How to use this test

What to do

Place fingers on the field one at a time and check that the active count increases with each contact.

What to look for

Lift your fingers between attempts. The maximum is the largest number the browser reported together.

Contact positions, identifiers, and pressure come from Pointer Events where available. Pressure may be a default value on unsupported hardware. Browser gestures and palm rejection can interrupt contact tracking.
