What a page can read
9 gesturesA page cannot tell a touchpad from a mouse or see your fingers. It only gets the pointer, buttons, scrolling and zoom; the table shows what each gesture turns into.

Smooth and notched scrolling
With the same two-finger swipe, a precision touchpad sends many small scroll events that slow down after you lift. An old driver sends notches, like a mouse wheel.

NotchedWide gaps, equal bars, no inertia
1Precision touchpad
Built into Windows: scrolling comes in pixels and coasts after you lift, so it is smooth.
2Old driver
An old vendor driver sends wheel notches, so scrolling stutters and has no inertia.
3How this page decides
Small, steady steps that fade out are smooth; wide gaps and equal bars are notched.

Frequently asked questions
12 questionsWhat can this touchpad test check?
All common gesturesThis page tests a touchpad, also called a trackpad, for movement, tapping, double-click, right-click, drag, vertical and horizontal two-finger scroll, and pinch zoom. Safari also reads rotation, and Safari on a Mac reads press force.
How do I test if my touchpad is working?
Light up all 8 itemsMove a finger, tap, tap twice, right-click, drag, scroll and pinch in the test area. Each item lights up when the browser gets that action; one that stays dark points to that gesture.
Can it tell a tap from a press?
NoA tap and a physical press reach the page as the same left click. To check tapping alone, tap without pressing and see the Click item light up.
Can it test three- and four-finger gestures?
No, the system takes themThe system uses those swipes to switch windows and desktops, so they never reach the page. A three-finger tap set as the middle button does arrive.
Why does two-finger scroll move in notches?
Usually an old driverOn Windows, an old driver presents the touchpad as a mouse wheel, so scrolling stutters in the browser. Installing the vendor's precision touchpad driver makes it smooth.
Is mine a precision touchpad?
See system settingsOn Windows 11, open Settings → Bluetooth & devices → Touchpad; it says "Your PC has a precision touchpad" if it has one. The scroll signal on this page shows it too.
Will pinching zoom the page?
Not in the test areaIn the test area a pinch only changes the distance between the two fingers on the drawing. Outside it, the page zooms as usual.
Does it work as a MacBook trackpad test?
YesAs a Mac trackpad test, it works with MacBook trackpads and the Magic Trackpad. Safari adds rotation and press force, which Chrome and Edge lack.
Can it test haptic feedback?
Only press forceA page cannot measure the click you feel. Safari on a Mac reads press force, so the Force press item shows whether a hard press arrives.
How do I test a drifting cursor?
Use the still testIf the cursor moves by itself, run the still test on the sensor page with your hands off: it counts every report that arrives. Mouse sensor test →
Why does the scroll test not work with a touchpad?
It counts notchesThe scroll wheel test counts wheel notches, and a touchpad has none. Use the two-finger scroll items here instead. Scroll wheel test →
What if the touchpad does not respond at all?
Make sure it is onMany laptops switch the touchpad with Fn and an F key, and Windows settings have a touchpad switch too. Also check the option that turns it off when a mouse is connected.
