A "swipe" gesture is a common touch input used on devices like smartphones and tablets. It involves sliding a finger across the screen in a specific direction, such as left, right, up, or down. This action can trigger various functions, such as scrolling through content, switching between apps, or navigating menus. Swipe gestures are often used in user interfaces to enhance navigation and improve user experience. For example, in social media apps like Instagram or Twitter, swiping left or right can help users browse through posts or stories quickly. This intuitive method allows for seamless interaction with digital content.
