Gesture recognition is a technology that enables devices to interpret human movements as commands. It uses sensors, cameras, or touchscreens to detect gestures like waving, pointing, or swiping. This allows users to interact with devices without physical contact, making it useful in various applications, from gaming to smart home controls. The technology relies on algorithms that analyze the captured movements and translate them into actions. For example, a smartphone might recognize a swipe gesture to scroll through a photo gallery, while a gaming console could use hand movements to control characters in a video game.
