurement

These pages can report Web API data such as events, stream settings, frame timing and audio samples. They do not certify hardware condition or bypass browser and operating-system limits.
