Tell a tap, a long press, a swipe and a drag apart on a touch screen

A finger is never perfectly still, so a tap turns into a tiny drag, a swipe fires a tap, or a held piece is picked up by accident. This entry shows how to make the AI sort one finger movement into exactly one kind, with rules that work on every screen density.

Why this works

A finger never stays perfectly still, so a gesture has to be judged by what the person meant, not by the exact touch points. Look at how far the finger ever went, then how fast, then how long. Judging only by where it ended misreads going out and coming back.

When not to use it

A fixed set of limits fits ordinary taps and swipes, but not games that need very fine control, such as drawing, or players who have trouble holding still. For them, make the limits adjustable and offer a plainer way to do the same thing.
