Air Gesture is a technology that allows users to control devices through hand movements in the air, without needing to touch a screen or button. This interaction is made possible by sensors that detect and interpret the gestures, enabling a more intuitive way to navigate and operate devices. Commonly used in smartphones, tablets, and smart TVs, Air Gesture enhances user experience by providing a hands-free option for tasks like scrolling, zooming, or changing settings. This technology is particularly useful in situations where touching a device is impractical, such as when cooking or exercising.
