Touch gestures are actions performed on a touchscreen device, such as a smartphone or tablet, to interact with the interface. Common gestures include tapping, swiping, pinching, and long-pressing. Each gesture serves a specific function, like opening apps, scrolling through content, or zooming in on images. These gestures enhance user experience by providing intuitive ways to navigate and control devices. For example, a tap can select an item, while a swipe can move between screens. Understanding these gestures allows users to utilize their devices more efficiently and effectively.
