Testing a touch screen.
Test a touch screen in your browser: the touches it takes at once, and a grid to find places that do not answer. Nothing is sent.

A cracked or worn screen often stops answering in one strip.
Touches at once.
Put fingers down one by one: each is drawn where it is, and the most at once is counted beside the number the device says it takes.
Every part.
Draw slowly over every square with one finger. Squares light as a finger passes; a strip that never lights is where the screen does not answer.
What a page cannot see.
The system can keep touches for itself, such as three- and four-finger gestures and the screen's edges, and then a page never sees them.
