Gesture recognizers are the simplest way to handle touch or press events in your views. You can attach one or more gesture recognizers to any view. Gesture recognizers encapsulate all of the logic needed to process and interpret incoming events for that view and match them to a known pattern.

What is gesture input?

In gesture recognition technology, a camera reads the movements of the human body and communicates the data to a computer that uses the gestures as input to control devices or applications. ... The gestures of the body are read by a camera instead of sensors attached to a device such as a data glove.

How do gesture sensors work?

Position-based gesture sensing involves finding gestures based on the calculated location of an object while phase-based gesture sensing is based on the timing of the changes in signal to determine the direction of an object's motion. This application note focuses on detecting gestures made by a user's hand.
