Mice are compact input devices designed for precise cursor movement and navigation on electronic screens, particularly computers. They facilitate user interaction with digital interfaces by translating hand movements into electrical signals that control on-screen pointers or cursors. Mice typically feature a sleek, ergonomic design to ensure comfort during prolonged use and often incorporate optical or laser technology for smooth tracking across various surfaces. In addition to standard computer mice, there are specialized variants tailored for specific applications, such as gaming mice with adjustable DPI settings, wireless travel mice for portability, and trackball mice that offer alternative ergonomic solutions. Accessories like mouse pads, particularly hard ones, provide a stable, consistent surface to enhance tracking performance and prolong the lifespan of the device.
