Gesture-controlled systems are technologies that allow users to interact with devices through physical movements, rather than traditional input methods like keyboards or touchscreens. These systems use sensors, cameras, or other devices to detect and interpret gestures, enabling users to perform actions such as scrolling, selecting, or navigating by simply moving their hands or body. Common applications of gesture-controlled systems include smart TVs, gaming consoles, and virtual reality environments. They enhance user experience by providing a more intuitive and immersive way to control devices, making technology more accessible and engaging for a wide range of users.
