A stylus is a small, pen-like tool used to interact with touchscreens and digital devices. It allows for more precise input than fingers, making it ideal for tasks like drawing, writing, or navigating apps. Styluses can be made from various materials, including plastic and rubber, and some are designed to mimic the feel of a traditional pen or pencil. Many modern devices, such as tablets and smartphones, support stylus use, enhancing the user experience. Popular styluses include the Apple Pencil for iPads and the Samsung S Pen for Galaxy Note devices. These tools often feature pressure sensitivity, enabling artists to create detailed digital artwork.
