Pointing devices are input tools that allow users to interact with a computer's graphical user interface. Common examples include the mouse, trackpad, and stylus. These devices enable users to move a cursor on the screen, select items, and execute commands by clicking or tapping. The primary function of pointing devices is to facilitate navigation and control within software applications. They translate physical movements into digital signals, making it easier to perform tasks such as drawing, gaming, or browsing the internet. Overall, pointing devices enhance user experience by providing intuitive ways to interact with technology.
