Complex and simple gestures
This term is defined by more than one standard, and the wording differs. Each definition below is the one that applies to that standard’s criteria.
Definition in RAWeb 1.1
A simple gesture involves touching a single point on the screen. It can be a single press or click, a double press or click, or a long press.
A complex gesture can be both a gesture involving several points of contact on the screen (e.g. a gesture with two fingers on the screen to zoom in or out on a map) and a gesture based on following a particular path on the screen (e.g. a JavaScript function that detects the movement of a finger to the left or right on a tactile surface to trigger switching to the previous/next item in a carousel).
