Touch Screen Test Guide

How to use the touch screen test

Drag one or more fingers around the test surface. Each active contact gets its own marker, while the coverage grid records the parts of the surface that received input.

Understanding the results

Maximum touches reports the most simultaneous contacts delivered to the page. Coverage helps reveal areas that repeatedly fail to report a touch or drag.

What this browser tool can measure

Browser and operating-system gestures may reserve edge swipes or large multi-finger combinations. A web test cannot diagnose pressure sensitivity unless the hardware exposes it.
