Touch gestures are simple movements made on a touchscreen device, like a smartphone or tablet, to interact with apps and content. Common gestures include tapping, which selects an item, and swiping, which scrolls through pages or images. These actions make it easy for users to navigate their devices without needing a keyboard or mouse. Another popular gesture is pinching, which allows users to zoom in or out on images or maps. By placing two fingers on the screen and moving them closer together or farther apart, users can adjust the view. Overall, touch gestures enhance the user experience by making it more intuitive and engaging.
